Scuba Diving at Koh Chang: HTMS Chang Wreck & Coral Reefs

Two dives, two worlds: a sunken warship and living coral gardens

Scuba diving at Koh Chang for certified divers includes two dives daily around either the HTMS Chang shipwreck or Koh Rang National Park's shallow reefs, with a professional guide, hotel pickup, lunch, all equipment and drinks. A third dive can be added for an extra fee. The operator chooses the best sites based on weather and currents, and speaks English, French, German and Thai.

The experience

The day starts with hotel pickup and ends eight hours later back at your accommodation. You're diving two sites chosen for conditions on the day you go: either the HTMS Chang, Thailand's largest shipwreck, paired with two coral reef dives, or two vibrant coral sites inside Koh Rang National Park where the water stays shallow and calm. The guide is certified and speaks your language. All equipment is provided, so you bring only your certification card and a willingness to be in the water twice.

The HTMS Chang route suits divers who want depth and structure: the wreck itself rises through the water column, so you see it from different angles across the dive, and the reef stops afterward balance the intensity with easier coral gardens. Koh Rang National Park goes the opposite direction: the reefs sit in shallow water among tropical fish and soft corals, the pace is relaxed, and the marine park setting means fewer boats and less current. Either way, the guide navigates the site and stays with the group. You handle your own buoyancy and air consumption.

Lunch and drinks are included, served between dives. If you want a third dive, the operator adds it for 1,000 baht. You arrange this at checkout or ask on the day. The boat leaves early enough that you're back with time to rest before evening, and the whole operation runs around the weather and sea state, so the sites you actually visit depend on what's safest and clearest when you arrive.

Is this one for you?You're a certified diver ready to navigate the sites yourself with a guide present, not a classroom setting, and not a spectator experience. The operator picks the best dive based on conditions that morning, so you're not locked into a single plan. The wreck route suits divers who want depth and structure, while Koh Rang works better if you prefer calm, shallow reefs and a slower pace.

Top questions

What languages is the guide in?

Live guide in English, French, German, Thai, Chinese and Dutch.

What's the difference between the HTMS Chang dive and Koh Rang National Park?

The HTMS Chang route takes you to Thailand's largest shipwreck plus two coral reef dives, suited for divers comfortable with depth and wreck structure. Koh Rang National Park offers two shallow coral sites in a protected marine park with calm waters and abundant fish. The pace is easier and the setting is more secluded.

Do I need to bring my own diving equipment?

No. All scuba gear is included: wetsuit, tank, regulator, BCD and weights. Bring your certification card and a mask if you prefer your own fit, but everything else is provided.

What time does the day start and end?

Hotel pickup happens in the morning, and the full day runs eight hours before you're dropped back at your accommodation. The exact pickup time depends on your hotel location and the day's dive plan.

Can I add a third dive?

Yes. A third dive costs 1,000 baht and can be arranged at checkout or requested on the day, depending on time and conditions.

Is this trip suitable for divers with limited experience?

You must hold a valid scuba certification to participate. The operator chooses sites based on weather and guest preferences, so both wreck and reef options can accommodate divers of different levels, but certification is required for all divers.
