Yong Waterfall National Park is an important protected area with exceptionally high biodiversity in Nakhon Si Thammarat Province. The park is located along the Nakhon Si Thammarat Mountain Range, a significant watershed dividing the Tapi and Trang river basins.

The park’s most prominent attraction is Yong Waterfall, a stunning limestone waterfall that flows powerfully throughout the year and never runs dry. Its steep limestone cliff causes the cascading water to resemble a massive twisted rope hanging down the rock face. At the lowest tier lies a large natural pool, approximately thirty meters wide, filled with clear water that allows visibility all the way to the bottom.

One of the waterfall’s greatest charms is the huge schools of mahseer fish swimming freely and calmly in the pool, creating a rare and memorable experience for visitors who enter the water. The waterfall consists of seven distinct tiers, each offering unique scenery and varying levels of accessibility depending on the trail conditions.

The surrounding area is covered by dense and pristine tropical rainforest, home to large trees such as dipterocarps, takians, and other rare plant species. Beyond the waterfall, the park also features Khao Hmen, the highest peak within the park, attracting adventurous hikers.

Access to the first tier of the waterfall is very convenient, as it is located only a few hundred meters from the parking area and the park headquarters. Well-designed walking paths and wooden bridges cross the streams, providing popular photo spots for visitors.

The climate within the park remains cool and humid throughout the day, creating a refreshing atmosphere that helps visitors relax and unwind. Yong Waterfall National Park is also a popular venue for outdoor activities such as nature study hikes and camping.

The crystal-clear water offers a rare opportunity to observe the fascinating group behavior of mahseer fish, a sight seldom seen in natural settings. A variety of wildlife and colorful bird species continue to inhabit the deeper forest areas, reflecting the park’s successful conservation efforts.

Facilities within the park include a visitor center, parking areas, local shops, and clean restrooms. For those seeking adventure, park rangers are available to guide hikes to higher waterfall tiers and scenic viewpoints.

The best time to visit is from January to July, when the weather is clear and the water flow is ideal. Due to its close proximity to Thung Song town, only a few kilometers away, the park is easily accessible for day trips. Yong Waterfall National Park stands as a proud symbol of natural abundance cherished by the people of Nakhon Si Thammarat.
