Most visitors to Santa Cruz know of and visit the Lighthouse at Steamers Lane on West Cliff Drive, the pretty brick one you can see from the Boardwalk and main beach. Much less well known is Walton Lighthouse. This is located at the opening to the working harbor. It is worth going here not just to see the lighthouse, but to enjoy various activities in the area. The harbor itself is beautiful, where dozens of pleasure craft and some working fishing boats berth. On either side of the harbor there are popular local beaches: Seabright to the west and Twin Lakes to the east. And for something to eat, there is Aldo's for informal food and The Crows Nest for a somewhat classier atmosphere. Both have great views.
For many years this lighthouse was not very pretty - just a metal structure topped with the beacon light. A few years ago it was rebuilt in its present form, thanks to donations and efforts from volunteers to get the project going. Unlike the Lighthouse at Steamers Lane, you can't go in this one. It is just for the scenic experience. No museum here.
