The Old Tiburon Rail Trail is a scenic 2.6-mile path along the San Francisco Bay, with breathtaking water views and Mt. Tamalpais. Starting at Blackie's Pasture, it winds past coastal mudflats full of wildlife before transitioning into an on-street bike lane leading to downtown Tiburon. It's a fantastic, smooth ride with historical markers, parks, and a ferry terminal at the trail's end, making it an ideal place to enjoy nature and local history for a day away from the big city.

February 5, 2025, Mountain Home Inn

Now open for more than a hundred years, this inn welcomes visitors high on the flanks of Mount Tamalpais. The guestrooms mostly face east, but the grounds include great vantages to the west over the Bay. There's also a restaurant, and this has been voted one of the most romantic spots in the Bay Area several times over.
