Testimonials
Sail Rock is renowned for its diverse underwater topography, offering depths ranging from shallow areas around 5 meters to deeper sections reaching up to 40 meters. While the site is accessible to Open Water certified divers, it’s essential to be comfortable with open-water conditions and potential currents. Beginners should dive with experienced guides and remain within their certification limits to ensure safety and enjoyment.
The “Chimney” is a vertical swim-through tunnel within Sail Rock, starting at approximately 18 meters and exiting around 6 meters. It’s a highlight for many divers, offering a unique experience as you ascend through the rock formation. Divers attempting the Chimney should have good buoyancy control and be comfortable in confined spaces. Always follow your guide’s instructions when navigating this feature.
Sail Rock boasts a rich biodiversity. Divers often encounter large schools of barracuda, trevally, and batfish. The site is also home to groupers, moray eels, and various species of nudibranchs. During certain times of the year, there’s a chance to spot whale sharks, making it a sought-after destination for marine enthusiasts.
The Sail Rock excursion is a full-day trip. We depart from Koh Tao early in the morning and return by mid-afternoon. The boat journey to Sail Rock takes approximately 90 minutes each way, during which you’ll enjoy meals and refreshments onboard.
Absolutely. We provide a light breakfast before departure, lunch between dives, and snacks and drinks throughout the day. If you have specific dietary requirements, please inform us in advance, and we’ll do our best to accommodate you.
Ensure you’re well-rested and hydrated before the trip. Bring your certification card, logbook, swimwear, towel, sunscreen, and any personal items you might need. If you haven’t dived recently, consider a refresher dive to reacquaint yourself with diving skills and equipment.
Yes, all necessary scuba equipment is included in the trip. This comprises your BCD, regulator, wetsuit, mask, fins, tank, and weights. If you have personal gear, you’re welcome to use it, and our team will assist with setup and checks.
Yes, we offer Enriched Air Nitrox for certified divers. Diving with Nitrox can extend your bottom time and reduce nitrogen absorption, especially beneficial for deeper dives like those at Sail Rock. Please let us know in advance if you’d like to use Nitrox, as it requires additional preparation.
Booking your Sail Rock dive adventure is straightforward. You can reserve your spot directly through our website, contact us via email or phone, or visit our dive shop in person on Koh Tao. We recommend booking in advance to secure your place, especially during peak seasons.
Sail Rock is diveable year-round, but conditions are generally optimal between May and September. During this period, the Gulf of Thailand experiences calmer seas and better visibility, enhancing the overall diving experience. However, marine life sightings, including whale sharks, can occur outside this window, so it’s always a good idea to check with local dive centers for current conditions.
