How can I dive from Koh Samui with The Divers Boat?

From Koh Samui, take the Lomprayah ferry to Koh Phangan at 8am (arriving 8:30am). After a 30-minute transfer to Chaloklum, our boat departs at 10am for Sail Rock (1h15 crossing). Two dives, hot lunch on board, return to Chaloklum at 4pm, transfer to Thong Sala and the 5pm ferry back to Koh Samui (arriving 5:30pm). The return ferry, full equipment and lunch are all included in the price.

Is the Lomprayah ferry included in the diving Koh Samui price?

Yes. The Divers Boat's diving prices from Koh Samui include the Lomprayah return ferry between Koh Samui and Koh Phangan (8am-8:30am outbound, 5pm-5:30pm return). Full equipment and a hot meal are also included. No extras to book separately.

What level do I need to dive at Sail Rock from Koh Samui?

An Open Water certification (SSI, PADI or equivalent) is required for fun dives at Sail Rock. A try scuba is also possible as a day trip from Koh Samui via Koh Phangan — contact us to organise your diving day.

Q: Why dive from Koh Phangan and not directly from Koh Tao when staying in Koh Samui?

Koh Phangan is much closer to Sail Rock than Koh Tao (1h15 vs 2h by boat). Furthermore, our 10am departure from Koh Phangan is the only one compatible with the Lomprayah ferry from Koh Samui. Koh Tao centres depart at 6:30am — too early to catch this ferry.

Q: How much does diving from Koh Samui cost?

Count on 4,800 THB for 2 fun dives at Sail Rock (ferry and transfer included), or 5,800 THB for a try scuba with 2 dives at Sail Rock. These prices include the Lomprayah return ferry, full equipment and a hot meal on board.

Diving Koh Samui — Sail Rock Day Trip via Koh Phangan

Diving Koh Samui is easier than you think. Sail Rock — the best dive site in the Gulf of Thailand — is reachable as a full day trip, without leaving Koh Samui the night before. The idea is simple: take the 8am Lomprayah ferry in the morning, join the Red Boat in Koh Phangan — our dedicated vessel for Sail Rock departures — dive twice at Sail Rock and return to Koh Samui the same evening on the 5pm ferry. Indeed, our 10am departure is the only schedule in the Gulf compatible with this ferry.

How Diving Koh Samui Works — Your Day Step by Step

Our departure from Koh Phangan is at 10am — the only schedule in the Gulf compatible with the Lomprayah ferry from Koh Samui. Moreover, every trip includes full equipment, a hot lunch, and a dedicated guide with a maximum of 4 divers. Here is how your day unfolds:

8:00am — Lomprayah ferry departs Koh Samui
8:30am — Arrive in Koh Phangan (Thong Sala pier)
~9:00am — Transfer to Chaloklum (~30 minutes)
10:00am — The Red Boat departs for Sail Rock
11:15am — First dive at Sail Rock
12:30pm — Hot lunch on board (surface interval)
1:30pm — Second dive at Sail Rock
4:00pm — Return to Chaloklum pier, transfer to Thong Sala (~30 minutes)
5:00pm — Lomprayah ferry departs Koh Phangan, arriving Koh Samui ~5:30pm

Furthermore, every diving Koh Samui trip includes the Lomprayah return ferry between Koh Samui and Koh Phangan, full equipment and lunch. You therefore have nothing extra to arrange.
