Every Phuket Dive Site Sorted by the Pier Your Boat Leaves From

Before you pick the shop, pick the pier

From Chalong Pier at 07:45, the first wave of dive boats is already pulling away toward the Racha Islands. A few kilometres north, Ao Por sends a smaller fleet east toward Phang Nga. Rawai and Ao Yon launch longtails toward the reef off Koh Hae. If you think you're booking a dive trip in Phuket, what you're really doing is booking a pier — because the pier decides your transit time, your operator pool, and more often than not the species you'll see underwater. Most divers only figure that out after their second or third trip.

Phuket has four active departure points for scuba day trips and one for liveaboards. This is where each one goes, how long the boat ride actually takes, and what the 2026 prices look like. Transit hours come from operator schedules; park fees are charged per day at the pier, in cash.

Chalong Pier — the main hub (about 90% of day trips)

Chalong is the default answer for a reason. Every big operator — Sunrise Divers, Aussie Divers, Sea Bees, Phuket Dive Tours, Love Diving Phuket, Indepth, Aum Scuba — runs at least one route out of Chalong. A typical schedule: hotel pickup between 06:30 and 07:30, pier check-in, boat boarding around 08:00, first dive at a Phi Phi wall or a Racha site by 10:15. You're usually back at the dock by 18:30 and in the hotel shower by 19:30. If your shop is quoting a Phi Phi or Racha trip, this is the pier.

Six sites dominate the Chalong day-trip map.

• Racha Yai — the most-run site on the whole island. Roughly 20 nautical miles south; transit 1h20m to 1h45m. Easy sloping reef on the east side, protected from southwest monsoon swell. Great for open-water refreshers, first fun dives, and wide-angle photography. Most dives stay in the 18–22m range.
• Racha Noi — eight miles further south than Racha Yai. Visibility routinely 25m+, often pushing 40m in the shoulder months. Bigger boulders, bigger fish, stronger current. South Tip and Banana Bay are the manta plays — oceanic mantas show up with rough regularity between February and April.
• Phi Phi — two dives at Phi Phi Le walls (Hin Bida, Maya Corner, Palong Wall) plus a third at Koh Doc Mai, Shark Point, or Anemone Reef depending on current. You'll pay the National Park fee at the pier before boarding: 400 THB park entry plus 200 THB scuba surcharge — 600 THB per diver per day, in cash.
• Shark Point (Hin Musang) — the limestone pinnacle cluster about two hours east of Phuket. Soft coral fans, leopard sharks on the sand in the 18–22m range, occasional whale-shark sightings in April. Current-driven; not a gentle dive and not a site for your fourth-ever fun dive.
• Anemone Reef — the submerged pinnacle roughly 800m from Shark Point, top at about 5m and base at 26m. Named for the carpet of purple and pink anemones that covers the upper slope. Leopard sharks, giant moray, schools of jack and barracuda, and a depressing amount of fishing line snagged in the soft coral every time I've dived it.
• King Cruiser Wreck — an 85-metre car ferry that sank in 1997 between Phuket and Phi Phi after hitting Anemone Reef. Top deck at 16m, hull resting on the sand at 32m. Advanced Open Water plus 20 logged dives is the minimum at most shops; penetration is closed by every reputable operator because the structure is collapsing. Best as the second dive of a Shark Point / King Cruiser combo run.
• Koh Doc Mai — "Flower Island," a 250-metre limestone pinnacle about 15 km east-southeast of Chalong, transit roughly 55 minutes. The east side is a sheer wall from the surface down past 25m into a sandy slope below 40m. Caverns at 14m on the southern end, easy for any diver comfortable in an overhead. Known for nudibranchs — I've logged more than ten species on a single dive here — and for seahorses if you slow down enough to find them.

Most Chalong operators bundle these into four standard day trips: Racha Yai only (beginner-friendly, cheapest), Racha Yai plus Racha Noi (3 dives, harder current, manta chance in season), Phi Phi plus one pinnacle (3 dives, park fees extra), and King Cruiser plus Shark Point plus Koh Doc Mai (advanced only, best February to April). If you're new to Phuket day-trip diving the middle two packages are the sweet spot.

Ao Por Pier — the eastern back door

Ao Por sits on the northeast coast of Phuket, roughly 40 minutes by road from Patong or Kata. It's the pier of choice for trips heading into Phang Nga Bay and for any operator whose clients sleep on the north side of the island. A handful of shops use it — All4Diving, Aloha, some of the smaller Rawai-based outfits — when the southwest monsoon makes a Chalong launch miserable.

Ao Por is also where most Phuket liveaboards pushing off toward Phi Phi or the east bay start, if the route is heavy on Krabi-side sites. For day divers, the sites reached from Ao Por are roughly the same ones as Chalong — Shark Point, Anemone, Koh Doc Mai. The pier just cuts 25–30 minutes off the transit for the eastern cluster and adds 25 minutes of minivan time on land. It's mostly worth it for guests in Mai Khao, Bang Tao, or Surin, where a Chalong pickup eats 90 minutes each way.

Rawai Pier and beach launches — the longtail circuit

Rawai is not a serious scuba pier — it's where the longtail captains live. A small number of shops run shore-based or longtail trips to Koh Hae (Coral Island), the reef off Promthep, and the Ko Lone / Ko Bon fringing reef for introductory dives and discover-scuba sessions. If you've been quoted a 2,500 THB "Phuket scuba day" this is where it's launching from. Max depth typically 12–15m, often a single dive, and the shops here rarely touch the Racha or Phi Phi circuit. Fine for a first try if your travel companion is snorkelling alongside, but not where certified divers should spend the day.

Rassada / Deep Sea Port — the liveaboard door

Rassada handles bigger boats and cruise-ferry traffic. For divers this mostly means liveaboards — Similans, Surin, Burma Banks. A few day boats occasionally shift there in late-season swell when Chalong is rougher than the east coast. Not a booking you'd make on purpose; if your shop moves you to Rassada for a day, the reason is almost always the weather.

Port × site × season — the quick matrix

Conditions at the same site shift dramatically by month. This is how I'd read the 2026 season if I were picking a single week to fly for:

Site	Best pier	Nov–Jan	Feb–Apr	May–Oct (green)
Racha Yai	Chalong	Good, 20m viz	Excellent, 25–30m	East side still divable
Racha Noi	Chalong	Good, strong fish	Manta peak, 30m+	Weather-dependent
Phi Phi	Chalong or Ao Por	Very good	Flat, glass-calm	Viz 10–15m
Shark Point / Anemone	Chalong or Ao Por	Strong current	Leopard sharks on sand	Often cancelled
King Cruiser	Chalong	Advanced only	Best visibility window	Closed most days
Koh Doc Mai	Chalong	Consistent	Nudibranch peak	Good fallback
Hin Daeng / Hin Muang	Liveaboard only	Liveaboard	Whale shark + oceanic manta	Closed

Note on Hin Daeng and Hin Muang: these pinnacles are around 100 km south of Phuket in Mu Koh Lanta National Park. No regular day-trip operator runs them from Phuket — the transit kills the day. Book a three-day liveaboard out of Chalong or a Koh Lanta shop instead. For help choosing your base, see Phuket vs Koh Tao vs Khao Lak.

What 2026 prices actually look like

Prices I've seen quoted by Chalong operators this season — numbers in Thai baht, per certified diver, two tanks unless noted:

Trip	Dives	Price range 2026	Park fees on top
Racha Yai only	2	2,900 – 3,400	—
Racha Yai + Racha Noi	3	3,800 – 4,500	—
Phi Phi + one pinnacle	3	3,700 – 4,800	600 THB
King Cruiser combo	3	4,200 – 5,500	—
Phang Nga day from Ao Por	2	3,500 – 4,200	variable
Longtail Koh Hae (Rawai)	1–2	1,800 – 2,500	—

Rental gear is typically 500–700 THB on top, and most shops include hotel transfer from Chalong, Kata, or Patong free of charge but charge 300–500 THB extra for pickups from Mai Khao, Bang Tao, or Surin (all over an hour from Chalong). A 10% discount for three-day packages is normal; shops will pretend it's a "season deal" but it's the standard house rate. For the full seasonal picture see the Phuket diving calendar.

What the last month has looked like

April 2026 reports out of the Chalong boats have been about what you'd expect for mid-shoulder: Racha Noi visibility holding 25–30m on the east side, Shark Point still fishing current-heavy, and leopard-shark sightings steady on the deeper Anemone approach. A couple of the longer-running day shops have noted good plankton bloom signals around Racha Noi's South Tip — historically that correlates with manta encounters through the end of April. Phi Phi has been calm enough that operators are back to running the Hin Bida / Palong Wall triple without weather substitutes. If you're booking for May and your shop offers King Cruiser, take it — the window closes fast once the southwest swell picks up. For context on what you'll actually see, cross-check the Phuket marine life breakdown.

One thing I'd tell a friend

Don't book the first dive shop a taxi driver recommends. Pick the pier first. If you're staying in Kata, Karon, Patong, or Chalong itself, your shop should launch from Chalong — anything else is selling you 45 extra minutes in a minivan. If you're up in Mai Khao or Bang Tao, ask whether they have an Ao Por option; on an east-wind day that's the better ride. And if your target species is a manta, only one island matters — Racha Noi's South Tip, February through April, out of Chalong, sat on the bow at first light. Book that one separately from a general package if you have to. For a first-timer's perspective on how the day actually unfolds, the first dive in Phuket write-up is a useful gut-check.
