5 Things to Know Before Planning a Dive at Sail Rock

Although Sail Rock is one of the most famous and exciting dive sites near Koh Tao, it’s not ideal for every diver. Located in an open sea, Sail Rock Thailand requires more time, planning, and diving skills than most Koh Tao Diving Spots. Divers who are not fully prepared may find it more challenging than expected. If you’re new to diving, it’s worth taking your time to understand what to expect. Nava Scuba Diving breaks down the key points to help ensure a safe and enjoyable Scuba Diving Experience.

1. Sail Rock Is Much Further Away Than Other Dive Sites

Sail Rock is located about 25 kilometers from Koh Tao, with boat travel taking roughly 90-120 minutes one way, depending on sea conditions. This means diving here is not a quick trip but a long open-sea journey that requires good time management and physical readiness.

2. The Diving Trip takes up your whole day

A typical Sail Rock trip can last up to 8 hours, including boat travel, diving sessions, and surface intervals. Divers should prepare in advance with proper rest and essential gear for spending long hours offshore.

3. Poor Conditions Can Affect the Entire Trip

As an open-sea site far from the island, Sail Rock does not allow for easy changes to nearby dive locations. If conditions such as strong currents or low visibility arise, the dive may be less enjoyable. Careful planning and weather checks are essential.

4. Depth and Currents Is More Suited to Experienced Divers

With depths reaching up to 40 meters and currents flowing around the rock, Sail Rock is better suited for divers with strong buoyancy control and Advanced Open Water training or deep-diving experience. New divers may find the conditions demanding.

5. Sail Rock Thailand is Not Beginner-Friendly / First-Time Divers

For those interested in Discover Scuba Diving or starting their first PADI Open Water course, Sail Rock is not the best place to begin. Depth and currents make buoyancy control critical. Starting at calmer Koh Tao Diving Spots such as White Rock or Chumphon Pinnacle offers a safer and more comfortable introduction before progressing to sites like Sail Rock, which is often regarded as the Best Dive Site Koh Tao for experienced divers.

Do you really need to travel to Sail Rock to see whale sharks?

Many divers travel all the way from Koh Tao to Sail Rock, thinking it’s the only place to see whale sharks, but the truth is, you don’t always need to go that far. Chumphon Pinnacle often offers whale shark encounters just as frequently, and sometimes even more easily. Still, sightings depend on factors like season, currents, and weather, so nothing can be guaranteed. To make sure your trip is both worthwhile and safe, you can consult Nava Scuba Diving in advance to choose the best timing and dive site for your Scuba Diving Experience around Koh Tao.
