Hiking Lower Tuscohatchie Lake via Denny Creek Trail

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.

WTA Pro Tip: Save a copy of our directions before you leave! App-based driving directions aren't always accurate and data connections may be unreliable as you drive to the trailhead.

Getting There

From Seattle, head east on I-90 to exit 47 Denny Creek/Tinkham Road. At the top of the exit ramp, turn left and cross over the freeway. Go 0.2 miles and turn right at the stop sign onto Forest Road 58. The road crosses under the freeway, after driving 0.2 miles, turn left.

Continue straight on for 2.9 miles and about a half mile past the Denny Creek Campground there is a large paved parking lot on the right that can accommodate about 60 cars.

The trailhead can be accessed via a trail that begins near the bulletin board in the parking lot.

The Denny Creek parking restrooms are closed, but the restrooms at Franklin Falls are available to hikers.

There is ADA parking available nearer the Franklin Falls trailhead. Be sure to have a placard; parking patrols are on and will ticket violaters.
