Koh Chang Islands: Which to Visit & How to Hop (2026)
Koh Chang and nearby islands explained: Ko Rang snorkelling, Koh Mak, Koh Kood, how to hop between them, and how many days to plan.
On this page
Last updated November 2026: the Koh Chang islands are one large island, Koh Chang itself, plus the smaller islands of the Mu Ko Chang archipelago and its marine national park. Many searchers really want Ko Rang for snorkelling, or the neighbouring Trat islands of Koh Mak and Koh Kood. For a short stay, base yourself on Koh Chang and add one marine park day trip, then use our Koh Chang things to do guide to fill the remaining days.

What Are the Koh Chang Islands?
Koh Chang is both the main island and the name of the marine national park around it. Mu Ko Chang National Park falls under Thailand's national parks department. Smaller islands in the group include Koh Wai, Koh Rang, Koh Ngam and Koh Kham. Koh Mak and Koh Kood are the other big Trat islands. Treat them as separate trips rather than quick stops. Sources quote different island counts and size rankings, so this guide gives neither. Check the park authority for the current figures.
Which Island Is Right for You?
Pick by the kind of trip you want, not by the map. Koh Chang has the most beaches, restaurants and places to stay. Ko Rang is a snorkelling stop, not a base. Koh Mak and Koh Kood suit travellers who want quieter, smaller islands. Details below are limited to what is established; confirm boat times with an operator.
Add 1–2 nights for Koh Mak or Koh Kood because each extra island leg eats into a short stay.
| Island | Character | Access | Ideal length | Best for | Trade-off |
|---|---|---|---|---|---|
| Koh Chang | Largest island, jungle hills, many beaches | Ferry from Ao Thammachat on the mainland | 3–4 nights | Beach choice, dining, base for day trips | Hilly, winding west-coast road |
| Ko Rang | Small marine park islet | Boat tour from Koh Chang | Half day to full day | Snorkelling, clear water, coral | Depends on season and sea conditions |
| Koh Mak | Smaller and calmer than Koh Chang | Separate boat leg; confirm operator | Add 1–2 nights | Quiet stays | Extra ferry time |
| Koh Kood | Smaller, greener, low-key | Separate boat leg; confirm operator | Add 1–2 nights | Slow-paced stays | Furthest hop in the group |
Island Hopping from Koh Chang: Routes, Time and Cost Trade-Offs
Do not assume one ferry links every island. Koh Chang is reached from the mainland pier at Ao Thammachat, and our Koh Chang Ferry: Piers, Times, Fares and Booking page covers that crossing. Onward hops to Koh Mak and Koh Kood use separate boats. Operators and seasonal gaps change, so confirm schedules before you book a bed on the next island. Every extra island adds ferry legs, and a two-night trip can lose a large share of its time to them. Fares are not sourced here, so compare current operator quotes. Group tours usually cost less per person than a private boat. A private boat gives you control over timing and weather.
- Default for short stays: stay on Koh Chang and book one Ko Rang tour.
- Longer stays: split the nights between Koh Chang and one neighbour.
- Avoid hopping through three islands in under five nights.
Snorkelling the Marine Park Islands: What to Know Before Booking
Ko Rang is the usual snorkelling target in the park. Tours leave from Koh Chang, so compare group boats with a private charter. Group tours cost less, but you share time at each stop. Visibility is reported to peak in the middle of the dry season. Rough seas can cancel or spoil a trip. Ask the operator what happens to your booking if the weather turns. Pick the pier and boat type based on your base. If you stay near the southern piers, you shorten the transfer, but check current departure points. Read the park authority's notices for closures or fees.
How Many Days Do You Need?
Two nights is enough for one beach day and one snorkelling trip, but ferries will take a large share of your time. Three to four nights suits most visitors, with time for the marine park, a couple of beaches and a slow dinner. With five nights or more, add Koh Mak or Koh Kood rather than spending everything on one island. Our where to stay guide helps you choose a base. Read Koh Chang Beaches: Which One to Pick (Compared) notes before choosing between the busy and quiet stretches.
| Nights | Realistic plan | Skip |
|---|---|---|
| 2 | Koh Chang beach plus one Ko Rang tour | Koh Mak and Koh Kood |
| 3–4 | Koh Chang, two or three beaches, Ko Rang | A second island unless the weather is settled |
| 5+ | Koh Chang plus one neighbour island | Hopping three islands |
Best Season for Island Hopping
November to April is the dry season, which brings calmer seas and more reliable crossings. May to October is the wet season, when some resorts and tour operators reduce service. Even in the dry season, showers and rough water can still happen. Check forecasts with the Thai Meteorological Department before fixing a snorkelling day. Our Best Time to Visit Koh Chang: Season-by-Season Guide guide breaks the months down. Book early for the busiest dry-season weeks.
Getting There and Around
From Bangkok, plan roughly 5–6 hours including the ferry, as commonly quoted. Confirm current times before you go. Our How to Get to Koh Chang: Routes, Ferry & Transfers page compares the options. Details for the capital route are in Bangkok to Koh Chang: Bus, Van, Car & Ferry Compared. Flying lands you at Trat, covered in Koh Chang Airport: Does It Exist? Nearest Airport and How to Get There. Roads on the island are steep and winding. Read Getting Around Koh Chang: Songthaew, Scooter & More before choosing a scooter.
Budget roughly 5–6 hours from Bangkok, which matters most for a two-night plan with one beach day and one snorkelling trip.
Common Mistakes to Avoid
A few planning errors cost the most time on this trip.
- Assuming all islands connect by one ferry.
- Underestimating the hilly road time between beaches.
- Booking the snorkelling day in a poor-weather window.
- Treating the dry season as guaranteed sunshine.
- Cramming three islands into a two-night stay.
