Derawan Packing List: What to Bring

How to read this: Maratua Resort is an independent concierge guide — we curate and compare dive resorts and island stays in the Derawan archipelago, then arrange your booking through a vetted operating partner. We do not own or operate the resorts, and resort or brand names are used only as neutral examples, not claims of affiliation. Prices are by quote and vary by resort, season and party; figures here are indicative. Flights, transfers and dive seasons change — confirm before you travel. This is general information, not a binding offer.

Derawan packing list means planning for a remote island chain with limited shops, salt-spray boat rides and strong equatorial sun. This guide walks through what to pack for Derawan so you’re covered for diving, snorkeling and simple island life without overloading your bag.

The non‑negotiables for the Derawan Islands

Derawan, Maratua, Kakaban and Sangalaki are remote, low‑infrastructure islands off East Kalimantan. Once you leave Berau or Tarakan, you cannot assume you’ll find specific brands, sizes or even basics in stock.

These are the derawan islands essentials I treat as non‑negotiable.

1. Passport, IDs and travel documents

Passport with at least 6 months’ validity (for international guests).
Printed and digital copies of flight e‑tickets (into/out of Berau/Tarakan).
Resort / homestay confirmations and airport–jetty transfer details.
Travel insurance documents, including emergency medical and dive cover if you plan to dive.
Driving licence (if you may rent a scooter on Derawan; availability is patchy).

Derawan transfers are often stitched across cars, small boats and local jetties. Phone signal can be weak, so don’t rely on finding emails in your inbox at the last minute—keep screenshots or printed copies.

2. Essential clothing for equatorial islands

Think light, quick‑dry, and sun‑smart more than fashion.

2–3 quick‑dry T‑shirts or loose long‑sleeve tops.
1–2 pairs of lightweight shorts.
1–2 pairs of breathable long trousers or leggings (for sun and mosquitos).
1 long‑sleeve sun shirt or rashguard for boat days.
1 thin hoodie or light sweater (early‑morning boat rides can feel cool in the wind).
Underwear and sleepwear that dry fast in humid air.
1–2 casual outfits if you’ll spend time in Balikpapan/Samarinda or Jakarta en route.

Laundry is often by hand and line‑dry. In the wetter months, things can take longer to dry, so synthetics outperform cotton.

3. Footwear that actually makes sense on Derawan

Most days you’ll walk between jetty, sand and boat decks.

Open‑toe sandals or flip‑flops: easy for boats and wet jetties.
Reef‑safe water shoes (or dive booties) for rocky entries and hot boards.
Light sneakers if you plan any city time or basic rainforest walks on Maratua.

High heels and heavy hiking boots are dead weight here.

4. Swimwear and cover‑ups

You will live in swimwear.

2–3 swimsuits or bikinis / boardshorts.
Rashguard or UV swim shirt (long‑sleeve is ideal).
Light sarong or beach cover‑up (works as towel, scarf, curtain, blanket).

Pack at least two sets so one can dry while the other is in use.

Reef‑safe and conservation‑minded packing for Derawan

Coral reefs around Maratua and the jellyfish lake on Kakaban are sensitive. One of the most high‑impact answers to “reef safe packing Derawan?” is simple: change what you put on your skin, not just what you bring in your camera housing.

5. Reef‑safe sunscreen (especially for Kakaban)

Many jellyfish lake operators now ask visitors to avoid standard sunscreens entirely. In practice, this means:

Mineral sunscreen with zinc oxide or titanium dioxide as the active ingredient.
SPF 30–50, water‑resistant, non‑aerosol.
Enough for your whole trip (you may not find reef‑safe brands locally).

Wear sun‑protective clothing so you use less sunscreen overall—better for your skin and the water.

6. Sun and bug protection beyond sunscreen

Equatorial sun and occasional mosquitos are part of life in the islands.

Wide‑brimmed hat or cap that won’t blow off easily in the wind.
Polarized sunglasses (preferably with a retainer strap).
Lightweight buff or neck gaiter (sun, dust and wind protection on boats).
Insect repellent (DEET or picaridin; consider applying only on land, away from the sea).
After‑sun lotion or aloe gel for mild burns.

Mosquitos tend to be more of an issue around dusk, especially in mangrove or lagoon‑fringed areas, so loose long sleeves and trousers help as much as repellent.

7. Low‑impact daily items

A few simple swaps reduce single‑use plastic on remote islands that have limited waste management.

Reusable water bottle (ideally insulated; many properties offer refill stations).
Compact reusable shopping bag for snacks or small purchases.
Travel cutlery set if you’re particular about avoiding disposable plastic.
Refillable toiletries in small bottles instead of hotel minis.

Trash gets off these islands slowly. Minimising what you bring in is its own small form of reef care.

Diving and snorkeling: what to bring vs what to rent

Not everyone needs a full derawan diving gear checklist; it depends on how frequently and how seriously you dive. The constant: gear choice is much narrower on the islands than in major dive hubs.

8. Core dive documents and certifications

Certification card(s) or digital proof (Open Water, Advanced, Nitrox, etc.).
Logbook (physical or app) to prove recent experience for advanced sites.
Medical statement if required by your operator (especially if you have pre‑existing conditions).
Dive insurance details and emergency contacts.

Some operators will refuse advanced drift walls or deep dives if you cannot demonstrate sufficient recent experience.

9. Personal dive gear: what I recommend bringing

Mask fit and comfort matter more than any other item.

Mask you trust, with strap protectors if you use them.
Snorkel if you plan unguided house‑reef swims or are fussy about style.
Fins that you’re used to; check with your operator if boat space allows long freediving blades.
Booties if using open‑heel fins and for rocky entries.
Computer (and spare battery / charging cable).
Reef‑safe defog if you can’t stand the smell of alternatives; baby shampoo also works.

You can generally rent full sets of gear through local operators, but sizing is limited, and the newest or smallest sizes go first in peak periods. Rental arrangements on Derawan and Maratua are usually quoted per‑trip via local dive operators rather than fixed posted rates.

10. Exposure protection: suit and accessories

Water temperatures in the Derawan area tend to sit in the high 20s °C much of the year, but divers who chill easily may still want more coverage, especially on repetitive dives.

3 mm full wetsuit is a good baseline for most divers.
5 mm suit or hooded vest if you get cold quickly or plan many days of 3–4 dives.
Rashguard and leggings for snorkeling only trips.
Thin hood or beanie for longer liveaboard‑style itineraries in the region.

Check our Best Time to Visit Derawan guide for seasonal water temperature patterns before deciding.

11. Safety and comfort add‑ons

Most Derawan operators carry basic safety kit, but for remote drifts around Maratua Channel and similar sites, I strongly prefer having my own.

Surface marker buoy (SMB) and spool/reel.
Audible signalling device (whistle) and optional small mirror.
Small cutting device (line cutter or blunt‑tip knife) used responsibly.
Reef hook only if your operator trains you and the site/policy allows it; never hook live coral.
Comfort mouthpiece if you’re sensitive to standard regs.

If you plan to freedive, consider your own low‑volume mask, snorkel, fins and weightbelt; specialist freedive gear is rarely available for rent on these islands.

12. Snorkeling‑only guests: keep it light but specific

For a snorkel‑focused holiday around Derawan, Kakaban and Sangalaki, I would still pack:

Mask and snorkel that fit you well.
Fins (full‑foot are fine for boat‑based snorkeling).
Long‑sleeve rashguard and leggings for sun protection instead of more sunscreen.
Reef‑safe sunscreen, hat, sunglasses and water shoes.

Some accommodations or local guides may have basic snorkel sets, but variability in fit, hygiene and quality is high. If you care about comfort, bring your own.

Money, power and connectivity: the realities

Derawan is not a “tap‑your‑card everywhere” destination. Cash, charging and patchy signal are part of the experience.

13. How much cash to bring

There are ATMs in Berau and in larger towns on the mainland. Once you’re on Derawan or Maratua, ATMs may be non‑existent or unreliable. Plan to bring enough Indonesian Rupiah for:

Any remaining transport not prepaid (cars, local boats, porters).
Park or conservation fees, if applicable in cash at jetties.
Snacks, small restaurants, local whale shark/ snorkel add‑ons where cards aren’t accepted.
Tips for guides, boat crew and homestay staff.

Many mid‑range and upmarket properties can accept card payments for accommodation packages, but card terminals may go offline with network outages. Having a cash buffer smooths things out significantly.

14. Cards, currency and small bills

Visa and Mastercard are the most widely usable cards in Indonesia.
Carry at least two different cards in separate locations (wallet and daypack).
Withdraw cash in Berau before heading to the jetty.
Ask for some smaller denominations (Rp10,000–Rp50,000) for snacks, drinks and simple meals.

Change can be a challenge in small warungs; having smaller bills makes life easier for everyone.

15. Power: voltage, adapters and load shedding

Most of the Derawan archipelago uses Indonesia’s standard:

220V, 50Hz electricity.
Type C and Type F plugs (two round pins; European‑style).

In practice:

Pack a universal adapter if your plugs differ.
Bring a small power strip if you have multiple devices; some rooms have limited outlets.
Consider a power bank; local grids can be fragile, and some smaller properties may run gensets on schedules.

Avoid high‑draw appliances like hair dryers unless your property explicitly supports them; many islands are on limited power.

16. Connectivity: mobile signal and Wi‑Fi expectations

Signal in the Derawan Islands is variable:

Derawan Island itself generally has better coverage than more remote atolls.
Maratua, Kakaban and Sangalaki can range from workable 4G to limited or no signal depending on exact location and prevailing network conditions.
Wi‑Fi, where provided, often relies on the same fragile backhaul and is not suitable for heavy work or streaming.

For a smoother experience:

Buy an Indonesian SIM (e.g. Telkomsel is often strongest in remote areas) in a city before flying to Berau.
Download offline maps of Berau, jetties and islands in advance.
Pre‑download entertainment and reading for quiet offline evenings.

If you need to work remotely, build in contingencies: offline‑capable tools, slack expectations from colleagues, and understanding that some days the connection simply may not cooperate.

Packing for Derawan boat transfers

Your journey will almost certainly include at least one small‑boat leg. That should shape how you pack.

17. Bags: hard suitcase vs soft duffel

Both can work, but soft is usually simpler on small boats.

Bag type	Pros for Derawan	Cons for Derawan
Soft duffel (with straps)	Easy to lift and stack on boats; compresses under bunks or in small rooms.	Less protection against hard knocks; needs packing cells for structure.
Hard suitcase	Protects fragile camera housings and electronics.	Awkward on narrow jetties, can be heavy and bulky to move into small boats.
Carry‑on backpack	Hands‑free boarding, keeps essentials with you.	Limited capacity; may be more exposed to spray.

If you travel with serious camera gear, many photographers use a hard cabin case plus a soft main duffel that can handle getting wet.

18. Dry bags and protecting electronics

Salt spray and sudden showers are routine on the crossing to Derawan and Maratua.

At least one 20–30L roll‑top dry bag for day trips (camera, phone, documents, light jacket).
Smaller dry pouches for passport, phone and cash.
Ziploc bags for quick extra protection and basic organisation.
Waterproof or at least water‑resistant case for your main camera or drone.

Keep passports and tickets in a small dry pouch that stays on your body during transfers, not buried in main luggage.

19. Sea‑sickness and comfort on boats

Not every crossing is rough, but conditions can change quickly.

Sea‑sickness tablets or alternative remedies if you’re prone to motion sickness.
Light scarf or buff to cut wind chill.
Small quick‑dry towel to sit on or wrap around shoulders.
Snacks and a water bottle for longer transfer days.

Eat light and avoid heavy, greasy meals before boat rides if you’re sensitive.

20. Camera and underwater photography gear

For many guests, Derawan’s manta, turtle and reef life are the star subjects.

Camera bodies and lenses or a capable compact / action cam.
Underwater housing with checked O‑rings and spare grease.
Strobes or video lights if you shoot underwater seriously.
Plenty of memory cards and at least one backup drive.
Laptop or tablet for daily backups, plus power bank.

Humidity is high. Use silica gel packs in your camera case and let cold camera gear warm up before opening housings to reduce fogging.

Toiletries, meds and “just in case” items

Island kiosks might sell basics like soap, toothpaste and simple snacks. Anything more specialised you should bring.

21. Toiletries you should not rely on finding locally

Your preferred shampoo/conditioner and body wash (in small, leak‑proof bottles).
Toothbrush, toothpaste, floss.
Deodorant.
Contact lenses and solution if you use them.
Period products (selection on the islands is very limited).
Razor and minimal grooming kit.

Pack liquids in double‑bagged pouches; many transfers involve baggage being handled quickly on wet jetties.

22. Personal medications and basic first aid

Access to pharmacies on the islands is extremely limited.

Any prescription medications, in sufficient quantity plus a small buffer.
Copies of prescriptions in case of emergencies.
Basic painkillers and anti‑inflammatories (ibuprofen/paracetamol).
Antihistamines (for allergies or mild reactions).
Anti‑diarrheal and oral rehydration salts.
Small first‑aid kit: plasters, sterile wipes, bandages, antiseptic cream.
Motion sickness tablets if needed.
Ear drops suitable for divers to help prevent infections (discuss with your doctor).

Serious medical issues are treated on the mainland; evacuation takes time. Good preparation plus insurance matters more here than in many city destinations.

What not to pack (or to question hard)

23. Heavy “just in case” items

Think twice about:

Bulky fashion outfits and multiple pairs of shoes.
Formal wear; dress codes are extremely relaxed.
Hair straighteners, large hair dryers and similar high‑draw appliances.
Large hard‑shell coolers or non‑essential camping gear.

Every extra bag is another piece to lift over a jetty edge and into a small boat.

24. Single‑use plastics and throw‑away gear

Try to avoid:

Cases of single‑use plastic water bottles—refill a durable bottle instead.
Cheap snorkel sets that will break and be left behind.
Disposable rain ponchos; a compact reusable jacket is better.

Remote islands feel the pressure of marine debris more than anywhere. Packing a little lighter and more thoughtfully genuinely helps.

How we can help refine your list

Maratua Resort is an editorial and concierge guide, not a dive centre or homestay. Our role is to help you compare islands and stays honestly, then connect you to a single trusted operating partner once you’re ready to book.

That also means we can sanity‑check your Derawan packing list:

Adjusting exposure protection based on your cold tolerance and likely water temperatures.
Advising on how many cash‑only costs to expect in your specific itinerary.
Clarifying what gear our partner can usually rent comfortably in your size and what is best brought from home.
Flagging any seasonal wrinkles (for example, more rain, more chop on certain routes) that might change how you pack.

If you’d like that level of detail, plan your trip with us or reach out on WhatsApp at +62 811 3823 875. No one can pay to change what we publish; if you proceed with our partner they may pay us a referral fee at no extra cost to you.

Do I need my own dive gear for Derawan?

No, you don’t strictly need your own full set; most diving is arranged via local operators who can provide rental gear by quote. That said, I strongly recommend bringing at least your own mask, snorkel, fins and computer for comfort and consistency, and your own wetsuit if you are difficult to fit or prone to getting cold.

Is reef‑safe sunscreen really necessary on Kakaban and Sangalaki?

“Necessary” depends on the specific operator and current local rules, but from a conservation perspective it is strongly advised. Jellyfish lakes and shallow reef tops are sensitive environments; mineral, reef‑safe sunscreen and UV clothing are the most responsible options and may be required by some guides before entering certain sites.

Can I buy snorkeling gear on Derawan Island?

You might find simple snorkel sets for sale or rent on Derawan Island, but quality, sizing and availability are inconsistent. If comfort and fit matter to you, especially for children or if you snorkel daily, it’s wiser to bring your own gear from home.

Are there reliable ATMs on Maratua, Kakaban or Sangalaki?

Assume that ATMs will be limited or unavailable once you leave the mainland. Plan to withdraw enough Indonesian Rupiah in Berau or another mainland town to cover incidentals, small cash‑only expenses and tips throughout your island stay.

How strict is the dress code on the Derawan Islands?

On the islands themselves, dress is very casual: shorts, T‑shirts and beachwear with simple cover‑ups are normal in resort and homestay settings. Respect local norms by covering up a little more in village areas—wearing a T‑shirt and shorts or a simple dress rather than just swimwear is usually sufficient.
