The classic Krabi boat day: Tup Island and its sandbar, Chicken Island's rock, Poda Island's beach and Phra Nang. The Tiqets sunrise version leaves before the crowds on a vintage boat, so you see the same islands with the light and the calm water to yourself.
The Hong Islands have a hidden lagoon, white beaches and some of the clearest water off Krabi. A day trip by speedboat from Ao Nang reaches them in about 45 minutes, with snorkelling, lunch and hotel pickup, and is one of the most rewarding day tours in the province.
A full day by speedboat from Ao Nang to Maya Bay, Pileh Lagoon, Viking Cave, Monkey Beach and Phi Phi Don, with lunch, snorkelling and hotel pickup. Maya Bay reopens each October after its closed season, so November is a good month for it.

A peninsula cut off from the mainland by limestone cliffs, so the only way in is by boat. Railay is Krabi's signature beach scene: climbers, kayakers and sunset-watchers on sand that looks like a postcard. A Viator sunset cruise passes by Railay and stops at Phra Nang, Poda and Tup.
6.5 hours (sunset cruise) or a full day on the sand$$Book on Viator → Often called the best beach in Krabi: a crescent of fine sand under tall cliffs on the Railay peninsula, with a sea cave shrine at one end. Tiqets sells a sunset longtail tour with night snorkelling here.

A forest monastery with a staircase up a limestone peak, huge golden Buddhas at the summit and a view across Krabi. Tiqets sells a full-day tour that pairs it with the Emerald Pool and hot springs.
2 hours (9.5 hours with the full-day tour)$$Tickets on Tiqets → A jungle reserve inland from Krabi with a clear green pool, forest trails and a hot spring stream you can soak in. A half-day Viator tour from Ao Nang combines the Emerald Pool and the Namtok Ron hot spring waterfall.
Paddle through mangrove channels and between limestone cliffs at Ao Thalane, one of the most atmospheric kayaking spots in Krabi. Tiqets lists a four-and-a-half-hour sunset kayak tour with a BBQ dinner.
Railay's limestone cliffs are among the best-known climbing walls in Asia. A beginner half-day course from Ao Nang takes four hours with guides, gear and park fees, and no experience is needed.
