Roctopus Dive at a glance

Roctopus Dive opened in 2011 and sits on Sairee Beach, the west-coast strip with most of the island's dive shops. A 2018 profile counted about 15 instructors. Figures in the list come from that period, so ask the school for its 2026 numbers before you pay a deposit.

• Location: Sairee Beach, Koh Tao
• Main agency: RAID, with SSI offered and PADI on request
• Open Water length: 4 days
• Class size listed: 4 students per instructor
• Facilities: purpose-built pool for confined training and air-conditioned classrooms
• Course range: Open Water, Advanced, Rescue Diver, Divemaster, Instructor and specialties

Who Roctopus suits and who should look elsewhere

Roctopus fits beginners who prefer small groups. A pool matters if you are nervous in open water, because confined skills are easier to learn in calm, flat conditions. Divers who want to go pro will also find Divemaster and Instructor programs on the course list. Travelers with a strict agency requirement should ask early, since RAID is the default. If you want a resort with its own large accommodation complex, look at Bans Diving Resort. If you want a PADI-first school with a pool and bar, Davy Jones Locker is another Sairee Beach option. Budget-sensitive divers should compare several quotes, using our guide to all Koh Tao dive schools as a starting point.

Roctopus Koh Tao Open Water course: what to expect

Roctopus lists its Open Water course at 4 days, with 4 students per instructor. Expect three parts. Theory covers a couple of hours of video, discussion and quizzes, ending with an exam. Confined water sessions teach you to use your kit in the pool. Four open water dives follow, and the school dives different sites depending on conditions. Daily start times vary, so ask for your exact schedule at booking. Short on time? Finish the eLearning theory before you arrive. That frees more of your trip for the sea, which matters if you only have 5 or 6 days on the island.

RAID, SSI or PADI: choosing an agency

Agency choice is the most important decision at Roctopus. RAID is the main system, SSI is offered, and PADI can be arranged on request. All three follow the same general training framework. Ask whether your card will suit the next course you plan. You can usually switch agencies later, for example SSI Open Water followed by PADI Advanced. Check recognition on each agency's own site, such as the SSI dive center locator. Online theory pricing differs by agency. Some SSI schools include it free, so ask what the eLearning costs under RAID.

Cost: what to ask before you pay

A 2018 listing put the Roctopus Open Water course at ฿11,100. Treat that as historical only. Koh Tao schools reportedly agreed a minimum Open Water price that year, but 2026 rates may differ, so get a written quote from the school. Then ask exactly what the price covers.

• Course fee and certification card or materials fee
• Whether eLearning or a manual is included
• Accommodation included, and for how many nights
• Gear rental, and whether it is part of the fee
• Dive insurance and any extra dives after the course
• Price tell: a quote far below other schools often means larger classes or no pool
• Price tell: a vague answer on students per instructor
• Mistake to avoid: booking the cheapest quote without asking about class size and confined-water facilities

Getting to Sairee Beach and Roctopus

Koh Tao has no airport, so you arrive by boat. Chumphon is the closest mainland port. Surat Thani works too, and ferries also run from Koh Samui and Koh Phangan. Boats dock at Mae Haad, the main town and ferry port. Sairee Beach is about 2 km away, roughly a 15-minute walk or a short taxi ride. From Bangkok, bus and ferry combination tickets take about 9 hours on a morning departure. Evening departures take about 12 hours. Lomprayah, the fastest operator, crosses from Chumphon in around 1½ hours. Baggage is capped at 20 kg (about 44 lb), with excess charged at ฿20 per kg. Return boats from Koh Tao leave in the morning and afternoon, and you reach Bangkok after dark. Do not book a same-night onward flight. Check current timetables on the operators' sites.

Where to stay

Many schools bundle a bed with the course, so ask whether Roctopus includes accommodation in its quote. Ask what room type it covers and how much an upgrade costs. A 2018 profile mentioned a link with Good Dream Hotel, but ask the school whether it still applies. Sairee Beach puts you within walking distance of your classroom and the dive shops. It is also the liveliest stretch for restaurants and bars. Mae Haad, near the pier, is quieter and handy for early boats. If you take a Sairee dorm, 4 days of early starts leave little time for nightlife anyway.

Roctopus vs. other Koh Tao schools

Class sizes and prices below come from 2018 listings and may have changed. Use the table as a question list, not a final answer. Crystal Dive publishes its own details on its official site. For a smaller-school angle, see Black Turtle Diving. Simple Life Divers has its own page. DPM Diving does too.

Dive sites and seasons

Roctopus runs trips to Sail Rock, a site well known in the Gulf of Thailand. Ask which certification level it requires, since it is a deeper outing than a first-day training dive. The Gulf can be dived all year. Operators describe May through September as the best window. Conditions change from year to year, so treat that as a pattern, not a promise. The Andaman Sea on the other coast peaks from October through April, which is why many travelers pair Koh Tao with the Gulf season.

Safety, insurance and medical readiness

Every course starts with a medical questionnaire. Answer it honestly, because a yes on certain conditions means a doctor's sign-off before you dive. DAN, the Divers Alert Network, publishes guidance on fitness to dive and dive insurance. Buy cover that explicitly includes diving. Koh Tao is a small island, so ask Roctopus about its emergency plan and the nearest medical facility. Do not fly within the surface interval your agency advises after your last dive.
