The Sierra Trek is Cal4Wheel’s premier annual off-road event and one of the most recognized trail runs in the country. Held in the Sierra Nevada mountains near Truckee, California, the event brings together four-wheel-drive enthusiasts for four days of guided trail adventures through alpine forests, granite rock formations, mountain lakes, and historic backcountry terrain.

Participants can choose from a wide range of trails suited for nearly every experience level and vehicle build — from scenic beginner-friendly routes to demanding technical rock crawling. Every trail group is led by experienced volunteers and trail leaders, making the event approachable for newcomers while still offering plenty of challenge for seasoned drivers.

More than just a trail ride, Sierra Trek is a full community experience. Attendees enjoy group camping, nightly gatherings, vendor participation, raffles, and the opportunity to connect with fellow off-road enthusiasts from across the region. Whether you are attending for the scenery, the technical driving, or the camaraderie around camp, Sierra Trek represents the spirit of organized four-wheeling and responsible trail recreation in the Sierra Nevada.
