The waterfall was formerly known as 'Ton Ploi' before being renamed by Her Majesty Queen Sirikit during a visit in 1988.
It is located at an elevation of approximately 1,100 meters above sea level.
The waterfall is carved into a massive granite rock face, which is the primary geological feature of the Doi Inthanon massif.
The high humidity in this specific micro-climate supports rare orchid species and epiphytic plants growing directly on the cliff-side trees.
Sirithan Waterfall is a powerful multi-tiered cascade situated within the Doi Inthanon National Park in northern Thailand. The waterfall is fed by the Mae Klang River and drops approximately 50 meters over a steep granite cliff face. Visitors access the falls via a paved path leading to a dedicated wooden observation platform that offers a direct view of the main chute. The surrounding area is part of a dense, humid cloud forest ecosystem characterized by moss-covered rocks and ferns. It is one of the more accessible waterfalls within the park boundaries compared to more remote trekking sites. The waterfall maintains a consistent flow year-round due to the high altitude of the mountain range.
The center of the wooden viewing platform provides a straight-on, unobstructed frame of the main cascade.
Wear footwear with good traction as the wooden platform and surrounding paths can be slippery from constant mist.
Bring a rain jacket or a waterproof cover for your camera, as the viewing platform is often shrouded in heavy spray.
Combine this visit with the nearby Wachirathan Waterfall to see two major park features in one trip.
Attempting to swim or climb the rocks near the waterfall, as the current is extremely dangerous and strictly prohibited.
Maintain a quiet volume to respect the protected park environment; do not climb over safety railings at the viewing platform.
