Great viewpoint along Stagecoach Fire Road. There are picnic tables, so this is a great place for a break to enjoy the wonderful views of Mount Tamalpais.

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.

There is a great view of the northern point of Alpine lake where a small channel feeds over to Bon Tempe Lake. This is a great place to drop a line, or just enjoy the aquatic views.
