Boggs Mountain Demonstration State Forest Weather

Viewpoint • San Francisco Bay Area

Boggs Mountain Demonstration State Forest covers about 3,500 acres of ponderosa pine and mixed conifer forest on Boggs Mountain near Cobb, in southern Lake County. CAL FIRE owns and manages it as a working forest rather than a park. Friends of Boggs Mountain and the Redwood Trails Alliance rebuilt its trail network after the 2015 Valley Fire. Mountain bikers make up about half of its visitors, along with hikers, horse riders and campers at Calso Camp.

What shapes Boggs Mountain Demonstration State Forest's weather

Elevation keeps summer days at Boggs Mountain milder than on the valley floors, but much of the shade that once softened summer afternoons is gone. The Valley Fire killed most of the mature trees in 2015, and the replanted forest is still young. Open stretches of trail take full afternoon sun and dry out quickly after rain.

Fire weather decides access to Boggs Mountain as much as rain or heat does. In September 2020, with firefighters stretched by wildfires across the state, CAL FIRE closed the forest to vehicles to cut ignition risks. People could still walk in from the main parking area by headquarters. Hot, dry, windy days in late summer and fall are the ones most likely to bring restrictions.

Tips for visiting Boggs Mountain Demonstration State Forest

  • Download the current trail map

    Friends of Boggs Mountain posts an updated trail map and notes on rebuilt and new trails.

  • Expect closures in extreme fire weather

    CAL FIRE has closed the forest to vehicle access during statewide fire emergencies, leaving only walk-in access from the main parking area.

  • Keep fires in the camp pits

    Campfires are allowed only in pits or stoves at camping areas and must be attended. Smoking is limited to camps, vehicles, or cleared bare-soil spots.

  • Drive slowly on marked roads only

    Vehicles must stay on marked roads, the speed limit is 15 mph, and drivers yield to hikers, riders, and cyclists.

  • Leave target practice at home

    Target shooting has been prohibited since the 2015 Valley Fire and remains banned until further notice.

Boggs Mountain Demonstration State Forest through the seasons

Spring (March–May)
Spring is prime riding season as the trails firm up after winter, and the forest has hosted mountain bike races in May.
Summer (June–August)
Summer days are warm but milder than in the valleys below, and burned sections have little shade. Ride or hike early.
Fall (September–November)
Fall is fire-weather season until the rains arrive. In September 2020 CAL FIRE closed the forest to vehicles during statewide wildfires.
Winter (December–February)
Winter is cold and wet, with a few freezing nights and snow possible at this elevation. Give the trails time to dry after storms.

Activities and the weather that matters

  • Mountain biking: Best on dry spring and fall days. CAL FIRE's forest manager has said mountain bikers make up half of recreation use here.
  • Hiking: Summer hikes are cooler than in the valleys, but go early because many burned sections are exposed.
  • Horseback riding: Spring and fall are most comfortable. A horse camp has a manure bin, and horses stay out of Calso and Ridge camps.
  • Camping: Camping is best from late spring into fall, in designated campgrounds only. Fire restrictions can apply in hot, dry, windy weather.
