The main choices

One island, several very different dive days.

There is no single “best” trip. The right choice depends on depth, certification, when you last dived, what you want to see and which boats are running.

Wreck and reef

HTMS Chang plus a coral site

A combination day built around Thailand’s largest shipwreck and a contrasting reef dive.

  • Normally two dives
  • Good for suitably experienced certified divers
  • Wreck plan depends on certification and conditions
Choose this for the wreck.
Coral and marine life

Koh Rang National Park

A reef-focused day with coral formations and varied marine life in the national park area.

  • Usually two or three coral dives
  • Suitable for many experience levels
  • National park fee is additional
Choose this for reef variety.
Flexible local diving

Koh Chang local reefs

Local sites can be a sensible choice for newer divers, mixed groups or a relaxed return to the water.

  • Sites selected for the day’s conditions
  • Refresher or tune-up can be discussed
  • Some boats also welcome snorkelers
Choose this for flexibility.
Which trip fits?

Start with your experience, not the sales brochure.

Returning diverDiscuss how long it has been and whether a tune-up is sensible.
Wreck-focusedShare your certification, logged dives and depth experience for an HTMS Chang recommendation.
Mixed groupTell me who dives and who snorkels so a suitable scheduled boat can be checked.

Common questions

Useful answers before you choose.

Do I need a scuba certification?

Yes, the dive trips on this page are for certified divers. If you have never dived before, look at the Discover Scuba Diving option instead.

Can I dive the HTMS Chang?

Possibly. The appropriate dive plan depends on your certification, recent experience, comfort at depth and the conditions on the day.

Can a snorkeler join the same boat?

Often, but not on every trip or schedule. Send the makeup of your group so a suitable option can be checked.

Is equipment included?

Standard rental equipment is normally included in the trip price. Mention any personal equipment, unusual sizing or special requirements in advance.

Which sites will we visit?

The operator confirms the route according to the schedule, diver suitability, weather and safety. A requested site cannot always be guaranteed.
