Limestone cliffs above, Andaman reefs below: base in Ao Nang and Railay
Updated Jan 23, 2026 • 18 sources
Overview
Krabi's Ao Nang and Railay sit on Thailand's Andaman coast, framed by limestone karsts and close to the Hat Noppharat Thara - Mu Ko Phi Phi National Park. From this base you can dive or snorkel the Phi Phi Islands' walls and reefs on easy day boats, then be back for sunset on Railay. Conditions are warm year-round, with the calmest seas and best visibility usually in the dry season from November to April. Krabi also works as a hub: add Koh Hong for lagoons, or transfer south to Koh Lanta for Koh Haa and advanced sites like Hin Daeng and Hin Muang. Above water, the region blends world-class rock climbing, mangrove kayaking, temples, and hot springs, so mixed groups can build a trip that keeps everyone busy.
Stay in Ao Nang for logistics, or Railay for a car-free beach vibe, and move between them by longtail boat.
Easy day trips into Hat Noppharat Thara - Mu Ko Phi Phi National Park and Than Bok Khorani National Park (Koh Hong).
Divers can do Phi Phi day boats while non-divers climb, kayak mangroves, or hit hot springs, then regroup for sunset and street food.
Use Krabi as a gateway to Koh Lanta for Koh Haa, and advanced Andaman pinnacles like Hin Daeng and Hin Muang in season.
