Is Koh Kood diving worth it, and who is it for?

Koh Kood is a diving add-on more than a dive hub. Operators here run small boat trips to local reefs and a full-day run to Koh Rang. Groups are small, with one Koh Kood operator listing a maximum of 4 divers per instructor or guide.

Beginners get the clearest benefit. Shallow sites such as Soneva Reef (12 m) keep first dives relaxed. Certified divers get a wreck and a marine park, but not a long menu of sites. If you want a dozen different dives in a week, look at diving from Koh Chang instead. Our Koh Chang diving guide covers that side.

Non-divers in your group are not left out. Snorkel trips run on the same boats. More on that further down.

Koh Kood dive sites and the depth you need

Operators list five regularly serviced sites. Match the depth to your certification before you book.

HTMS Chang is the headline. The wreck is about 100 m long and sits around 30 m deep, and it was sunk for recreational diving. That depth is beyond the 18 m Open Water limit, so plan on Advanced or Deep training. Our HTMS Chang wreck guide covers the dive in more detail.

Blueberry Hill is a coral-covered pinnacle. Its top is about 3 m and it slopes to a 15 m sandy bottom, north of Hin Rap Tai. Soneva Reef holds hard coral and often turtles, stingrays and scorpionfish. Banana Bay and Hin Ao Yai are listed as suiting beginners and advanced divers, with some parts for training and some for drift dives.

• HTMS Chang wreck: about 30 m, needs Deep or Advanced training
• Blueberry Hill: 3 m to 15 m, suits Open Water divers
• Soneva Reef: 12 m, suits beginners
• Banana Bay and Hin Ao Yai: mixed training and drift sections

Best season for Koh Kood diving

One Koh Kood operator runs its diving season from mid-October to May. Marine park trips run on set days and only when weather allows. Outside those months, expect fewer departures and rougher seas.

Check sea conditions with your operator a day or two ahead. For wider context on monsoon timing, see our Koh Chang diving season guide. Both islands sit in the same part of the Gulf of Thailand, so the broad pattern is similar.

Courses, fun dives or a Koh Rang day trip?

Pick by experience, not by price. One Koh Kood operator lists these formats. Its figures are single-operator listings, not market rates. The PADI course overview shows how agency course levels are structured.

Koh Kood diving costs and booking

One Koh Kood operator lists Basic Diver at ฿3,500 for 1 dive or ฿5,000 for 2 dives. Marine park diving adds a ฿400 entrance fee per diver. A Koh Rang snorkel trip is listed at ฿1,400, and a snorkel trip around Koh Kood at ฿1,000. Prices and hours checked November 2026; confirm current rates with your operator.

Those figures include lunch, snacks and hotel pickup on Koh Kood. Open Water and Advanced course prices were not listed, so ask for a written quote. Book Koh Rang days early because they run on only three days a week.

Getting to the boat: Koh Kood versus Koh Chang

Check your departure island before paying. One operator lists a boat leaving Bang Bao bay at 9am. Its Koh Kood trip returns around 3pm and its Koh Rang trip around 5pm. Bang Bao is on the Koh Chang side. Staying on Koh Kood, the same operator lists hotel pickup, with Marine Park trips collecting around 8:00 to 8:45 AM.

Crossing times and ferry timetables change by season, so use the pier operator's current schedule. Koh Chang divers who want a different mix can compare local sites in our Koh Chang dive sites guide.

Koh Rang is the shared option. Day trips there run on Tuesday, Thursday and Saturday, weather permitting. Our Koh Rang Marine Park day trips page covers that island.

Snorkeling alternative for non-divers

Mixed groups can split by activity. Snorkelers join trips with about 1 hour in the water at each of 3 stops at Koh Rang. Details are in our guide to snorkeling around Koh Kood. Another nearby option is snorkeling off Koh Mak.

Mistakes to avoid when booking Koh Kood diving

Three errors cause most problems.

• Booking without checking the departure island: Bang Bao and Koh Kood pickups are different trips.
• Assuming the wreck suits Open Water: HTMS Chang sits near 30 m and the Open Water limit is 18 m.
• Flying too soon after diving: follow Divers Alert Network or your agency's no-fly guidance, and leave a safe gap before your flight.
