To drive this trail, start in Lake City, and travel south on highway 149, following the signs to County Road 30, Cinnamon Pass and Lake San Cristobal. This trail starts past the lake on the other side. All primitive dirt roads may be rocky with areas or soft gravel or sand that makes travel unsafe for sedans or RVs. Some road sections may require a high clearance 4WD vehicle, in four-wheel-drive, driven by a driver experienced in 4WD drive techniques to drive the road without getting stuck.
In summers, this popular trail can be very busy. The road bad conditions, with extremely large pot holes could potentially pop a tire, crack a rim, or screw up your cars allignment. The unpaved sections of the road can be impassable when wet. In any case, driving 4WD is recommended due to uneven surface. During and after a storm the road may be impassable, even with a four-wheel-drive vehicle and can easily get muddy if it rains making it challenging to get through.
