Dive Sites of Koh Chang

Wrecks, coral reefs and two different diving areas

Choose the dive area before chasing one famous site.

Koh Chang diving broadly divides into local sites—including the HTMS Chang—and the reefs around Koh Rang. Certification, recent experience, weather and the boat schedule all shape the best choice.

Start with the area

Two broad routes create very different dive days.

Local sites

HTMS Chang and nearby reefs

A local day may combine the landmark wreck with a coral site, or focus on reef dives that fit the group and conditions.

Marine park

Koh Rang reef area

A longer boat-day rhythm with a range of shallow reefs, rocky sites and deeper options chosen around the day’s conditions.

Individual site guides

Know the character—keep the final plan flexible.

These guides help you understand the differences. Actual site selection remains a safety and logistics decision on the day.

A deep, substantial wreck with changing visibility and different routes for suitably certified divers.

How site choice works

Conditions and experience outrank wish lists.

Visibility, current, waves, group composition, certification limits and park access can change the sensible route. Good planning keeps alternatives open.

Certification sets limitsDepth and overhead-environment training matter, especially around wrecks.
Recent experience mattersA certification card does not replace comfort, buoyancy control and familiarity with the equipment.
Weather changes the planA protected site may be a better dive than an exposed first choice when conditions shift.
The group mattersThe final route has to work safely for the divers and the boat operation, not just one person’s wish list.
Planning questions

Before requesting a particular site.

Can I book HTMS Chang specifically?

You can request it, but certification, recent experience, conditions and the operator schedule determine whether the wreck is realistic for your date.

Which area is best for beginners?

There is no single permanent answer. Suitable shallow reef sites exist in more than one area; the best choice depends on conditions and how the day is organised.

Can snorkelers join a dive-site trip?

Sometimes, but not every dive route provides good or safe snorkeling. Send the full group details so a shared option can be checked.

How do I choose between two and three dives?

Consider the route, travel time, recent experience and how comfortable you are with a longer day. The pricing page shows the current options.

Plan around the diver

Send your level, last dive and preferred date.
