Built in 1872, still active though in need of repair and closed to the Public, Pigeon Point Light House--Historic State Park---Hostel.
This lighthouse is 50 miles south of San Francisco, between Half Moom Bay and Santa Cruz on The Beach Road. A rugid 115 feet tall lighthouse. Rooms-hostels- $20.00 a night. This was one of the tallest lighthouses in America, a good place for whale watching, hiking and relaxing. Care to help the preservation effort...there's a campaign to Save the Light.
As you drive up the coast, don't pass up opportunities for a bathroom stop, they are few and far between. Take food and water with you, so you can stop along the way and picnic. There are many turn outs that make that possible. Don't count on finding a fast food place to zip in and zip out.
Leave your sandals at home! Or at least in the car and wear tennis shoes and socks, makes for moving around easier.
