Sam Lan Waterfall is uniquely characterized by its wide rock terraces stacked in three distinct levels resembling a staircase, which inspired its name Sam Lan, and it is most stunning during the rainy season (July-October) when water flows abundantly over the stone layers. Located just a short 300-meter walk from the park office, the waterfall features an easily accessible trail, making it a popular relaxation spot for families looking to enjoy the water amidst a lush forest setting. As of 2026, the admission fee for Thai nationals is 20 THB for adults and 10 THB for children, with this site serving as a key gateway to other nature study trails like Pho Hin Dat and Ton Rak Sai waterfalls, offering tranquility and privacy for nature enthusiasts.
