June 27, 2025, Four Corners Panoramic Hwy/Muir Woods/Sequoia Valley Rd

This "Four Corners" intersection on the saddle of Panoramic Highway is the transition for Sequoia Valley Rd crossing over to the Pacific side into Muir Woods Rd. There are also three trails arriving from the Bay side at this point. The views reach from the Bay on one side to the Pacific Ocean on the other.

This is a great gravel road that takes you from the summit of Mount Tam to West Point. The road is wide and not very technical, but the views south across the foothills to Muir Woods are fantastic.

November 6, 2023, West Point Inn

Great stop over along the trails on Mount Tam at the intersection of Old Railroad Grade, Old Stage, and Nora trails. Sit and enjoy the views from the wrap-around porch of this former hotel/restaurant built over 100 years ago when 'the crookedest railroad' carried weekend tourists up to the summit of Mount Tam. Today volunteers maintain the idyllic inn, provide hiking information and self-serve honor-based snacks and refreshments.

November 1, 2023, Pantoll Road

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.

Eldrige is a fun, albeit somewhat steep and rocky, gravel doubletrack dropping from the paved road before the summit down the eastern flank of My Tam
