About This Trail

Imported description
The trail is good for running, but can be crowded. The Lower San Merrill trail leads to Lake. Take the second trail further back towards the mountain. At the top, turn right. The sign for Sierra Saddle should be on the right if you turn left once you hit the paved road.
