The 2,000-acre University of California Santa Cruz campus nestles in the forested hills above town. Its sylvan setting, ocean vistas, and redwood architecture make the university worth a visit, as does its arboretum ($5, open daily from 9 to 5), whose walking path leads through areas dedicated to the plants of California, Australia, New Zealand, and South Africa. Free shuttles help students and visitors get around campus, and you can join a guided tour (online reservation required).
