The Bizz Johnson is approx. 25 miles long from Susanville to Westwood. Most people who ride the entire distance start at the Westwood end, because the entire distance is downhill back to Susanville. The Lassen Rural Bus out of Susanville runs a shuttle from Susanville to Westwood for you and your bike during the summer months, so you can avoid the transportation delimma. It's currently March 10, and last weekend I was snowshoeing on about 3 feet of snow at the westwood end of the trail, but the Susanville end looked like summer. Check current conditions before heading out. There are 2 other points to pick up the trail if you don't want to ride the whole way: Devil's Corral, approx 5 miles from Susanville, and Goumaz, approx 10 miles from Susanville. Devil's Corral is more popular, because it's right off of the highway, and Goumaz is about 9 miles off of highway 36 on dirt logging roads. The 25 miles is a relatively moderate ride, becuase it's all downhill, and becuase it's a rail-trail: it was built as a railroad line when trains still couldn't climb more than a 1% grade. So today it's basically a well maintained dirt road that's never very steep. For the most part the trial is beautiful, winding along the Susan River, crossing wooden bridges (a few good swimming holes along the way) and traveling through tunnels built in the 1800's for the railroad. Lights are not necessary, the tunnels are fairly short. The Lassen National Forest is beautiful country. The 10 or so miles closest to Susanville are more visually appealing in my book. This is a great family trail..definatetly not anywhere near technical by any definition. It's worth doing, however, for the scenery, and because you probably won't see another soul the entire way. The trail is open to horses and hikers, so be alert. Bike rentals are available at the Susanville end of the trail.
