Epic views of San Francisco, Point Bonita Lighthouse, the North Coast, and WW2 bunkers and ruins.
All throughout the Marin Headlands are WWII-era bunkers, batteries and ruins, including a complex on the hillside above the Point Bonita Lighthouse that provide amazing views of San Francisco, the Golden Gate, and the north coast.
Drive out to the parking lot for the Point Bonita Lighthouse in the Marin Headlands and take the trail to the lighthouse about 80 feet and then scramble up the hill to the right through the trees before you the trail begins its decent. You'll find yourself on a cliff high above the Pacific. Proceed to your west around towers and bunkers until you reach a flat, exposed area that overlooks the lighthouse and the trail to the lighthouse.
