45-minute loop in the redwoods above UC Santa Cruz and along the coast. Take Empire Grade along the west side of campus, turn left in ~9 miles at Pine Flat Road, turn right in 4 miles at Bonny Doon Road, then left when you get to Highway 1, which will take you back to Santa Cruz. It's pretty winding, so not for people who get motion sick easily.
Places to eat, drink, shop, and see shows.
