The Thi Lo Su Waterfall was probably Thailand's biggest waterfall in terms of the cumulative amount of space containing falling water. I've also seen claims that it was the tallest waterfall in Thailand though we weren't sure if that was accurate. In any case, the signs here said there were three distinctive waterfalls comprising the overall waterfall ensemble dropping a total of some 200m, 300m, and 400m, respectively. Again, we couldn't vouch for the lofty 300m and 400m height estimates though.
Julie and I thought the best of the three waterfall segments was the series of distinctive plunging leaps to the left as we were facing the falls. The lowest leaps of the leftmost watercourse had pools where we saw many people swimming, bathing, or just cooling off in general. The middle drops of that leftmost course had much taller and thinner appearances, which might have also acted as barriers for most people in terms of trying to climb up or alongside the vegetated cliff face responsible for these waterfalls.
Many holiday-makers enjoying one of Thi Lo Su Waterfall's many swimming holes As for the other two waterfall segments falling in parallel more or less, the middle segment consisted of thinner yet taller drops. These weren't conducive to swimming like the leftmost series of drops. Similarly, the rightmost drop was perhaps the most ephemeral (i.e. temporary) as it fell far off to the right of the middle segment. Given how spread apart these waterfalls were from each other, there was no way I was able to reasonably compose a singular photo that encompassed all of them from any of the sanctioned lookouts.
Speaking of which, photographing the Thi Lo Su Waterfall was indeed difficult for us. That was because we were constantly tempted to try to capture it all in one shot, but it was simply too wide to fit it all in. All of our attempts at doing this resulted in awkward and unbalanced photos that ended up being candidates for the recycle bin or at least to be overlooked and ignored.
