Campgrounds and RV parks near Clearlake, CA

The lake drives most activity. Clear Lake is widely regarded as one of the top bass fishing lakes in the country, and the area is popular for all kinds of water recreation, including swimming, fishing, boating and water-skiing. Public access points at Redbud Park, Highlands Park, and Austin Park sit within ten minutes of central Clearlake, and Austin Park includes a playground and a swimming beach useful for families. Boat and kayak rentals are available locally. Land-based options include hiking and mountain biking around Boggs Mountain, oak-woodland trails inside Clear Lake State Park, and birdwatching along the Pacific Flyway. The reedy shoreline near Cole Creek includes a no-wake zone that protects a major grebe breeding ground and is well suited to canoeing and kayaking. Anderson Marsh State Historic Park adds wetland walks, and the Napa Valley wine region lies south for day trips.

Clearlake has a Mediterranean climate with hot, dry summers and cool, wet winters. Summers are hot, arid, and mostly clear, while winters are cold, wet, and partly cloudy. Summer is peak season for RV travel: highs commonly reach the upper 80s to mid 90s Fahrenheit, rainfall is near zero, and skies are clear almost every day in July and August. Demand spikes around holidays and weekends, and Clear Lake State Park sites should be booked as far ahead as the system allows. Spring brings the most comfortable temperatures, wildflowers, and good fishing conditions, though March can still be wet. Fall cools quickly after September and offers lower crowds. December is Clearlake's coldest month, with average highs near 53 Fahrenheit and lows near 38, and the area sees roughly 17 inches of precipitation annually concentrated in winter. Wildfire risk runs from late summer into fall across Lake County, and travelers should check CAL FIRE and park advisories before arrival. Accommodations are available year round at Clear Lake State Park, with reservations recommended mid-May through mid-September.

Most private campgrounds around Clearlake are small, older properties with a mix of full hookup pull-throughs and tent sites. Amenities are basic but functional, often including a pool, a boat launch, and rental paddlecraft. Cell coverage is generally reliable in town but can be spotty around the state park. State park sites can fit RVs up to 35 feet and have no electrical or water hookups, so arrive with full freshwater tanks and charged batteries. Generator hours are restricted, typically late morning through early evening. Summer days are hot and dry, so shade and water matter; mosquitoes can be common near the marshes, and poison oak grows along many trails in the Clear Lake area. To prevent the spread of invasive insects, firewood should be obtained locally. Dogs are allowed in campgrounds on leash but not on state park trails.
