Location & Getting There

Things to Do
California state parks span an extraordinary range of landscapes — from ancient redwood forests and rugged Pacific coastline to Mojave Desert dunes and Sierra Nevada alpine meadows. Depending on the park, visitors can enjoy hiking through old-growth groves, swimming and surfing along miles of wild beaches, camping beneath towering sequoias, kayaking coastal sea caves, mountain biking oak-studded foothills, fishing in alpine lakes, rock climbing granite formations, and wildlife watching for everything from elephant seals to California condors. Many parks also preserve important cultural and historic sites, including Native American heritage areas, Gold Rush-era settlements, and Spanish mission ruins.
Best Time to Visit
California’s parks are a year-round destination, though the ideal season depends on the region. Coastal parks enjoy mild weather from spring through fall, with summer fog keeping temperatures comfortable along the central and northern coast. Desert parks like Anza-Borrego are best visited October through April — summer temperatures can exceed 110°F. Mountain parks in the Sierra Nevada are most accessible June through October, when snow melts and trails open. Spring (March–May) brings wildflower super blooms in the southern deserts. Fall offers warm days, thinner crowds statewide, and stunning foliage at higher elevations. Winter is the quiet season at most parks and brings excellent whale watching along the coast.
Visitor Tips
Most California state parks charge a day-use parking fee of $10 per vehicle: purchasing an annual pass ($125) is highly recommended if you plan to visit multiple parks. Camping reservations can be made through ReserveCalifornia up to 6 months in advance — popular coastal campgrounds book within minutes of opening. Cell service is limited or nonexistent in many parks, so download maps and directions before you leave. Bring layers: California’s microclimates can shift dramatically even within a single park. Dogs are generally allowed in campgrounds and on paved roads but not on most trails or beaches in state parks.
