From Jackson take 191 North to the Scenic bypass road at Moose. Continue to North Jenny Lake Parking lot. Take hiking trail towards Solitude Lake. This is about 0.5 miles before it reaches the trail from the Jenny Lake Ferry.
Highly recommend the full 18 mile round trip hike to Solitude Lake.
A gorgeous day in mid-September. Trees in color, dark green pines, snow-capped mountains, blue sky.
