The Klo Tho Brook, which originates in the west woodland close to the Thai-Myanmar border, runs into Thi Lo Su Waterfall. The entire river plunges down the steep rock into a thick, expansive tropical evergreen forest. The waterfall is regarded as a distinctively beautiful cascade, and from June 1 to November 31 each year, more precipitation fills the stream, making the fall’s path fuller than at other times. However, it is also the time when the road is shut down to protect the passengers from danger and accidents, as well as to keep the road in good condition.

The background of Thi Lo Su

In the lush jungle, the waterfall known as Thi Lo Su is concealed behind a folded cliff. After Karen Huntsman found it, the border patrol authorities conducted a search of the area and found the waterfall. Later, the area was designated as the Umphang Wildlife Sanctuary by the Royal Forestry Department. After that, a party from a travel magazine conducted a trip to the region in 1985 to investigate everything, including the waterfall. The location’s narrative was then included in the magazine. And so, marks the start of the well-known Thi Lo Su to outsiders.

The region is separated into three sections, the tallest and most important portion of the fall being on the left. There are several streams that cross the cliff’s foot. After that, the middle group is where the water flows from the cliff, which is the same height as the first group, but the stream is not level and is smaller. Additionally, there is lots of water in the right half, and the cliff there is lower than it was before.

The combination of all three components creates a stunning and interesting waterfall that anybody should make an effort to visit. There is also a lookout located on the top of the cliff opposite the fall. It is an excellent place for seeing the waterfall in all its glory. Round way travel time from the waterfall to the viewpoint is 2 hours.
