Calvary

Calvary is located near the town of Running Springs at an elevation of 6,500 feet. It is surrounded by national forest and a seasonal stream runs through the site. The trails wind through yellow pine forest, offer views of the surrounding mountains, and include a scenic walk along the stream. Snow is common and lingers most winters.
