John Bull Trail (3N10)
3N10 east end, approximate mapped road reference, Big Bear / Holcomb Valley area, CA
About this trail
John Bull follows Forest Road 3N10 through the Holcomb Valley area north of Big Bear Lake. Its technical sections have large boulders, steep climbs and demanding rock obstacles, while some eastern approach sections are easier. Use an equipped high-clearance four-wheel-drive vehicle and travel within your experience. The Forest Service Motor Vehicle Use Map designates 3N10 for highway-legal vehicles. Stay on the numbered route and use designated approaches instead of unauthorized obstacle bypasses. Check current forest orders, weather and gates before travel. The pin is an approximate eastern mapped route reference, not parking or the exact technical gatekeeper. The original gallery map shows a historical loop and does not grant access to every connecting road.
