Mount Tamalpais State Park is a majestic area in the heart of Marin County, with sweeping hillsides covered in fantastic redwood forest, open grasslands, sturdy chaparral, and wooded oaklands. The views from Mount Tampais boast breathtaking vistas of the Pacific Ocean, San Francisco Bay and City, the Marin County Hills, Mount Diablo, and the East Bay. You can even see the Farallon Islands, 25 miles out to sea. If you're lucky, you can catch an occasional glimpse of the snow-capped Sierra Nevada Mountain Range, nearly 150 miles away. The Park is a haven for cyclists, hikers, wildlife watchers, or those who wish to find a beautiful spot for an afternoon picnic.

Quieter albeit slightly higher and steeper climb out of Mill Valley to Panoramic Highway instead of climbing on Hwy 1, meandering along lesser traffic neighborhood streets with more shade and awesome bay views.
