The attractions of Huai Yang

Huai Yang Waterfall

A small waterfall at the main visitor center area, accessible by a signposted and well maintained circular trail. The trail is on the first five tiers, 5th tier is 700 m from the start of the trail. Ranger guidance needed to visit the last two tiers further upstream because they are too steep and the way to get there is through some rock climbing. It costs up to 300 Baht for a few hours of ranger guidance.

The 4th tier of Huai Yang Waterfall

There are ponds on some tiers full of fish swimming towards people in hope to get fish-food. It is possible to buy fish-food next to the restaurant.

Khao Lan Waterfall

Khao Lan is the most impressive of the falls in the park if there is enough water flow. Located south from the main visitor center area in Thub Sa Kae District, this several tier waterfall is around 14 km from highway 14. The water from one of the tiers drops from a 50 m high cliff. This waterfall is worth a visit during the rainy season only. It is possible to swim on top level.

There is a visitor center and camping site near the waterfall, no tents available for rent. There are no restaurants nearby.

Khao On Waterfall

A nine tier cascading waterfall 44 km south from the main visitor center in Bang Saphan District.

Khao Luang Mountain

There are several mountains and one national park in Thailand all named Khao Luang, so it is good to not mix up this mountain with others. Khao Luang Mountain in Huai Yang National Park is accessible for visitors only in guidance with rangers. It takes nearly 5 hours to reach the peak, an overnight stay at the summit is required. The mountain summit has a great view over surrounding areas, hiking there may give an opportunity to see some mammals which are not common around the visitor center area. In case of hiking there guests need to have all necessary equipment with them and carry it to the top.
