Quick answer: the best Krabi dive sites at a glance

Use this table to shortlist a day. Boat times vary by operator and sea state, so ask each shop for its planned sites and number of dives.

Near Ao Nang and the local islands

Local-island trips suit first-timers and divers rebuilding confidence. Shorter transits mean more time in the water and less time on deck. For shop options and pickup details, read our Ao Nang diving guide. Krabi Scuba Club lists local-island fun dives at ฿3,500 for two dives and Discover Scuba at ฿4,500.

Phi Phi dive sites

Bida Nok, Palong Wall and Shark Point are the names to look for. Phi Phi has plunging limestone walls with soft coral, shallow coral gardens, caves and swim-throughs. Common sightings include green and hawksbill turtles, banded sea snakes, blacktip reef sharks and leopard sharks. Crowds are the trade-off. One experienced diver described Phi Phi as beginner-oriented and busy. That is one opinion, so judge by season and group size. High season runs November to April, when more boats share the sites. Krabi Scuba Club lists Phi Phi fun dives at ฿4,900 and Discover Scuba at ฿5,900.

Southern and offshore sites: Hin Daeng, Hin Muang and Ko Rok

These pinnacles sit roughly 1.5 hours south of Phi Phi, according to a diver who reached them from Koh Lanta. That diver logged Hin Daeng at about 30 m visibility on a drift dive with barracuda. Hin Muang gave 30+ m and a manta on entry. A repeat dive days later brought low visibility and strong current. Treat that as a lesson in variability, not a promise. Ask Krabi operators whether they run these sites from Ao Nang before you plan around them. Ko Rok lies in a protected area, so check fees and rules on the national parks department portal.

Caves and technical diving

Krabi Scuba Club promotes IANTD cave training at Sra Keow and Song Hong, with Klang also named. These are freshwater systems. They are a niche for certified cavern, cave and technical divers, not routine recreational sites. Its technical courses list extended range to 55 m.

How to choose: level, time and budget

Pick the day that fits your certification and patience for travel. Not certified? Book a Discover Scuba session, or start the PADI course route in Krabi. The Open Water Diver course certifies you for later trips. Certified with limited time? Choose a local-island or Phi Phi fun dive. Experienced and flexible? Spend a long day on the southern pinnacles.

Mistakes to avoid

Do not book Phi Phi expecting remote reef, because it is popular and shared. Do not ignore season. Do not skip asking which sites are on the day's itinerary and how many dives are planned, since weather and current change plans. Carry dive insurance, and see Divers Alert Network for safety guidance.

Season and conditions in brief

Dry season, commonly cited as November to April, brings calmer seas and visibility around 15 m with water at 28-30°C. Rainy season, May to October, brings rougher water, visibility of 5-10 m and some cancellations. For detail, see our Krabi diving season guide. Our water temperature guide covers the thermal side.

Costs and logistics in brief

Krabi Scuba Club runs daily departures from Nopparat Thara Pier. Hotel pickup in Ao Nang, lunch, soft drinks and insurance are listed as included. Its snorkeling tours cost ฿1,900 for local islands and ฿2,900 for Phi Phi. Prices and hours checked November 2026, and a single operator is not the market. See typical diving prices for ranges.

Where to base yourself

Ao Nang is the practical base for diving and hiking, though one diver called it very touristy. Krabi Town is quieter and suits an overnight stop after long trips. Songthaews run from Krabi Bus Terminal to Ao Nang. Railay is a beach-first option, covered at the Railay dive center guide.
