We all know Krabi for its beautiful beaches and coral reefs, but if you're looking for something greener, here are seven ways to discover Krabi's greener side.

1. Take a walk through Tha Pom Khlong Song Nam, a tidal mangrove forest on the edge of the Andaman Sea. As you walk inland from the coast, the water changes from brackish saltwater to crystal-clear freshwater. The trees lining the banks of the estuary are camphor trees, known locally as "lumpi" trees. They have adapted to the mixture of salt and freshwater by growing their roots upwards, revealing a gnarled root system above ground – a truly fairytale landscape.

2. Conquer your fear of heights at Tree Top Adventure Park in Ao Leuk. This high ropes course is one of the most creative I've ever seen, utilizing the trees and surrounding cliffs for a system of rope bridges, high ropes courses, and zip lines. Numerous tricky obstacles await you, including a rope bridge you have to cross on a bicycle, a flying broomstick, and even a flying skateboard.

3. Visit Koh Klang, a small Muslim enclave just a 5-minute boat ride from Krabi Town, yet like another world. In this peaceful, rural community, locals will show you how to dig for shellfish at low tide, and with a bit of luck, they might even take you along to inspect their fish traps and find something for lunch.

4. Enjoy lunch at one of Koh Klang's floating fish restaurants. The fish and lobsters caught in traps are displayed in floating tanks for guests to choose from.

5. Take a kayak tour through the dense mangroves of Koh Klang and stop along the way to explore a large cave in the flank of a limestone mountain, which was once used by Japanese troops as a hiding place from the Allies during the war.

6. Stroll through Khao Nor Juji, one of the last untouched rainforest areas in Thailand. It is famous for the diversity and density of its birdlife, as well as its clear freshwater pools, including the famous Emerald Pool, whose color comes from lime deposits.

7. Treat yourself to a relaxing bath and massage at the Warareek Hot Springs Spa near Klongtom. Treatments combine hydrotherapy and traditional Thai massage and typically begin with a body scrub before you soak in the 38 to 41-degree Celsius thermal pools. After your bath, you can unwind in a thatched cabana overlooking the valley with a soothing 90-minute Thai massage.

Ecotourism tours are offered throughout Thailand. This initiative of the Thai Ecotourism and Adventure Travel Association (TEATA) is supported by the Thai Ministry of Tourism. The Krabi tour can be booked with Friends of Nature.
