Costanoa...

A beautiful eco adventure resort on the California coastline, Costanoa was one of my favorite destinations when I lived in San Francisco. Stay in the lodge, log cabin, tent bungalow, or pitch your own. You don't have to stray far from the grounds, as beautiful hiking and biking trails are as plentiful as the lush mountain views from your cabin porch. You can also horseback ride on the beach across the way or take surf lessons. After the outdoor action, pamper yourself with access to the sauna, yoga classes, hot tub or spa treatments. Cook at the open camp, or sit down for casual organic fare at the bar and grille. A little over an hour south of SF, rates range from $95-$365 per night.
