Namtok Lam Ru, nestled within the expansive boundaries of Khao Lak-Lam Ru National Park in Phang Nga Province, serves as one of the most critical headwater sources for the Lam Ru Yai and Kapong canals. This medium-sized waterfall is hidden within a remarkably preserved tropical rainforest, cascading down a series of five distinct granite levels. Each tier offers unique characteristics, from steep drops to wide, shallow basins. The water flows through massive boulders and lush tropical vegetation throughout the year, ensuring a consistently refreshing atmosphere and pristine air quality for all visitors.

Ecologically, the area surrounding the falls is a sanctuary for rare flora and diverse wildlife. It is a particularly popular spot for birdwatchers and butterfly enthusiasts, as many species frequent the moist stream banks. The trail leading from the parking area to the various levels of the waterfall is designed as a nature study path. Along this route, visitors can observe the complex ecosystem of a tropical rainforest, featuring dominant tree species such as Hopea odorata (Ta-khian) and various Dipterocarpus, alongside intricate ferns and mosses that cling to the moist rocks and ancient trunks.

Managed by the Department of National Parks, Wildlife and Plant Conservation, the site maintains strict safety protocols, with rangers stationed to monitor water levels, especially during the monsoon season when flash floods are a potential risk. Near the waterfall, the park office provides well-organized camping grounds for those wishing to experience an overnight stay in the wild. Sleeping to the rhythmic sounds of the cascading water and the nocturnal forest choir offers a unique natural charm that provides a stark and peaceful contrast to the bustling beach resorts of the nearby coastline.
