From Seattle drive east on I-90 to Exit 47. Turn on Denny Creek road and follow for 3 miles to just past the Denny Creek Campground. Turn left, and drive 0.2 miles to the road-end trailhead and parking.

Surprisingly, the bugs weren't a big problem at the lake
On the way back out, the slabs were EXTREMELY crowded
Didn't take nearly enough pictures, unfortunately!
