Mammoth Mountain’s Bike Park boasts 80 miles of single track. With a vertical rise of more than 3,000 feet, the resort offers 3,500 acres of riding.

More than half of the 42 named trails can be handled by beginner and intermediate riders. Another third are reserved for advanced riders, while 20 percent is recommended for professional riders only. They can all be reached from the Panorama Gondola.

Some of the downhill trails have developed a cult following. Some brave riders take Kamikaze, the first trail dating back to 1987, which sends them barreling down 2,000 feet of fire road from the summit to the Main Lodge.

The Twilight Zone ski trail has carved-out berms and pavers. Then there’s Pipeline, a trail with many man-made features including dirt jumps, wooden ramps, trestles gaps and a great step-up jump.

A little less harrowing is Beach Cruiser, a wonderful 4-mile intermediate track. It climbs through large Lodgepole pines before looping around Reds Lake for a long roller coaster ride back to the Main Lodge.

Then there’s Paper Route/Skid Marks/Manzanita, the intermediate course used for the resort’s 8/24 Endurance Race. This rolling loop offers fast downhills and technical sections, as well as a couple switchbacks at the far end. (This year’s race, originally scheduled for this weekend, was cancelled.)
