We hiked the 11 mile Tripyramid loop which starts out and finishes easy on the Livermore trail. The North Slide is up a steep avalanche scar and ascends 1200 ft in a half mile. The trail then goes up and over Middle Tripyramid to the South Tripyramid slide which descends on loose gravel and rocks. We finished in a little over 6 hours and had a great day. Waterville Valley is a beautiful area with lots of trails to explore!
