Yuba Expeditions Day of Descent

You fill the van with riders and you choose where to go!
Ride the best shuttle-fed descending in Downieville, Lakes Basin, Mills Peak, and Mount Hough that standard shuttles don't reach.

Have a group of up to nine? Looking to get in a full day of singletrack? Want to ride Downieville and Mills Peak or some other cool combo of rides all in one day? Let’s Go! Our Day of Decent Private Session offerings provide just that. Pick where you would like to start and finish your day, Quincy, Graeagle or Downieville and the van will be there to load everyone up and head out for a day full of descending. Your nine (9) person group has full access to the van from 9am to 5pm for $1,400 for the entire day wherever you go. You can choose from a variety of itinerary options listed below sorted by start finish location. The most recommended ride plan is listed under Signature Selection. These Private Sessions will be available monthly starting in May through October.

Could be up 10,000 vertical feet and 30+ miles of shuttle-fed descending, or it could be a more mellow paced tour of the best descents in the region. You decide!

Signature Rides

Mt. Hough Explorer in Quincy

Beginner to Advanced Riders

Mt. Hough mountain biking

Starting from an elevation of 7200ft. at the Mt. Hough fire lookout with stunning views of Mt. Lassen, Lake Almanor, Sierra Buttes, the fast flowing trails descend 4000 ft. down to the pastoral American Valley. With trail difficulties from easy “green” to very difficult “black diamond” and everything in between, its close proximity to Quincy and easy highway access options form Chico, Truckee and Reno the Mt. Hough network is a great starting point for any two wheeled activity for the whole family and any ability level. More trails are getting dug every year, so new trails are easy to come by. Gravel riding is also top notch in the Quincy area, with hundreds of forest roads, gravel route options are numerous.

This regional ride has great options for families, entry level riders (advanced too!), with the flow trails, and good for gravel riders, moto, cross country and Ebikes.

Route Options

  • Mt. Hough trail to Green Bridge - 12 miles, 4000 ft. descent
  • Mt. Hough trail w/ Chandler add-on - 19.5 miles, 4600 ft. descent
  • Indian Falls Ridge (from Crystal lake to Quarry rd.) 10.5 miles, 4200ft. descent
  • Fireline to Berry Creek - 3.5 miles, 1000 ft. descent
  • Tollgate trail - 2 miles, 1000 ft. descent
  • Grinduro Course

Graeagle / Mills Peak / Lakes Basin

Intermediate to Advanced Riders

Mills Peak mountain biking

The Mills Peak trail is the anchor in this area, but there are so many trails in the Lakes Basin Recreation Area that this trail network can hold its own against some of the most popular areas around. Built as a “wheel optimized” trail, and descending 3000 feet in 10.6 miles the Mills Peak trail has been an instant classic since its completion by the Sierra Buttes Trail Stewardship in 2014. The trail finishes just outside Graeagle, making it very convenient to get to your post ride activities, or to the other trail networks in the area Quincy and Downieville. With its rocky terrain and historic trail alignments the trails around Graeagle are quite technical and recommended for experienced intermediate and advanced riders.

Looking for technical rock gardens? Multiple summit options? Countless lakes? And did we mention the challenging rocks? This is it! No Ebikes and motos on this one, sorry.

Route Options

  • Mills Peak trail - 10.6 miles, 3000 ft. descent
  • Round Lake to Graeagle - 14 miles, 4200 ft. descent 2000 ft. accent
  • Lakes Basin trails

Signature selection

  • Mills Peak, Mt. Hough, Mills Peak
  • Mills, Packer to Downieville, Mills, Brewing Lair
