Perfect for adventure-seeking travelers, reaching the waterfall requires a bit of travel time and some tricky climbing in the afternoon. However, the beauty and majesty of this place have earned Ti Lo Su Waterfall a reputation as one of the must-visit spots, ranking second among the top ten waterfalls in Asia. To visit the Umphang Wildlife Sanctuary or Ti Lo Su Waterfall, all tourists must obtain permission in advance by acquiring a SP7 stamp from the Department of Forestry. This form can be requested through the Umphang Tourism and Conservation Promotion Club. Each year, the Umphang Wildlife Sanctuary closes the access road to Ti Lo Su Waterfall for three months, from June 1 to September 30, due to the rainy season. As a result, traveling to and from Ti Lo Su during this period can be quite challenging.
