About 70% of Koh Kood is covered by ancient tropical rainforest with Klong Chao Waterfall or (in Thai) Nam Tok Khlong Chao in the center. The Klong Chao Waterfall flows throughout the year and offers a nice swimming spot.
It’s actually quite a famous waterfall as His Majesty King Rama VI visited the waterfall in 1911. He named it Nam Tok Anam Kok to commemorate Ong Chiang Su, a Vietnamese king taking refuge in Thailand in the late 18th century.
The waterfall is easy to reach by motorbike, bicycle, taxi or even by foot. Just follow the signs or rent a kayak and paddle up the Klong Jao River, a short trip but certainly worth it! The entry is close to the point where kayaks can’t go any further up river. Kayaks can be rented at several accommodations along the Khlong Jao River.
The entrance is free and from the road to the waterfall is a short trek through jungle of about 10 minutes with a clear path to follow. Near the wooden sign and exit to the left is a small temple on the right where often monks are meditating.
Many resorts offer trips to the waterfall or can organize a (private) trip. Most package tours include a trip to the waterfall and most of them go there in the afternoon.
The waterfall flows all year round but the best time to visit is from August till January.
No shops around (yet) so it’s recommended to bring some drinks.
