blue, green, red bar
Snow Valley and Snow Summit Bike Parks are Southern California's best lift-served downhill trails and cross-country riding. Both locations offer a range of downhill mountain biking trails with Snow Summit's backside supporting over 60+ miles of cross-country trails. Please note: Cross-country trails are not owned or operated by Big Bear Mountain Resort.

The Bike Parks operate during the summer months when the snow has melted, making it a popular destination for mountain biking enthusiasts. Here are some key features and details about the Bike Parks:

Trail Variety: A diverse selection of trails catering to riders of various skill levels, from beginners to advanced riders. These trails can include downhill-focused routes, flow trails with berms and jumps, technical trails with challenging features, and cross-country trails for those who prefer longer rides and varied terrain.
Terrain and Features: The trails are designed to incorporate a mix of natural and man-made features to provide an exciting and challenging riding experience. This can include jumps, drops, rock gardens, wooden features, and more.
Scenic Views: Situated in the San Bernardino Mountains, riders can often enjoy beautiful scenic views while descending or riding through the trails.
Seasonal Operation: Both Bike Parks operate during the summer months (typically May/June through October), opening after the snow has melted and the ski season has ended. It's important to check the hours of operations page for the most up-to-date information about operating hours, trail conditions, and any changes in schedule.

      The U.S. Forest Service manages most of the trails in the San Bernardino National Forest, but its budget doesn’t account for all of the trail work needed annually. Without regular maintenance, trails may fall into disrepair and become unusable, and potentially harmful, to the natural environment. To assist the Forest Service's trail maintenance efforts, the San Bernardino National Forest, City of Big Bear Lake, San Bernardino County, Big Bear Mountain Resort, Southern California Mountains Foundation, and Big Bear Valley Trails Foundation have united to form the Trails Advisory Group, which is dedicated to improving non-motorized trails across Big Bear.

      NOTE: Ebikes are bicycles equipped with a battery-powered “assist” that can be engaged while pedaling. When pedalling an ebike, the electric battery kicks in and provides additional pedaling power. Ebikes are a great option for beginners, riders with physical limitations, or anyone looking for a boost while riding from uphill ascents to all-day expeditions.
