Diving Krabi & Railay – bays, walls, and Phi Phi day trips
Krabi’s limestone coastline puts you close to the Phi Phi National Park, Shark Point marine sanctuary, and mellow inshore reefs. Most shops are based around Ao Nang or Railay and run daily boats out to the islands.Expect relaxed 3-dive day trips, lush walls, and plenty of macro. Peak season runs from November–April when seas are calm, but year-round diving is still possible with flexible scheduling.
Best season
Dry season (Nov–Apr) brings calmer seas and clearer visibility for the Phi Phi marine park.
Skill mix
Beginner-friendly fringing reefs plus intermediate walls near Bida, Shark Point, and the King Cruiser wreck.
Trip format
Full-day boats with 2–3 dives, breakfast + lunch onboard, hotel pickup from Ao Nang / Railay.
Planning tips
