A nice trek along the Ridge and then down to the coast and looping back up to the Ridge. Awesome views.
Up Sweeney Ridge Tr, R on Mori Ridge Tr, carefully cross Hwy 1, Upper Mori Tr, L on Lishumsha Tr, L on Coastal Tr, L on Bluff Trail, carefully find a way over to Rockaway Beach and cross Hwy 1 at Shell Station. Go L or north along Hwy 1 and locate the trail behind a church parking lot on right. Ascend eastward and pick up unmarked trail to Baquiano Tr, L on Sweeney Ridge Tr. Here lies a couple of markers indicating where the Portola Exhibition discovered San Francisco Bay in 1769. Continue north on Sweeney Ridge Trail which leads to a series of abandoned buildings that were formerly the site of the SF-51C Nike missile control facility. Continue north on trail back to parking.
Hike at your own risk. We picked a very nice day. Check the forecast as Pacifica can be foggy and cold relative to the Bay Area.
