Quick Answer: What a Phuket Liveaboard Is and When It Runs

Most operators sell a Phuket liveaboard as a hotel pickup, an evening boarding and an overnight cruise to the dive sites. Some piers sit about 1 to 1.5 hours from Phuket International Airport (HKT), so allow for that transfer. Similan National Park is open for diving from about mid-October to mid-May. Park tourism closures in recent years ran from May 16 to October 14 in 2025. Treat that as a pattern, not as this year's dates, and read the current notice from the Department of National Parks. For the country-wide picture, start with our Thailand liveaboard overview.

Liveaboard or Day Trip from Phuket?

A day trip works when you want one offshore day and a hotel bed at night. A liveaboard works when the dive sites are the point of the trip. Typical liveaboard schedules run up to 4 dives a day, while a day format may offer as few as 2 dives. Use the table to match the format to your own limits.

Season Guide: High-Season Routes vs Low-Season Phuket Trips

High season gives you the famous northern sites: Similan Islands, Koh Bon, Koh Tachai and Richelieu Rock. Some boats also run south to Hin Daeng and Hin Muang. From May to October the parks are closed and Similan and Surin entry is not possible. Low-season boats dive around Phi Phi, Racha, Shark Point, Anemone Reef, Koh Doc Mai and the King Cruiser Wreck. Operators report that marine life stays present all year, including manta rays around Racha Noi. Those sightings are never guaranteed. Visibility and sea state vary, and cloudier skies can cut light underwater.

Routes and Trip Lengths: Who Each Suits

Short trips of 2 or 3 nights suit divers testing the format. A 4-night northern trip is the classic choice. One example itinerary lists 14 dives across the Similans, Koh Bon, Koh Tachai and Richelieu Rock. Our Similan liveaboard guide covers those sites in depth. A 3-night southern example lists 11 dives at Hin Daeng, Hin Muang, Koh Haa and Phi Phi. Joining the two makes a 7-night combo with about 25 dives. Read our Surin Islands liveaboard page if Richelieu Rock is your priority. Myanmar trips run longer, so check visa and entry rules first. The Mergui Archipelago: Access, Season & Liveaboard Options is the extended option. Pair it with Burma Banks shark dives only if you have the days to spare.

What a Typical Day Aboard Looks Like

Treat any posted schedule as an example. Captains choose sites daily from weather, diver experience and group requests. A common rhythm starts with a 07:00 wake-up and runs to a dusk or night dive. Most Similan boats serve fruit between dives, with coffee and tea available all day. Water runs about 79 to 84°F (26 to 29°C), and a 3 mm wetsuit is the usual recommendation.

• 07:00: wake-up, coffee and briefing, then the early dive
• 08:30: breakfast
• 11:00: boat relocates for the second dive
• 12:30: lunch
• 15:00: third dive
• 17:30 to 19:00: dusk or night dive
• 20:00: dinner

Leaving from Phuket or Khao Lak: Pickups, Piers and Transfers

Most Similan boats leave in the evening. Hotel pickups in Phuket start around 15:00 on one operator's schedule. Another Chalong-based itinerary lists an 18:00 pickup and a 20:00 departure, with a light meal served while cruising overnight. Khao Lak pickups start around 18:00. Some boats are based in Khao Lak, so ask which pier your boat uses before you pick a hotel. Shorter 2 or 3 day trips can leave in the morning. On a 4-day example itinerary, you return to Phuket and your hotel at about 18:00 on the last day.

What the Price Should Include (and Common Extras)

Compare quotes like for like. Prices and rates below were checked November 2026. Park fees are the clearest figure. One operator's schedule lists ฿500 for entry to the Similans, Richelieu Rock and Surin, plus ฿200 per diver per day. Park agencies set those fees and can change them without notice. The same schedule lists Nitrox at ฿200, a 15-liter tank at ฿300 and a torch at ฿150 per dive. Treat those as examples, not as a universal rate card. Our Thailand liveaboard comparison lines up boats by tier.

• Usually included: cabin, meals, tanks, weights, dive guide, hotel transfer
• Often extra: park fees, equipment rental, Nitrox, torch hire, 15-liter tanks
• Ask about: insurance, tips, alcohol and transfers from other pickup areas

Weather, Cancellations and a Backup Plan

Boats follow the sea, not your itinerary. Operators reserve the right to cancel or alter a trip for safety. Ask who makes the final weather call and how close to departure it happens. Ask whether you get a refund, a credit or an alternative route. Keep a spare night in Phuket before you board. Keep a buffer after the last dive too. Allow the standard no-fly gap after your final dive, and confirm the exact interval with your dive insurer, operator or Divers Alert Network. Skipping that buffer is a common planning mistake.

Who Should Skip It, or Pick Another Option

Skip a liveaboard if you are new, rusty or prone to seasickness. Skip it if you cannot hold flexible dates. Anyone out of the water for a while should book a refresher course before boarding. Low-season liveaboards can offer Open Water courses, but that is no longer possible inside Similan National Park. A day trip or a Phuket-based dive plan is the safer fit for nervous divers.
