Thanaratna Waterfall is a small natural waterfall located in Noen Hom Subdistrict, Mueang District, Prachinburi Province. Although it is not as grand as the major waterfalls in Khao Yai National Park, its charm lies in its easy accessibility. The waterfall is only 100 meters from Highway No. 3077 (Noen Hom–Khao Yai Road) at kilometer 16, and about 25 kilometers from downtown Prachinburi. This makes it a popular destination for those who want to experience nature without a long trek or lengthy travel.

 

The waterfall is formed by a series of rock rapids along the valley of the Khao Yai mountain range. Water is most abundant during the rainy season from June to October, when the falls flow strongly, creating a cool mist. In the dry and cool seasons, the flow decreases and sometimes dries up, but the shaded forest and tranquil surroundings still provide a refreshing atmosphere, ideal for picnics and relaxation.

 

For adventure seekers, Thanaratna Waterfall offers more than just scenery. Following the stream further leads to a cliff about 25 meters high, which is a popular spot for rappelling. Some sections are very steep, with angles of 70–90 degrees, making it a thrilling activity. However, visitors are strongly advised to join with experienced guides and proper safety equipment due to slippery rocks and moss.

 

In addition to rappelling, there is a trekking route of about 4.5 kilometers connecting to Wang Bon Reservoir. Along the way, trekkers will pass smaller waterfalls and enjoy viewpoints over the lush forest. This route requires stamina and is recommended for those prepared for a more adventurous journey.

 

Popular activities at Thanaratna Waterfall include swimming in the shallow pools, picnicking under the large trees, and photography. Safety should always be considered: avoid swimming in fast-flowing areas, be cautious of slippery surfaces, and supervise children and elderly visitors closely.

 

How to Get There: By private car, drive along Highway 3077 (Noen Hom–Khao Yai Road) to kilometer 16 and follow the sign, then walk about 100 meters to the falls. For public transport, take a minibus or songthaew from downtown Prachinburi toward Khao Yai, get off at kilometer 16, and walk the short distance to the site.

 

The best time to visit Thanaratna Waterfall is during the rainy season (June–October) when the flow is strongest and most beautiful. During the dry season, the falls may have little or no water, but the tranquil forest still makes it a pleasant stopover.

 

Facilities around the waterfall are limited, with only a parking area and resting spots available. There are no official restaurants or accommodations on-site, so visitors should bring their own food and drinks, and take their trash back to preserve the environment. For overnight stays, accommodations in downtown Prachinburi or near Khao Yai National Park are recommended.
