Campgrounds and RV parks near Greenville, CA

Lake Almanor is the main draw. The reservoir supports boating, water skiing, sailing, swimming, and fishing for trout, salmon, smallmouth and largemouth bass, and catfish. Forest Service boat launches and several private marinas serve the lake, and swim beaches are scattered along the shore. The paved Lake Almanor Recreation Trail runs along the west shore for roughly 9 to 11 miles one way, with views of the lake, Dyer Mountain, and Lassen Peak, and is closed to motorized vehicles. Lassen Volcanic National Park is reached via the southwest entrance near Chester, putting hydrothermal features, alpine lakes, and the Lassen Peak trail within a day trip. Closer to town, the Feather River and Round Valley Reservoir offer fishing and paddling.

The Greenville area has a four-season mountain climate. Summers, roughly mid-June through August, are warm, dry, and clear, with daytime highs often in the 80s Fahrenheit and cool nights. This is peak RV season: most Lake Almanor and Lassen National Forest campgrounds operate from late spring through early fall, with prime weekends booking out well in advance. Spring brings melting snow, high creek flows, muddy forest roads, and wildflowers at lower elevations. Higher campgrounds remain closed until snow clears, and the main road through Lassen Volcanic National Park typically opens in late spring or early summer depending on snowpack. Fall is shorter and cooler, with crisp nights, light crowds, and some color in aspen stands before the first storms arrive in October or November. Winter is cold and wet, with significant snowfall, chain controls on mountain highways, and most public campgrounds closed. Wildfire risk peaks in late summer and early fall, so travelers should check Lassen National Forest and Cal Fire alerts before and during a trip.

Expect a mountain setting with mixed conifer forest, granite outcrops, and meadows, at elevations between roughly 3,600 and 5,000 feet around Greenville and Lake Almanor. Cell service is patchy outside the towns of Greenville and Chester, and grocery, fuel, and propane options are limited, so RV travelers should top off in Chester or Quincy. Most Forest Service campgrounds offer vault toilets, picnic tables, fire rings, and potable water but no hookups, while dump stations are available at some lakeside sites and at private parks. Black bears are present, so food must be stored in hard-sided vehicles or bear boxes. Mosquitoes can be active near the lake and creeks in early summer. Nights are cool even in July, so pack layers.
