Hiked this in October. Gorgeous views and we were the only people in the drainage. While we didn't find a trail due to snow, the orienteering was incredible easy and the Brookies were biting flies. We exited via the hypotenuse.

Hiked this at the end of a multi-day trip with a base camp on Big Sandy Lake. Maps didn't show a trail but because of such high use found a trail about 2/3 of the way to the lake coming up the ridge near the river drainage from the lake. Small beautiful lake that is less heavily used than Big Sandy
