Just getting to this scenic 1890 lighthouse, overshadowed by Diablo Canyon nuclear power plant, is an adventure. The cheapest way to reach the lighthouse is via a rocky, crumbling, 3.75-mile round-trip hiking trail, for which guided hike reservations are required. If you’d rather take it easy and ride out to the lighthouse, join an afternoon trolley tour, for which reservations are also required. Inside the lighthouse you can inspect an original Fresnel lens and authentic Victorian period furnishings.
The Pecho Coast Trail to the lighthouse is open only for guided hikes led by Pacific Gas & Electric (PG&E) docents, weather permitting. These guided hikes are free; children under nine years old are not allowed. Call for reservations at least two weeks in advance and bring plenty of water.
