Planning your dive trip to Koh Tao or just looking forward to some relaxed beach days? In this honest Koh Tao packing list, I’ll show you what really belongs in your backpack and what you can safely leave at home.
Koh Tao is hot, tropical, and extremely laid-back. Between dives, scooter rides, and lazy afternoons on the beach, you don’t actually need much. But there are a few things that make life on the island a lot easier (and others that just take up unnecessary space).
During my time as a dive instructor on the island, I made just about every packing mistake possible, from overpacking my suitcase to bringing things that didn’t survive the humid island climate for long.
Whether you’re coming for diving, snorkeling, or just to unwind, this Koh Tao packing list will help you pack only the essentials, so you can spend more time enjoying the island and less time lugging around heavy bags.

Koh Tao Essentials
Before you fully switch into island mode, there are a few Koh Tao essentials you definitely shouldn’t forget, especially if you’re here for diving, snorkeling, or exploring the island by scooter.
- Passport & Dive Certs: Take a photo of both and save them offline on your phone.
- Travel & Dive Insurance: Make sure it covers both outpatient and inpatient treatments in Thailand. For diving a specialized insurance (e.g., DAN) is the gold standard.
- Dry Bag or Waterproof Backpack: Essential for boat trips, sudden tropical rain showers, and beach days.
- Reusable Water Bottle: Most shops offer free refills. Better for your wallet and the ocean.
- Quality Flip-Flops: You will basically live in them. Get a comfortable, sturdy pair that won’t slip on wet boat decks.
- Charging Hub or Multi-Plug: Many accommodations on Koh Tao seem to have only one single, well-hidden power outlet. If you want to charge everything at once, a charging hub is your best friend.
- Quick-Dry Towel: High humidity means towels take forever to dry. Microfiber is your friend.
- Laundry Bag: A lightweight cloth bag keeps the chaos in your backpack under control until you it off at a local laundry.
- Polarized Sunglasses: A must-have! The glare on the water is intense.
- Sarong: The ultimate island all-rounder. Use it as a beach towel, a skirt, or even as sun protection on the boat.
What to Wear on Koh Tao
Island life is hot, humid, and laid-back. “Dressing up” usually just means throwing a clean t-shirt over your swimwear. If you pack smart, everything should fit into a daypack.
My “Island Uniform”:
- 5–6 Tops/Tees: Lightweight and breathable fabrics only.
- 2–3 Shorts: Quick-dry is best.
- 2 Simple Dresses: For evenings or an easy outfit change.
- 1 Light Hoodie: Essential for freezing ferries or windy boat rides.
- 1 Rain Shell: Tropical downpours come out of nowhere.
- 2 Pairs of Socks: Only if you plan on wearing sneakers.
- 7x Underwear: Enough for a week before laundry day.
- 2–3 Bikinis/Boardshorts: You’ll be in the water constantly.
- 1 Buff/Neck Gaiter: Great for sun protection or dust during scooter rides.
- 1 Pair of Sneakers: Only for hiking (like John-Suwan) or scootering.
- 1 Good Pair of Flip-Flops: You will wear these 95% of the time.
Laundry Tip: Pack for one week max. Local laundries charge ~40–50 Baht per kilo and return your clothes clean and folded within 24 hours. Don’t overpack!

Dive Gear: What to Bring vs. What to Rent
You don’t need to bring your entire kit to Koh Tao unless you’re obsessed with your setup (like I am). Rental gear on the island is generally solid, but a few personal items make a massive difference in comfort.
The “Must-Brings”
- Mask: A leaking rental mask ruins a dive. Your own mask is small, light, and the ultimate comfort upgrade.
- Dive Computer: Most shops charge extra for rentals. Plus, you’ll know your own menus by heart and keep your logs accurate.
- SMB & Spool: Boat traffic is heavy on Koh Tao. As an instructor, I never dive without one. Safety first.
Optional (If you have space)
- Regulators: Peace of mind comes with knowing your regs are freshly serviced. Koh Tao uses Yoke (INT) valves. If you have a DIN reg, bring an adapter or check with the shop first.
- Dive Torch: Essential for night dives or spotting macro life in crevices. These aren’t always available for rent.
- 3mm Full Wetsuit: Most shops provide shorties. If you’re a “freeze baby” like me and get cold after 40 minutes, bring your own long suit.
Leave at Home (Rent locally)
- BCD: Bulky and heavy. Most island rental BCDs are in good condition.
- Fins & Weights: Weights are always included. Rental fins are standard everywhere unless you specifically need boots and open-heels.
Always inspect the rental gear on day one. If you need Nitrox or Sidemount tanks, email the shop in advance to confirm availability.

My Personal Dive Setup for Koh Tao
Since I’m often in the water for two or three dives a day, I’ve refined my gear over the years for maximum comfort and utility:
- 3mm Full Wetsuit: Even in 29°C water, repetitive diving leads to heat loss. A long suit also protects against jellies and minor scratches.
- My Own Mask: Nothing beats a low-profile mask that fits so perfectly you forget you’re wearing it.
- Backplate & Wing: My favorite setup. It offers much better stability and trim than a standard jacket-style BCD.
- DIN Regulators with Yoke Adapter: This keeps me flexible so I can use my own regs on any tank on the island.
- Tec Fins: While Koh Tao doesn’t have many strong currents, I prefer the direct power and feel of stiffer fins.
- SMB & Line Cutter: Safety first. Due to the heavy boat traffic, I never surface without deploying my buoy.
- Small Torch: Perfect for spotting macro life in crevices or for a spontaneous night dive at White Rock.

Toiletries & Hygiene
Keep it simple and travel-friendly. Focus on products that help you recover from salt, sun, and humid scooter rides.
Pack these in your bag
- Reef-Safe Sunscreen: Thailand has strict bans on chemicals like Oxybenzone or Octinoxat. True reef-safe cream is expensive and hard to find on the island. Buy it before you arrive, I personally use Stream2Sea.
- Hair Conditioner: Saltwater and sun are the “final boss” for your hair. A good conditioner is a lifesaver after a long day at sea.
- Basic Kit: Toothbrush, toothpaste, deodorant, and razor (travel sizes are enough).
Buy these locally (at 7-Eleven)
- After-Sun Lotion: Local Aloe Vera gel is the best remedy for a “Thai pink” sunburn.
- Mosquito Repellent: Local brands work much better against Thai mosquitoes. My favorite is the pink Soffell spray.
- Refills: You can find shampoo and shower gel in every shop on the island.
Warning: Many Thai products (lotions, deodorants, even sunscreens) contain skin-bleaching agents. Look out for “whitening” on the label if you want to keep your natural tan!
Electronics for the Island
When it comes to tech on Koh Tao, think: small, light, and salt-resistant. The tropical humidity and salty air are tough on electronics, so protection is key.
What’s in my tech bag:
- Smartphone: Essential. Don’t forget your charger.
- Power Bank: A lifesaver for long travel days or full days out on the dive boat.
- GoPro / Underwater Camera: Bring spare batteries! Nothing is more frustrating than a Whale Shark showing up while your screen stays black.
- Spare Cables: Salty air kills cables faster than you’d think. Bring a backup for your most important devices.
- Laptop or Tablet: Only if you need it for work, backing up photos, or serious trip planning.
Compact Travel Pharmacy Kit
You don’t need a mobile hospital, but a few targeted basics will save you a lot of stress on the island.
- Antiseptic & Bandages: Minor cuts can become infected incredibly fast in tropical heat and saltwater. Clean every scratch immediately with iodine (e.g., Betadine) or antiseptic spray.
- Ear Drops: Essential for divers. Note that the classic vinegar/alcohol mix used to prevent swimmer’s ear is often hard to find in local pharmacies.
- Electrolytes: The combo of heat, sun, and diving dehydrates you faster than you realize. A few sachets of rehydration salts (like Elotrans) work wonders for exhaustion or the occasional “Thai belly.”
- Painkillers: Ibuprofen or Paracetamol are fine. Crucial: Avoid Aspirin if there’s any chance of Dengue Fever, as it thins the blood.
- Motion Sickness Meds: If you’re sensitive to waves, bring tablets with Dimenhydrinate. The ferry crossing to Koh Tao can get quite “sporty.”
- Fenistil or Tiger Balm: For itchy mosquito bites or if you accidentally brush against a stinging jelly.
What you do NOT need to bring to Koh Tao
Save your back (and the hassle of moving bags across beaches and ferries). Leave these behind:
- Too many shoes: You’ll live in flip-flops. One pair of sneakers for the flight or a hike is plenty.
- Bulky towels: They never dry. Bring one small quick-dry towel instead.
- Full-size toiletries: Heavy and annoying to pack. Travel sizes are enough, you can buy refills everywhere.
- Vapes: Illegal in Thailand. The fines are massive. Seriously, don’t risk it.
- Fancy outfits or heavy makeup: Nobody really “dresses up” here. Bikini, boardshorts, and a clean tee is the vibe.
- Too many clothes: Laundry costs ~40-50 Baht per kilo. Pack less, wash often.
Packing Rule: If you’re standing over your bag wondering “Do I really need this?” – the answer is no.
