Last updated November 2026: Christmas Point Similan is a granite-boulder drift dive off the north end of Island 9 (Koh Bangu), usually treated as intermediate to advanced. Reported depths run 10–40 m (33–131 ft), and the national park is seasonal. Operators set site access and requirements on the day, so use this page to decide, then compare options across all Similan dive sites.

Christmas Point Similan at a Glance

Christmas Point is a big-boulder drift dive on the northwest corner of Similan Island No. 9 (Koh Bangu). PADI's site page says the name comes from the Christmas tree worms on its rocks. Depth runs 10–40 m (33–131 ft), with the main action at 24–30 m (79–98 ft). Current is moderate to strong, and PADI labels the site advanced only. Figures below are as reported by PADI and local operators, so your dive briefing overrides them.

What the Dive Is Like

Sponsored

A submerged granite ridge runs out from the island. Tides have carved it into tall boulders, crevices, arches and swim-throughs, notably around 25 m (82 ft). Walls carry soft corals, sea fans and giant gorgonians. At about 28 m (92 ft), the Ridge looks out into open blue water where pelagics can pass. Sharks and turtles are listed among common sightings, but nothing here is guaranteed. Boulders double as shelter when the flow picks up. Plan to drift rather than hover, and watch your gauges, because depth builds quickly at sites like this.

Is Christmas Point Right for You?

Treat this as a fit test, not a certification rule. Each operator sets its own requirements, and the briefing makes the final call. One Similan liveaboard program, for example, requires certification to 30 m (98 ft) or an onboard upgrade for Open Water divers. That is a rule of that program, not of every boat. Beginners and newly certified divers should ask for a gentler site instead, or book a Discover Scuba session with a dive center.

  • Certification and logged dives: enough experience to feel relaxed beyond basic Open Water limits.
  • Current: comfortable with drift dives, descending on a line and sheltering behind boulders.
  • Depth: comfortable near 30 m (98 ft), where much of the action sits.
  • Recent diving: a refresher is wise after a long break.
  • Gear: dive computer and exposure suit agreed in advance.

Christmas Point vs North Point and Nearby Sites

North Point sits at the very end of Island 9, close to Christmas Point. Big Blue Diving lists North Point as beginner to advanced with currents weak to strong, while PADI rates Christmas Point advanced. Dive Phuket Today compares North Point's swim-throughs to Elephant Head Rock, Similan Islands Guide. Divers who want stronger current and manta rays look to Koh Bon: Manta Dive Site North of the Similan Islands, which one Similan guide calls an advanced site.

Day Trip or Liveaboard?

Day trips suit divers who want to return to the same hotel. Compare the road transfer, the sea journey, the dive count and the actual sites on the schedule. Liveaboards stack dives over several days and can continue beyond the central group to Koh Tachai: Diving, Snorkeling and Access Rules. From Koh Tachai, Koh Bon lies about one hour north by boat. Richelieu Rock sits in Mu Ko Surin National Park, so park charges on a package may differ from Similan ones.

Tip

Liveaboard programs can set their own rules, such as certification to 30 m (98 ft), so compare each boat's requirements.

When to Go and When the Park Is Closed

Sponsored

PADI lists the Similan season as October to May, with the park closed June to September for the monsoon. One Phuket operator gives North Point as open November to April. Operator calendars can be narrower than park dates, so work to the shorter window. PADI puts best visibility at 15–30 m (49–98 ft) from December to April. Water is reported at 26–30°C (79–86°F) by PADI and about 25°C (77°F) by another Similan guide, so expect warm water and still agree suit hire in advance.

Park Fees, Booking and What to Confirm With Operators

Park fee amounts and who collects them change, so none are quoted here. Check current rates with the Department of National Parks.

Tip

Water at 26–30°C (79–86°F) is warm, but the operator checklist still asks you to confirm suit hire and sizes.

  • Which sites are on the itinerary, and does the boat reach Island 9?
  • Minimum certification and logged dives for each planned dive.
  • Gear hire, including computer, suit and sizes.
  • Guide-to-diver ratio on the boat.
  • Cancellation policy if weather or park rules change the route.

Snorkelers and Non-Divers

Non-divers can join some trips if the operator accepts them. Ask whether the product includes supervised snorkel stops rather than only a seat aboard. A snorkel ticket is not a beginner scuba trip. For gentle water, Donald Duck Bay, Similan Island 8: Snorkeling & Guide on Koh Similan is described as a good place to start, with green turtles. Discover Scuba through a dive center is the route for beginners who want to try diving.

Common Mistakes

Sponsored

Most problems come from planning around stat blocks instead of the day's briefing.

  • Trusting a single "best conditions" figure for current, visibility or season.
  • Booking a day trip without checking it reaches Island 9.
  • Skipping a refresher after a long break from diving.
  • Underestimating how fast depth builds on boulder sites, where 30 m (98 ft) arrives quickly.
  • Assuming the park is open outside the October to May window.

Frequently Asked Questions

Is Similan Island worth visiting?

For certified divers, yes: sites like Christmas Point offer granite boulders, swim-throughs and soft coral walls. Snorkelers have gentler options such as Donald Duck Bay. Visit between October and May, when the park is open.

Can you go to Similan Islands from Phuket?

Operators in Phuket and Khao Lak sell both day trips and liveaboards. Ask whether your boat reaches Island 9 before you book a Christmas Point dive.
