Muak Lek Waterfall is a uniquely beautiful small waterfall located within the Muak Lek Arboretum, featuring wide rock rapids where water cascades down in gentle tiers amidst a lush forest environment that provides shade all year round. The water flows from streams within Khao Yai National Park, ensuring it remains clear, clean, and refreshing—perfect for swimming or enjoying a relaxing picnic by the water's edge. A popular must-do activity is admiring the view from the suspension bridge spanning the stream, which offers a picturesque vantage point of the entire area. Its ease of access and natural charm make it a perfect destination for visitors of all ages looking to experience nature's tranquility along the historic railway route.
