Pacifica Vista on Old San Pedro Mountain Road

Highlight • Viewpoint

From this spot on Old San Pedro Mountain Road, you get truly stunning, panoramic views of the Pacific Ocean and surrounding foothills and grasslands. This is a great spot to take in the view and catch your breath before continuing on your ride.

Old San Pedro Mountain Road summit

Highlight • Summit

This isn't the sort of road you'd take a vehicle on, nowadays - but it's great for nontechnical mountain biking, and this high point gives you nice views over the surrounding hills.

Egg Rock — Devil's Slide

Highlight • Natural Monument

Egg Rock is an example of a successful environmental restoration: Once home to a bird colony of thousands of Common Murres, the colony was wiped out by a 1986 catastrophic oil spill. Restoration started in 1996, and by 2013 a viable population was reached again. Still, it took more than 6 millions dollars and 27 years, all the while other less visible consequences of the oil spill might be less visible ... You will need to use a strong zoom or the nearby monoculars to see the birds on the island (never mind the ravens often sitting on the cliffs just next to the road).

Devil's Slide Trail

Highlight (Segment) • Cycleway

The steepest section of the former road that used to be destroyed regularly by landslides. Now a great bike trail with coastal views and no cars.

Devil's Slide

Highlight • Cycleway

While the whole section of the bike trail, now closed to car traffic since the 2013 opening of the tunnel, clings precariously to the cliffside, the worst of the actual slide area is apparent also by the 9% steep section of the trail.
