Biking

The Shasta-Trinity National Forest is a bicycling and mountain biking paradise. Many of the forest's best mountain biking routes are on roads and trails that are steep, rough and un-maintained. 

Best Practices:

  • Always wear your helmet and gloves and ride with a buddy.
  • Carry basic tools - wrenches, screwdriver, chain breaker, pump, patch kit and spare tube.
  • Trails at Shasta Lake are open all year, but it is best to hike them in the spring and fall.
  • If you choose to hike these trails in the summer, be sure and take plenty of water. Summer heat is quite severe in this area and there is no drinking water available.
  • Pets are allowed in the recreation areas unless posted. They must be on a leash when in a developed site.

We offer various brochures on biking trail opportunities:

Please note: Bikes are not permitted within any designated wilderness area or on the Pacific Crest Trail.

Mountain Biking

Four areas of particular interest to mountain bikers are:

South Fork National Recreation Trail

This 21 mile long trail begins at Hell Gate Campground near Forest Glen and ends at Double Cabins on Forest Road 28N23 in the south. It is open to hikers, equestrians and along some stretches to mountain bikes. It follows the South Fork of the Trinity River closely so there is water along most of the route.

**Please note: The footbridge that crosses the South Fork Trinity River Trail accessed from Scott Flat Campground is damaged and closed at this time. The good news is there is an alternate route! 

How to get there: If going west on Highway 36, Forest Glen campground will be on the right (north side) of the highway. You will pass over the South Fork Trinity bridge and immediately after on the left is the 1S26 Road. Drive 1.5 miles up the 1S26 Road (it is passable in a passenger car, but there could be rocks in the road that you will need to get out and move) and the trailhead will be on the left. It is marked with a sign leaning against a tree. Turn around and park back down the road a little in the wide areas on the road. Walk back up to the trail head, pass around the gate, and you will be on the trail. The Scott Flat footbridge is about 0.5 miles from this point. The trail continues on for about 18 miles with the other end of the trailhead off of the 29N30 Road at the Double Cabins Site. Please do NOT block access to the gate with your car.
