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.
