Spicer Sno-Park is located just off of Highway 4 in Stanislaus National Forest and offers access some some fun snowmobile trails that lead to scenic mountain lakes. The route to Union Reservoir follows Spicer Meadow Road from the parking area for almost 8 miles to a three-way junction. From here riders will head north for another mile to Union Reservoir. The ride follows gentle terrain with only gradual declines and inclines, all along groomed trails, but visitors should still check on current snow and trail conditions before setting out on machines. A daily fee is required for parking at Spicer Sno-park.
