Situated in the arboretum only one kilometre off of the main highway 12 (Phitsanulok – Lom Sak Road) Kilometre 33, the small fall is surrounded with different kinds of plants. On the west is a royal pavilion that once welcomed Their Majesties the King and Queen during their royal visit to the North, with another pavilion by the water in the east. Nearby is Sai Rapids, where visitors can enjoy the scenery. Within the park is Namtok Wang Nok Aen, a 10-meter high waterfall, that cascades down the rock with strong currents that have gradually shaped the stones into the most unique formations.
