Scuba Diving in Krabi: Ultimate Guide to Dive Sites, Seasons & Adventures

Krabi has dozens of excellent dive sites, but it’s best to focus on those that offer the underwater experiences you’re looking for.

Day 1 – Ao Nang to Phi Phi / Koh Bida

• Start early: Depart ~7:00 am.
• Morning dive: First dive at Koh Bida Nok or Hin Bida.
• Afternoon dive: Second dive at another nearby site.
• Focus: Sharks, schools of reef fish, and vibrant corals.
• Return: Late afternoon, unwind in Ao Nang.

Day 2 – Koh Haa Lagoon & Chimneys

• Full-day dive trip: Two dives at Koh Haa (Lagoon + Chimneys)
• Overnight stay: Ao Nang or Koh Lanta.
• Focus: Coral gardens, swim-throughs, and macro photography.

Tip: One of the best things to do here is capture the light in the lagoon and tiny details in chimneys.

Day 3 – Hin Bida & Phi Phi Sites

• Select two dive sites: Hin Bida and Phi Phi reef areas.
• Transfers: Coordinate boats or roads for smooth travel.
• Focus: Leopard sharks, reef life, and underwater photography.

Tip: Early dives give better chances for wildlife; avoid midday crowds.

Day 4 – Hin Daeng & Hin Muang

• Full-day advanced dive trip: Pinnacle dives with mantas, soft corals, and pelagics.
• Focus: Wide-angle photography, mantas if in season.

Tip: Respect safety pacing; arrange heavy dives and include rest between dives.

Day 5 – King Cruiser Wreck & Koh Lanta Selection

• Morning: King Cruiser Wreck dive – explore exterior first, interiors later.
• Afternoon: Koh Lanta local sites – turtles, small wrecks, and coral gardens.

Tip: Light dives in the afternoon help recovery and still offer photography opportunities.

• Book Early (Nov-Apr): It is the high season, and the diving slots, good guides, nitrox tanks, and camera gear have been sold out early. Reserve before you land.
• Gear Rentals: Nitrox bottles and camera housings have been known to sell out quickly, so grab them as soon as you can.
• Be Flexible (May–Oct): Weather can change quickly. Check cancellation policies carefully and be ready to adjust plans within 72 hours.

1. Money and Timing: You’ll pay per day or per trip, which will cover boat, tank, weights, and typically lunch. Prices float depending on the month and operator, so get a current quote. From November to April, book early or risk missing the best boats.
2. What’s Included: A Boat ride, two dives, tanks, weights, a real safety briefing, and a meal. Transfers from Ao Nang are a common extra. Check and confirm if you’ll have to cough up more for rental gear or park entry fees.
3. Equipment, Nitrox, and Cameras:     

• Full rental kits, jackets, regs, wetsuits, and masks/fins are usually on offer. Do yourself a favour and ask how old the gear is and when it was last serviced.
• Nitrox is available at many outfits, but not all; reserve early and don’t rely on walk-in luck.
• Camera rentals – if you need them, typically are in tight supply during the high months. Book these as soon as you have travel dates; better yet, bring your own.

1. Insurance & Medicals:     

• Don’t skip dive insurance that handles emergencies and evacuation. Operators will ask you to fill out a medical self-check. Sometimes, request a doctor’s note if you’ve had past trouble or are over a certain age.
• Never assume you can dive advanced sites without showing recent cards and logbook entries.
