Bike Park Stats

The Keystone Bike Park consists of some of the country's best downhill trails with progressive terrain for riders of all abilities. Take your bike up a chairlift and gain access to some of Colorado’s most exhilarating expert downhill challenges with rock gardens, rock drops and high-speed features. Beginner and intermediate bikers can enjoy roller coaster rides over bridges and berms without the steepness or rock gardens you’ll find in other areas of the park.
And, Keystone is the hub for hundreds of miles of world-class single track . The Keystone Bike Park trails combined with the trails branching from the Colorado Trail provide seemingly endless riding opportunities.

Bike Park Stats
  • Dercum Summit: 11,640 feet
  • Base Elevation: 9,280’
  • Vertical Drop: 2,360’
  • Number of Trails: 55
  • Miles of Trails: 55


Beginner and Intermediate Trails

Downhill biking is a blast at Keystone. The bike park crew have been working hard to widen trails, add countless new berms for a flowier ride and even built a new beginner, learning zone at the base. Be prepared for some long rides up on the mountain. Single-track, dirt trails that includes open and forested areas, some rocks and tree roots make up our green trails. Blue trails have steeper grades, larger rocks and roots, tabletop features and requires good mountain bike skills.

Expert Trails
Keystone offers Colorado’s most exhilarating downhill challenges with rock gardens, rock drops and high-speed jumps. And our bike park crew have been working hard to add even more improvements, including new berms, more jumps and a new beginner, learning area at the base of River Run Gondola.

It's a progressive skills park for all abilities, it has a black jump trail, a blue jump trail, and a green trail, with rollers that the beginners love, as well as the experts. There is also a small skills park with logs, rocks, and rollers.

Drop Zone

Located off the Paid-in-Full trail, the Drop Zone consists of a series of ridgeline drops transformed into free falls:

Alley 1 
Piranha, Barracuda and Jaws - three ramps - ranging from a small 5-foot drop to a 14-foot drop that allows you to launch up to 22 feet.

Alley 2 

Paranoid - Rock drop with a natural take off and narrow wooden landing between the trees.

Alley 3 

Voodoo - Rock garden into a North Shore.

Alley 4 

Witch Doctor - North Shore feature launching you straight into the air ending with a G-Out (a natural landscape feature shaped like a berm ending in a straight and steep downhill run out).

Safety Information

Rules of the Trail:

No uphill traffic except on the summer road.
Pedestrians must stay off of bike trails.
Keep dogs on leash

1. Ride Open Trails:  Respect trail and road closures — ask a land manager for clarification if you are uncertain about the status of a trail. Do not trespass on private land. Obtain permits or other authorization as required. Be aware that bicycles are not permitted in areas protected as state or federal Wilderness.

2.  Leave No Trace: 
Be sensitive to the dirt beneath you. Wet and muddy trails are more vulnerable to damage than dry ones. When the trail is soft, consider other riding options. This also means staying on existing trails and not creating new ones. Don't cut switchbacks. Be sure to pack out at least as much as you pack in.

3.  Control Your Bicycle: 
Inattention for even a moment could put  yourself and others at risk. Obey all bicycle speed regulations and recommendations, and ride within your limits.

4.  Yield Appropriately: 
Do your utmost to let your fellow trail users know you're coming — a friendly greeting or bell ring are good methods. Try to anticipate other trail users as you ride around corners. Bicyclists should yield to other non-motorized trail users, unless the trail is clearly signed for bike-only travel. Bicyclists traveling downhill should yield to ones headed uphill, unless the trail is clearly signed for one-way or downhill-only traffic. In general, strive to make each pass a safe and courteous one.

5. Never Scare Animals:  Animals are easily startled by an unannounced approach, a sudden movement or a loud noise. Give animals enough room and time to adjust to you. When passing horses, use special care and follow directions from the horseback riders (ask if uncertain). Running cattle and disturbing wildlife are serious offenses.

6.  Plan Ahead: 
Know your equipment, your ability and the area in which you are riding and prepare accordingly. Strive to be self-sufficient: keep your equipment in good repair and carry necessary supplies for changes in weather or other conditions. Always wear a helmet and appropriate safety gear.

Lift Safety
Under Colorado law, you cannot board a lift unless you have sufficient physical dexterity, ability and knowledge to negotiate or to use such lift safely or until you have asked for and received information sufficient to enable you to use the lift safely. You may not use a lift when under the influence of drugs or alcohol. Please lower the bar when riding lifts.

Be aware that trails and roads on Keystone Mountain are used for many purposes during the summer. Mountain bikes, hikers, horses, motorized vehicles, construction equipment and others may be encountered at any time.

Construction Warning
You may encounter construction equipment, maintenance vehicles or other heavy machinery at any time. Always be cautious and obey posted signs and warnings.

Mountain Biking
Helmets and sturdy shoes with good tread are recommended at all times. Child carriers or tow-behind bikes are not permitted and all bikes must have two working brakes. All loose clothing, bags or packs should be firmly secured so they do not interfere with the bicycle’s moving parts.
Mountain bikers must always yield to other non-motorized trail users. Should you encounter hikers or horses on any trail, you must yield the right-of-way. Ride on designated trails only and obey all posted signs and warnings. Failure to do so may result in lift ticket and/or pass revocation.

Do not litter or feed wildlife. Hikers rarely encounter bears but, if you do, please remain calm and back away slowly. Keystone asks that everyone is cautious and respectful of wildlife.

Accident or Lost?
Retrace your steps or proceed downhill until you come to an emergency phone located in a bright red box. Call extension 4000 or 970-496-4000 from a cell phone.

Lightning or Thunderstorms
Lifts may close on occasion causing delays. Brief afternoon thunderstorms are common in the mountains. Seek shelter when you see a storm developing. You are responsible to take the proper precautions to include keeping of ridge lines and staying clear of chairlift houses and towers, power lines, open spaces, lone trees and sign posts. Please take this into consideration when planning mountain activities.

Mountain Bike Preparation
Temperatures ranges from 80 degrees Fahrenheit during the day to 40 degrees Fahrenheit at night. Swings in temperature can be drastic in short periods of time.
  • Sunscreen/lip balm
  • Sunglasses
  • Helmet
  • Windproof fleece or wool sweater/jacket
  • Waterproof jacket
  • Sturdy shoes with good tread
  • Water and energy food
  • Biking gloves (recommended)
  • Secure all lose clothing or bags
High Altitude Awareness
Above 8,000 feet, altitude illness affects 20 percent to 30 percent of visitors from low elevations to some degree. Upon arrival in this area, take it easy for the first day or two. Drink two or three times more water or fluid than usual. Limit alcohol consumption for two or three days and minimize caffeine intake. Limit salty foods and increase carbohydrate consumption. Most importantly, listen to your body. Do not push the limits of your physical capabilities.

Common Symptoms of Altitude Sickness

  • Shortness of breath when exercising.
  • Faster Heartbeat
  • Nausea
  • Unusual Tiredness
  • Headache
  • Difficulty Sleeping
Those with one or more of these symptoms may have Acute Mountain Sickness (AMS). If the symptoms do not subside shortly, a doctor should be called.
