While the 220-acre Wildwood Retreat Center caters to groups who wish to rent the entire center, it also welcomes individual guests when not otherwise occupied. Located only 10 miles from the Pacific coast and in the heart of Sonoma wine country, Wildwood Retreat Center is the ultimate getaway, although you may never want to leave the grounds! As Wildwood Retreat Center is run by a non-profit conservation foundation, it sometimes offers free room and board in exchange for volunteers who do work around the retreat.
