Looking for a longer bike ride near Denver that doesn’t require committing to a mountain-bike trail? The Big Dry Creek Bike Trail is a multi-use route through Westminster and Thornton, just north of Denver. With connections to open space, parks, Standley Lake, and other regional trails, it gives travelers plenty of flexibility to plan anything from a shorter outing to a much longer ride.
For Rainbow Rentals guests staying in the Denver metro, this is the kind of outdoor activity that can fit nicely into a day of exploring without taking you deep into the mountains. Here’s what to know before you go.
The Big Dry Creek Trail follows the Big Dry Creek corridor through Westminster and continues into Thornton. Westminster describes its portion as nearly 12 miles, running from Standley Lake Regional Park toward Interstate 25 and beyond into Thornton. Colorado’s official COTREX trail system currently lists approximately 15 miles for the combined Westminster and Thornton route.
The trail is part of Westminster’s regional trail network and has been designated a National Recreation Trail since 2003. Much of the route travels through open space and parkland, with underpasses carrying the trail beneath many streets.
That makes the route particularly useful for travelers who want to get outside without building an entire vacation day around a difficult backcountry ride.
One of the biggest advantages of the Big Dry Creek Bike Trail is flexibility.
You don’t have to ride the entire route to enjoy it. Because the trail runs through several sections of the north Denver metro and connects with other trails, you can choose a starting point and turn around when you’ve had enough.
The route also gives riders a different perspective on the Denver metro. Instead of spending the day on city streets, you’re traveling through open-space corridors and along the creek, with access to nearby parks and recreation areas. Westminster says its trail system provides connections to local and regional parks, open space, neighborhoods, and other city amenities.
For visitors, that makes the trail a practical option for:
One important caveat: the official sources reviewed for this guide do not publish a current bike-specific difficulty rating for the entire route. Rather than labeling the whole trail “easy,” check your intended section and current conditions before setting out.
COTREX currently lists the Big Dry Creek Trail as allowing bicycles and reports a mix of surfaces, including approximately 8.4 miles of concrete and 7 miles of gravel across the mapped route.
That detail matters when choosing a bike.
For a mixed-surface route, a comfortable recreational, hybrid, gravel, or similar bike may be a better match than assuming every section is a smooth paved pathway. If you’re renting, tell the rental provider that you’re planning to ride the Big Dry Creek Trail and ask what bike they recommend for the specific section you intend to ride.
If you’re traveling with children, it’s also worth planning your ride around the family’s comfort level rather than treating the trail’s full mileage as the goal.
Standley Lake Regional Park is one of the most recognizable access points associated with the western end of the trail. Westminster identifies the trail as running from Standley Lake toward I-25 and beyond into Thornton.
Standley Lake also has free parking options specifically serving walk-in and bicycle access. The city lists free lots at 86th Parkway and Simms Street and 100th Avenue and Owens Street. Those lots close at sunset.
If you’re driving into Standley Lake itself, note that the city currently lists a daily vehicle parks pass at $7, while walking or riding a bicycle into the park does not require an entry fee.
Because access rules, fees, and parking arrangements can change, check Westminster’s current park information before your ride.
Yes. One of the appealing things about riding in this part of the Denver metro is the larger trail network.
Westminster identifies five major regional trails in its system, including Big Dry Creek Trail, Little Dry Creek Trail, Farmers’ High Line Canal Trail, Rocky Mountain Greenway Trail, and the U.S. 36 Bikeway.
The Big Dry Creek route also connects with the broader Rocky Mountain Greenway system around Standley Lake.
For visitors, the takeaway is simple: you can plan a ride around the distance your group actually wants to cover instead of feeling like you need to complete one fixed route.
Before heading out, use the current COTREX and city trail maps to confirm your intended route and any connections.
If you’re visiting Denver without bringing your own bikes, you have a few options to investigate.
One particularly relevant option is No Stress eMountain Bike Tours & Rental, which advertises e-bike rentals and says it can bring bikes directly to customers. Its current website lists adult mountain e-bikes and says rentals include a helmet, lock, and water bottle. The company is based in Westcliffe but advertises Colorado-wide delivery, so travelers should confirm that delivery to their Denver-area lodging or chosen trail access point is available before booking.
Another possibility for travelers staying in Westminster is checking with Origin Westminster, which currently advertises mountain bike rentals as a hotel amenity. This is a hotel service, so confirm availability and rental terms directly with the property before making plans.
The important thing is to reserve or confirm your bike before building your day around the ride. Rental inventory, delivery areas, bike sizes, and current pricing can change.
A good bike outing doesn’t require an enormous packing list, but a few basics can make the day easier.
Consider bringing:
Colorado weather can change quickly, so checking the forecast before leaving is worthwhile.
If you’re renting an e-bike or another unfamiliar bike, give yourself a few minutes to adjust the seat, understand the controls, and make sure the brakes and tires feel right before starting the ride.
The Big Dry Creek Trail can work well as a family outing when you plan around your group’s actual riding ability.
The biggest mistake would be treating the trail’s total mileage as a required distance. Instead, pick a manageable section, set a turnaround point, and leave room for breaks.
Because the route is part of a multi-use trail system, remember that you’re sharing the path with other users. Westminster specifically encourages trail users to follow its trail etiquette guidance as trail traffic increases.
For younger riders, stay alert around trail intersections and other users, keep everyone together, and make sure children understand basic trail etiquette before you start.
The trail can be incorporated into a Colorado trip during much of the year, but your exact experience will depend on weather and current trail conditions.
For a summer outing, an earlier start can help you avoid the hottest part of the day. In shoulder seasons, check the forecast and trail conditions before heading out, particularly if your planned route includes gravel sections.
Standley Lake’s access schedule also changes seasonally. Westminster currently lists walk-in access from sunrise to sunset year-round, while vehicle access has different hours in summer and winter.
If you’re planning a specific ride around sunrise, sunset, or a park visit, verify the current access information before you go.
The Big Dry Creek Bike Trail is a good reminder that you don’t always have to leave the metro area to add an outdoor adventure to your Colorado itinerary.

Rainbow Rentals currently offers Denver-area vacation homes in Westminster and Northglenn, including the Mid-Century Escape w/ Hot Tub & Arcade Fun in Westminster and the Spacious Denver Retreat w Hot Tub & Game Room in Northglenn.
Whether you’re planning a family ride, a longer cycling day, or simply want a change of scenery between Denver activities, check the current trail map, choose a section that fits your group, and make the ride part of the adventure rather than the whole itinerary.
Trail mileage, surfaces, parking, access rules, construction, and rental availability can change. Check the linked official sources before your visit.

Yes, travelers can investigate local rental options. No Stress eMountain Bike Tours & Rental advertises Colorado bike delivery, while Origin Westminster currently lists mountain bike rentals as a hotel amenity. Confirm current availability, delivery area, bike type, and pricing before booking.
It can be a practical family cycling option because it is a multi-use trail that allows bicycles, but the full route should not be treated as a required distance. Choose a section that matches your group’s riding ability and check current conditions before heading out.
