Toxic Forest-Flume Trail

The Toxic Forest area features miles of interconnected trails on private land open to the public, a perfect for downhill enthusiasts and riders looking for a challenge. This area was affected by historical mining activities at the Jumbo Mine, which leached tailings into the surrounding hillside and killed the forest around the mine. With little vegetation, views from the Toxic Forest area are grand, with up to ten-mile views of the surrounding mountains.

The Toxic Forest & Flume Trails are multi-use so riders may encounter hikers, trail runners, 4x4s and other users and should follow right of way protocol when meeting other groups. The Toxic Forest & Flume Trails area located in higher elevation terrain and sudden weather shifts are possible; riders should bring appropriate warm layers in anticipation of this. In addition, riders should be prepared with a stocked repair kit and a first aid kit.

From Breckenridge, take Ridge Street north to Wellington St and turn right. Take Wellington Street to French Gulch Road. Turn left onto Gold Run Gulch Road and climb into the Toxic Forest area. This road becomes the Slalom Singletrack, descends and at a fork, bears right and climbs to the top of the Toxic Forest. This is where a trail map, easily found in Breckenridge, becomes handy for picking and choosing select trail sections within the area.
