Easy hike for the first 4.5 miles the the rock field. The rock extend about 3/4 of a mile and it’s slow going. We did not find or use a path through - this made it tougher and it wore me out. Poles make a huge difference. After the rock field side hill next to Symphony pond then work your way up to the Tarn. Out down rout is better than this rout but there may be a better one
