Visitors to Sonoma may have a difficult time believing how close they are to the Pacific Ocean – in fact, the rugged Northern California coastline is less than 20 miles from downtown Guerneville. One of the county's premier parks, Stillwater Cove allows visitors to take full advantage of the dramatic Sonoma shore with easy beach access, hand-launch boat facilities, and the appealing prospect of tide-pooling, fishing, and diving in good waters. Restrooms and designated campsites are available.
