Thanks for visiting the Sonoran Desert Mountain Bicyclists! We are an all-volunteer 501c3 non-profit organization devoted to the promotion of mountain biking, and view the sport as a vehicle to promote low impact outdoor recreation, conservation, and opportunities that are environmentally and socially responsible. We hope that you will use this website as your Tucson mountain biking resource for finding events and trails to ride, as well as to stay up-to-date and help our trail advocacy efforts.

Tool Cache at Starr Pass


Some of us just can’t get enough trail building, so we are going to keep working at Starr Pass over the summer! The plan is to cache tools at the work site so that we can ride in after work, work until dark, and ride out with lights.

This coming Tuesday we are going to hike in our tools, and the more folks we have means the more tools we can carry. Meet at the Sarasota TH at 5:30, and bring a headlamp for the hike out. It will be hot, so bring plenty of water and a frosty adult beverage if that’s your thing. If there’s time, we will do some digging as well.



June Skills Ride at Sweetwater




Join PMBIA-certified MTB Skills Instructor Edy Yee for June’s Skills Ride at Sweetwater on Saturday, June 25 at 6:30 AM! Sweetwater is a perfect trail system for beginner/intermedate riders to work on technical climbing and descending, along with bike-handling skills on loose and rocky terrain.

This skills class is FREE for SDMB members. If you’re not already a member, click on the join SDMB button to join. The class is limited to 10 participants, so sign up soon! Follow the Doodle link above to register.

Riders should be comfortable riding trails like Fantasy Island, Honeybee Canyon, and the Arizona Trail, or have taken Edy’s Level I class to get the most out of this Skills Class. Riders must have a helmet, a well-maintained bike, and water.

Honeybee Canyon/Tortolita Mountain Access Update


As most mountain bikers in Tucson are already aware, there are a number of access issues going on right now at Honeybee Canyon in Oro Valley. Representatives from the MTB community are in touch with the respective stakeholders to try to find solutions. Here is an update of the current situations. Most of this information has already been posted, but we wanted to get everything in one place.

Parking Issues at 1171 E. Rancho Vistoso Blvd (Fast Rhino/Cop Shop):

First off, the property management who runs the commonly used parking area at 1171 E. Rancho Vistoso Blvd (sometimes called the “Cop Shop”) has, for the time being, prohibited non-customers from parking there 7 days a week. This has always been a popular place to park for folks using the Honeybee trails and, and since the Como Rd. access was closed off it has seen a huge spike in use. Numerous road cycling groups also use the lot to start and finish rides, sometimes having as many as 50 plus riders. There have been issues with folks parking there for years, mainly due to some local residents who were hostile to bikes, but things came to a head recently with business owners citing overuse of the lot during business hours, public nudity due to riders changing before and after rides, a recent bike demo day that was not cleared with the owners, and some riders urinating and even defecating at the lot.

Until further notice, please do not park at the parking lot at 1171 E. Rancho Vistoso Blvd. You will likely be towed. It is private property, and the owners are threatening to tow anyone who parks there for cycling purposes. Representatives from the cycling community are in contact with the property management company and are working hard to find solutions to maintain access, and we will update via Facebook and the internet as things progress. Please be respectful of the business owners at the Plaza; getting confrontational will not help us secure access.

April Social Ride – Starr Pass


The newly completed section of trail at Starr Pass is now open! Come join us for our April Social Ride and see what all the buzz is about! It’s warming up folks, make sure to bring plenty of water and electrolytes to get you through the ride. Plan on a 3+ hour ride!

After the ride everyone is invited to 1912 Brewing Company for after ride refreshments. All SDMB members will receive $1 off tap beers. Just another membership perk!

Please be ready to ride at 8:15 so we can organize the groups and roll out.

We are planning on 3-4 levels of rider groups. Pending ride leaders. Let us know if you are willing to help a ride leader.

Easy group will do a clockwise Yetman loop with the new section, at a slower pace and more stops.

Moderate group will do the Yetman loop and add a loop to the Stone House, with less stops and a moderate pace.

Advance group will do both loops and decide if we want to hit the Cat Mountain trail to the top and back down before we do the new section.

Ride Description

Starting at the Genser Trailhead we will head to the 4-way and take the Yetman trail in a clockwise loop to the newly created trail that ends at the Sarasota Trailhead. Then we continue north on our loop to meet up with the Yetman trail again, do the big climb and head down the Yetman reroute back to the 4-way where you can decide if you want more. If not, head back to the parking lot. If you do want more, we will stay on the Yetman trail and head to the Bowen Stone House for a break. After our break, we continue on the Yetman trail until it meets up with the Bowen trail. Take the Bowen trail to the resort and finish off the ride on the road back to the Genser parking lot.

For more and to RSVP, see the Facebook Event.

SDMB Starr Pass Trail Build

Please register via the provided link if you want to come out!  If a work day is full, please check out a different day. Weather permitting, we may schedule additional work days in May.  Stay tuned for details.

SDMB needs your help at the 24 Hours in the Old Pueblo!

Join Sonoran Desert Mountain Bicyclists as we partner with Epic Rides and Sierra Nevada Brewing Company to run the beer garden at the 24HOP for the second year. This year, there will be a second beer garden up at the rock drop in addition to the main beer garden.

As the nonprofit running the beer gardens, all proceeds go directly to support SDMB’s advocacy efforts. We are finalizing a stewardship program with Pima County for county trails including Tucson Mountain Park, Sweetwater, Robles Pass, and Ridgeline Trail. SDMB is raising more than $3,000 to provide stewards with trail tools, training, and incentives to keep the trails we ride and love in great shape.

Shifts are only 1.5 – 3 hours long, so they fit in great between laps during the race. We need 5 volunteers per shift for the main beer garden, and 2 per shift up at the rock drop. Volunteers must be 18 or older. The Main Beer Garden is open from 2 PM – 8 PM on Friday, 11 AM – 9:30 PM on Saturday, and 10 AM – 3 PM on Sunday; the Rock Drop Beer Garden is open from 4:30 PM – 6:30 PM on Friday, 11 AM – 6:30 PM on Saturday, and 10 AM – 1 PM on Sunday.

Please follow the links below to sign up for shifts; there is a separate link for each beer garden. If you have any questions, email trailsteward@sdmb.org.
