Mt. Tallac Trailhead
When driving to the trailhead, make a turn inland at Mt. Tallac Road and follow the well-signed route to the reasonably sized parking lot.
Be sure to register your day hike in the Desolation Wilderness area. Free permits are available at the trail sign, which must be filled out in full before proceeding on the trail.
The route begins through light forest before heading up to a ridgeline which follows alongside the shores of Fallen Leaf Lake and provides some great views.
