If you're heading to Koh Chang and want a sea trip that packs "several islands into one day," the island-hopping snorkeling tour is probably the first name that comes to mind. The islands around Koh Chang sit inside Mu Ko Chang National Park in Trat province, and include several small islands with clear water and shallow reefs where you can float above schools of fish — Koh Wai, Koh Rang, and the Koh Yak group. They're not far from Koh Chang itself, so the whole thing works comfortably as a day trip.
The speedboat version leaves from a pier on Koh Chang's west coast in the morning, loops through roughly 3-5 snorkeling spots, then heads back to shore in the afternoon. On this page we'll give you an in-depth review of the tour itself — both the parts people fall in love with and the parts you should brace for — based on real reviews from people who've actually gone.
Koh Chang Island-Hopping Snorkeling Tour (Speedboat — Koh Wai, Koh Rang, Koh Yak, Mu Ko Chang National Park)
The day typically starts with the tour team picking you up from your resort on Koh Chang's west coast in the morning, or meeting you at the pier. After a safety briefing and handing out snorkel masks and life jackets, the speedboat leaves the pier and heads into Mu Ko Chang National Park. The first stop of the day is often the reef around Koh Yak Yai-Yak Lek, where the water is shallow and clear enough to float and watch schools of fish without needing to be a strong swimmer. From there it's on to Koh Rang, one of the Trat coast's best-known snorkeling spots, with a wide reef and plenty of fish, before wrapping up at Koh Wai, a small island with clear water and a beach where you can rest and swim along the shore.
Around midday, most tours stop for lunch — some serve it on Koh Wai itself, others on the boat — then give you extra time to swim and snorkel before heading back to Koh Chang in the afternoon. The per-person price for a join-group speedboat usually includes lunch, fruit, drinking water, and snorkeling gear, and many operators also include a transfer from west-coast resorts. If you want more privacy and the freedom to choose your own stops, private charters are available too, though at a noticeably higher price.
Based on real reviews across several platforms, the things people consistently praise are the clear water, the shallow reefs that are easy to view, and the attentive crew, who do a good job helping weaker swimmers during snorkeling. On the downside, the boat ride to the snorkeling spots takes a while and the waves can get fairly rough at times — on rough days, seasickness is common and uncomfortable. Another issue is that around midday, many tour boats converge on the same spots at once, so some areas get crowded and the water turns murky from all the snorkelers stirring it up, and some coral shows signs of bleaching and degradation from weather and heavy use, so you shouldn't step on or touch the coral. Finally, during the monsoon season (May-October) the waves are rougher and underwater visibility drops, and some operators suspend service.

💡 Know before you go on a Koh Chang snorkeling tour
The morning departure reaches the first spot before other boats — the sea tends to be calmer than later in the day, the water is clearer, and there are noticeably fewer people. Better conditions for photos and for snorkeling comfortably.
Speedboats slam into waves hard. If you get seasick easily, take motion-sickness medication about half an hour before boarding, sit toward the middle of the boat where it rocks the least, and look at the horizon if you start feeling dizzy.
The snorkeling spots are inside Mu Ko Chang National Park, so there's an additional entrance fee — around 40 baht for Thai adults and around 200 baht for foreigners. It's usually charged separately from the tour price, so bring cash to pay at the pier.
Choose a reef-safe sunscreen (free of oxybenzone/octinoxate) so you don't harm the coral, some of which is already showing signs of bleaching. Don't step on or touch the coral, and bring a long-sleeve shirt and a sun hat since you'll be out in the sun for most of the day.
