Lower Tuscohatchie Lake is accessible from multiple different trailheads, offering hikers multiple hiking options. One option is to start from the Granite Mountain/Pratt Lake trailhead.
Start by walking along the Denny Creek trail until you go under the I-90 overpass, where you'll soon begin to climb.
Once you reach the popular spot known as the Denny Creek Water Slide, Slide Rock or Slipper Slab, you'll start your ascent. Parts of the trail up to Melakwa Lake are quite steep and rocky. On the way, you can occasionally get views of Snowshoe Falls and Keekwulee Falls.
Parts of the trail can be quite exposed to the sun or the elements so come prepared. Eventually, you'll go around a mountain where you will lose the sounds of the highway and any cell service. You'll soon arrive at Melakwa Lake. From there, head down a steep trail that eventually evens out, and you'll arrive at Lower Tuscohatchie Lake.
Lower Tuscohatchie has quite a few established campsites with a few of them being shorefront.
There are plenty of water crossings and there is water at the lakes. Having extra water in this area won't be needed as long as you have a filter. In late summer, as creeks and rivers can dry up, having an extra liter of water is advised.
