There is plenty to see and do in this province, and it is easy to lose yourself here for more than a month as you hop from island to island and beach to beach. Popular activities are sea kayaking and canoeing, whilst diving and snorkelling are always popular in Thailand's crystal clear waters.
Ao Nang is the closest beach to Krabi Town. This area is mainly occupied by large, upmarket beach resorts. You can hire a sea kayak or long-tail boat and explore the uninhabited island of Koh Hong.
Just 6 kilometres away from Ao Nang is the well loved are much talked about Hat Noppharat Thara, which is a famous 3 kilometer long white sandy beach, perfect for taking it easy and soaking up some rays. Elephant trekking is popular in this area, while the hot springs at Khlong Thom are a good place to ease aching muscles. Whilst there, check out the informative Wat Khlong Thom museum.
Railay is perhaps the prettiest beach in this area. This is a great place for rock climbing, and the sunsets at Hat Rai Leh West are spectacular.
There are some interesting limestone cliffs to explore. Tham Phra Nang is named Princess Cave after a local legend. The cave is hidden in the lagoon of Sa Phra Nang (Holy Princess Pool). Climb the cliff top for spectacular views.
Nearby, Tham Phra Nang Nai (Inner Princess Cave) is a series of illuminated caverns of high beauty. A feature point is the unusual 'stone waterfall', which is made of sparkling golden quartz.
Khao Phanom Bencha National Park consists of 50 square kilometres of virgin rainforest and a whole host of pretty waterfalls including Nam Tok Huay To, Nam Tok Huay Sadeh and Nam Tok Khlong Haeng and it is possible to swim in most of the waterfalls. The park is also home to the cave of Tham Khao Pheung, which contains stunning shimmering mineral stalactites and stalagmites.
Another area of natural beauty is the large Than Bok Khorani National Park, where caving is the main activity. Caves of interest here include Tham Hua Kalok, Tham Lawt and Tham Sa Yuan Thong. If you need a break from the beach, there are many interesting temples in the area to explore. Look out for the monastery of Wat Sai Thai, which is a particularly auspicious place and very interesting around Buddhist holidays.
There are many places to get a good meal, and of course seafood is top of the menu. Barbecues can be found all along the beach and western food is widely available. If you are looking to save a few baht, the night markets are generally the cheapest places to eat and these are the best places to find tasty, authentic Thai food.
