Do you love riding bikes? So do we! We all have a story of showing up at the trailhead, setting out for the day, and riding the whole trail network uphill, or worse, spending a whole day planning a ride. We are here to take the guess work out of your mountain bike adventure and to show you some of our favorite rides. Choose from an iconic trail, a mellow day of discovery, or a tried and true singletrack loop. Interested in riding the famous Colorado Trail? We do that, too!
Our guides are experienced in mountain bike instruction and make it their goal to choose the correct terrain for your ability, fitness level, and overall desires. Just bought a bike, took a recent skills course, and are looking for a next level experience? Let us create a ride just for you. Half and full Day options, as well as instructional skills-focus available. Need a bike? Let us know, and we’ll help with your rental or demo!
We will meet at the CAG office or a convenient rendezvous point, gear up, and head to the field. We will spend the day in field instruction where we turn the backcountry into an experiential classroom where you will learn and hone your mountain bike riding skills.
Colorado Adventure Guides is permitted to operate in a variety of terrain in Summit and several adjacent counties, which allows us to access a variety of zones for courses. Typically we confirm our destinations about two weeks before the actual course to make sure we have the most appropriate terrain for the course. Some of our favorite mountain biking areas include:
Experience flowy downhills, grinding climbs, and historic mining roads. Tucked in the foothills of the Rocky Mountain’s Tenmile Range is Breckenridge, a small town with big mountain biking trails and terrain. At an elevation of 9,600′ with 800 miles of track — it is also a Gold Level Bicycle Friendly Community, awarded by the League of American Bicyclists. Mountain biking and cycling are a huge part of Breck’s backbone. From adrenaline downhills to relaxing cruisy trails, the town’s incredible network of trails all boast easy access and will take you up and down Colorado’s famed terrain. Get ready for alpine singletrack, loamy forest trails, and fields of wildflowers as far as the eye can see.
Mountain biking in Summit County is more than flumes, pine forests and mine tailings. When you get away from the Breckenridge area — home to the county’s most popular trails — things open up to reveal rolling meadows and faded ranch buildings. It’s the other side of life in the Rocky Mountains: Alpine ranching, the High Country’s last, great industry before the rise of ski tourism. On the west side of Keystone Resort is a system of trails that weaves past the fairways of Keystone golf club and then north into Frey Gulch or south into Horseshoe Gulch/Soda Creek. The systems eventually connect with the wooded routes many mountain bikers know and love — Blair Witch, Gold Run Road, the Colorado Trail — but for a few short-and-sweet miles, it’s a taste of riding not often found in these parts (unless you want to pedal high above tree line, that is.)
Frisco is surrounded on three sides by national forest (75% of Summit County is public land.) It takes locals years to bike it all, so you will never be bored! The good news is that you can learn to mountain bike or fulfill all your dreams of gnarly mountain biking achievement all right here. We’ve got it all. One of the county’s most popular, early-season mountain bike trail networks is the Frisco Peninsula. For many Summit County residents, the peninsula trail system is the first place to go when the snow melts in the spring. Typically the first to thaw out, it’s a great place to warm up for the season, get used to the altitude, or just enjoy a beautiful trail ride next to Lake Dillon at any time during the summer. The network includes short interconnected trails, so get out there and explore. This is a classic lunch hour ride with incredible views and waterside riding along Dillon Reservoir. There are a lot of trails in this system, and they are perfect for exploring with little chance of getting lost on this peninsula.
Right out of the back door of our office in Silverthorne lies the Salt Lick Trails System. This series of trails pass through stands of lodgepole pine and aspen where you are greeted with amazing views of Lake Dillon, the Continental Divide, and surrounding areas. The Salt Lick Trail System offers intermediate routes for more novice mountain bikers, and includes Ute trail names such as “Nah-oon-kara,” the Ute name for the land where blue water meets the sky, “Too-pwech” which means rock, and “So-ov” which means aspen tree. You can take the Summit Stage to the top of Salt Lick and ride the trails down, or pedal from the bottom up to different types of loops and plenty of rolling terrain.
Colorado Adventure Guides and Colorado Rafting Company, based in Silverthorne, CO, deliver four-seasons of outdoor adventure and education. With operations in seven USFS and BLM ranger districts, we serve a dynamic and growing population of outdoor enthusiasts spanning Summit and Eagle Counties to the Denver Front Range. Our all-season, guided operations include:
We have been providing incredible experiences to visitors of Summit County and surrounding areas for over 20 years. Whether you’re a first-timer or a seasoned expert, let us take you on your next unforgettable outdoor adventure!
Colorado Adventure Guides’ priority is keeping our patrons and students safe. Our instructors are trained to recognize potentially hazardous situations in the backcountry. This can be a physically demanding activity, and your ability to enjoy the adventure depends on your health and fitness, thus it’s recommended that you are in good physical condition.
All of our mountain biking trips will be operated on dirt trails with varying length and difficulty. We strongly encourage that all participants are on full suspension or hard-tail style mountain bikes with disc brakes and flat footed pedals.
We partner with local mountain bike rental shops, and the rental cost is $80 per bike. We take the stress away and get the reservation all set up for you. Mountain bike rentals are typically full suspension bikes with flat pedals and disc brakes, and are sized to the individual.
The best time to go mountain biking in Colorado is whenever you can get out! Our biking season can vary yearly and by location, but here in the high elevations of Summit County, our biking season typically begins mid to late May and lasts through September and some years into October.
Your guide/instructors work hard before, during, and after your course to provide you with a great experience, and while not expected, gratuities are always highly appreciated. If you had a safe, educational, and fun experience, gratuities typically range from 15-20%.
Staying hydrated is essential, especially on long rides through Colorado’s mountain climate.
Mountain weather can change rapidly, so dress in breathable layers to adjust throughout the day.
Make sure your rental bike is properly adjusted before setting off to avoid discomfort or injury.
Silverthorne sits at high elevation, so pace yourself and allow time for acclimatization.
Many trails follow historic mining roads from Colorado’s gold rush era in the late 1800s.
