This is an eleven mile loop from the Livermore Trail. We loved the nice easy grade on the Livermore trail to the Tripyramid loop trail. The North Tripyramid slide was 1200 vertical feet in a half mile, very exposed. The rest of the hike was a piece of cake after the N. Slide -- but have to say that going down the loose rock on the S. Tripyramid slide was not exactly a walk in the park. We finished in less than 8 hrs. Saw a hummingbird, a mouse, a really cool frog and maybe a moose crashing through the woods on the way down.
