Within the Wildlife Sanctuary, there are several interesting attractions: - **Ti Lo Su Waterfall**: This magnificent limestone waterfall is situated at an elevation of 900 meters above sea level, where the Glo Toh River cascades over steep cliffs. With a flow that is strong year-round, the waterfall spans approximately 500 meters in width and drops around 300 meters in height. It is surrounded by lush, pristine rainforest. The name "Ti Lo Su" comes from the Karen language, where "Ti" or "Thi" means "water," "Lo" or "Law" means "fall," but "Su" doesn't have a direct translation. Therefore, "Su" is replaced with "Dum," which means "black," giving the waterfall its name, meaning "black waterfall." - **Getting There**: Travel via Highway 1090 (Umphang-Mae Sot) to kilometer marker 161 at Ban Mae Klong Mai, then turn right onto Highway 1288 (Ban Mae Klong Mai-Beng Khleng) until you reach the Dela checkpoint, where you turn left into the Umphang Wildlife Sanctuary. This section of the road requires a high-performance pickup truck or four-wheel drive. The total distance is about 50 kilometers. Note that during the rainy season, this route is closed to vehicle traffic due to difficult navigation and to allow the forest to regenerate. Tourists wishing to visit during this time must obtain permission from the Umphang Wildlife Sanctuary officials. There are two ways to access the waterfall: 1. Rafting down the Mae Klong River from Umphang's sandbank takes about 3 hours, and then it’s a 10-kilometer trek to Ti Lo Su Waterfall, which takes an additional 3 hours on foot. 2.
