Often busy on weekends, this is a great spot to take moment before/after summiting Mt Tam. There are spigots to fill up water and bathrooms that are open during park hours. The parking lot is very close for those that drive up. There is access to MANY trails for those on foot/bike.

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.
