Use this travel brief to set arrival flow, local transit, and gear movement before you lock your itinerary.

Quick Facts

Primary airport: Trat Airport (TDX)
Typical transfer: 20 km drive to the Laem Ngop pier area (approx)
Entry requirement: Thailand entry rules depend on nationality and can change.
Getting around: Getting around is straightforward but varies by island.

Getting There

Most trips start in Bangkok, then connect east to Trat Province.

Fastest route: Fly Bangkok (BKK) to Trat (TDX) on Bangkok Airways, then transfer by road to the ferry piers for Koh Chang or to Laem Sok Pier for Koh Mak and Koh Kood boats.
Overland route: Buses and private transfers run from Bangkok to Trat and the Laem Ngop pier area (roughly 315 km by road). This can be a good option if you are traveling with bulky dive gear.
Ferries and speedboats: Koh Chang is reached by frequent ferries from the Laem Ngop area. Koh Mak and Koh Kood are typically reached by speedboat or catamaran from Laem Sok Pier, with some routes stopping on Koh Mak en route to Koh Kood.

If you are island hopping, avoid tight same-day connections in the May to October monsoon window because crossings can be delayed or cancelled.

Getting Around

Getting around is straightforward but varies by island.

Koh Chang: Songthaews (shared pickup taxis) run along the west coast, plus private taxis and scooters. Roads can be steep and slick after rain.
Koh Mak: Quiet roads make cycling popular. Scooters and golf-cart style rentals exist depending on accommodation.
Koh Kood: Fewer roads and more distance between beaches, so most visitors use scooter rentals or resort taxis.
Mainland Trat: Shared vans connect the airport, town, and piers.

For dive days, most operators include pier pickup in the main beach zones, but confirm the meeting point the night before.

Entry Requirements

Thailand entry rules depend on nationality and can change.

Check the official Thailand e-Visa portal if you need a visa in advance, or if you want to apply online.
Many travelers enter under visa-exemption rules for tourism, often with stays measured in weeks rather than days. Confirm the current allowance and extension options with an official Thai embassy or consulate before you fly.
For island hopping near the Cambodia border, carry your passport (or a secure copy) for transport checks and hotel registrations.

Also check for any current digital arrival or immigration form requirements before departure.

Gear Logistics Checklist

Dive gear is easy to manage here, but plan around small-island realities.

Flights: If you fly to Trat, confirm baggage allowances for your ticket type and pack regulators and cameras in carry-on when possible.
Rentals: Major operators on Koh Chang, Koh Mak, and Koh Kood rent full kits and provide tanks and weights on the boat.
Rinse and dry: Bring a small dry bag for boat days and a lightweight clothesline for humid evenings.
Spare parts: Small islands have limited inventory. Pack spares like mask strap, fin strap, mouthpiece, and basic O-rings.

Practicalities

Currency

Thai Baht (THB)

Cash is useful for songthaews, small restaurants, and pier payments. Cards are common at resorts and larger restaurants, but do not assume every beach bar or minimart accepts them.

ATMs are common in the busier parts of Koh Chang and in Trat town, but can be limited on smaller islands. Carry a backup card and do not wait until your last day to withdraw cash.

Electricity

220V • 50Hz • A, B, C, O

Thailand commonly uses a mix of plug types. A universal adapter helps, and most modern chargers are dual-voltage.

Communications

Mobile coverage is generally good on Koh Chang in main beach areas, with AIS, True, and DTAC widely used. On smaller islands and remote bays, expect occasional dropouts. Buying a local SIM or eSIM is usually the easiest option for short trips.

Language

Thai is the main language. English is widely spoken in dive shops, resorts, and tour desks, while more remote areas may rely on simple phrases and gestures. Keep accommodation details written down for taxi rides.

Insurance

Carry travel insurance that covers scooter use (if you plan to ride) and marine activities. Divers and freedivers should add dedicated dive accident coverage (for example DAN) for evacuation and recompression treatment.

Packing list

In-water: Rashguard, reef-safe sunscreen, and a 3mm wetsuit if you get cold on repeated dives.
Boat days: Dry bag, reusable water bottle, seasickness medication if you are prone, and a spare set of O-rings.
Topside: Light rain jacket (especially May to October), mosquito repellent for evening meals, and grippy sandals for waterfall rocks.
Tech: Power bank and a universal adapter; humidity can slow drying for camera housings and wetsuits.
