Pantoll Road is a beautiful, mostly paved route through Mount Tamalpais State Park, connecting the Panoramic Highway to Ridgecrest Boulevard. It winds closely along the curves of the hillside, with some shade from the trees in some spots. There are fantastic views along the way of San Francisco and the Marin Headlands, with incredible viewpoints over the Pacific coastline.

Nice water resupply spot in the shade and a great picnic area. Good launching point to many adventures around the lakes.

Mount Tamalpais ist with its three summits the highest point of Marin County, California. The Middle Peak is probably the less popular of all three as the West and the East Peak is higher and in addition to that the East Peak offers better views of the San Francisco Skyline. If you don't fancy touristy hotspots, then pick this summit.

This is an easy gravel road along the shore of Lake Lagunitas. If you run out of water just follow the trail around the lake until you hit the parking lot where you can refill your water bottle.
