Ride Specifics

Our first trip offering is a sampling of the finest trails the Lost Sierra has to offer. We have named this trip “Day of Descent”, and with over 12,000 vertical feet of descending we think the name fits just right.

The Day of Descent starts with a Mt. Hough descent, followed by The Downieville Downhill, and we top it off with Mills Peak in Graeagle. When all is said and done, you have descended over 12,000 vertical feet, and covered almost 40 miles of trail! Oh yeah, and with minimal uphill pedaling!

Included in this trip is a full day private shuttle for the group, 2 guides (a guide rides with you), drinks, snacks and lunch from a local café. This is the perfect way to ride some of most sought after trails and do it in a convenient fashion.

Think of it more as a party style ride, bring your friends, meet new people and get ready for the good times to begin.

How it Works

Its pretty simple actually, we have taken care of all the hassle for you. We meet in the town of Graeagle around 7:30am and aim to be departing for Mt. Hough at 8:00am. Once we arrive at Mt. Hough we descend into Quincy.

Once in Quincy, our van is there ready and waiting for us, we then load up and have a hour drive to the top of Packer Saddle. At the top of Packer Saddle, we descend into the town of Downieville via the classic Downieville Downhill, where the van is once again waiting for us. This time though, with lunch and cold beverages.

As our food digests and our bodies recover, we drive over Gold Lake Highway and drive to the top of Mills Peak. We finish the day right back where we started and we remanence on the good times we had with cold drinks in hand!

Looking for Something Different?

We offer custom trips by request only, no trip or event is too big or too small. Whether you want to ride one of the classic descents in the area, or set up a multiday event, we have you covered. Check out the Yuba Mountain Guide page for details.


What do I need?
We recommend wearing or bringing anything you would normally have on an all-day ride. Plenty of water, trail food, small personal items, a good working bike and you being in good physical condition. Upon signing up for a trip, you will be sent an itinerary, pack list and medical form. Be sure to check the weather and dress appropriately.

When Should I Arrive?
We recommend arriving about 30 minutes before the start of your trip. This gives us plenty of time to make sure everything you need is sorted for the day.

What if I want to demo a bike?
All demo bike arrangements can be made through Yuba Expeditions. We can help sort out getting the bike to the meeting place for the days ride.

What is the level of skill needed?
The Lost Sierra doesn’t offer many “green” trails, we recommend that you are at least an intermediate rider in good physical condition. The riding in The Lost Sierra has something for everyone, but most of our trails are for the adventurous at heart.

What if I need to cancel?
We will refund 100% within a week, 50% within 3-7 days and no refund within 48 hours. If needed, we can work with you and reschedule for a later date.

What if my bike breaks?
All of our guides were at one point mechanics, they carry pretty much anything needed for trailside repairs. We do recommend you have a small standard repair kit with you (tubes, patches, multi tool etc..) with you.

Who are your guides?
Our guides have been long exploring The Lost Sierra and know these trails like the back of their hands. They are all local, full time employees. Our guides work in the industry year round and have guided all over the world. Each guide not only knows the trails, they are bike mechanics, hold at least a Wilderness First Responder and adhere to industry standards.

Who do I get ahold with any other questions?
Feel free to email Yuba Mountain Guides Operational Director, max@sierratrails.org
