South Boulder Creek Trail

Lovely views of mountains and rural countryside

March, 2026 by laurastark

Our family took a springtime bike ride on the southern section of the South Boulder Creek Trail from the Bobolink Trailhead on Baseline Road south to just beyond the US 36 underpass (roughly 3 miles one way). It was a pleasant outing with gorgeous mountain views and rural countryside. We saw a few birds, a couple horses, and lots of cows (including calves). The trail surface was a mix of pavement and crushed stone; both well maintained. On a sunny Saturday afternoon, we saw lots of other bikers, joggers, dogwalkers, and families out enjoying the trail.

Bear Creek Trail (Denver)

Detour Central

March, 2026 by dcselfe2020

I have ridden this trail in its entirety hundreds of times in the last 20 years and appreciate some of the widening that has been done in some of high traffic areas. However, over the last year two bridges have been closed, and most recently another section has been closed east of Federal Blvd. One of the detours utilizes bike/pedestrian and is a minor inconvenience. The other two detours route you on side streets and then narrow sidewalks along busy 4 lane roads. If/when these issues are resolver it will go back to being one of my favorite routs, but until then I am avoiding it.

Boulder Creek Path

Everything is very good except because in some parts there are homeless people sitting or lying on the road where it is supposed to be for bicycle traffic!

State Highway 93 Trail

An unexpected delight

September, 2025 by laurastark

We begin our ride on the State Highway 93 Trail on its northern end at Golden’s North Table Mountain Park (the park’s West Trailhead). The park is in a beautiful area with other (unpaved) trails to explore. We rode this trail for about 1 mile south to its connection with the Tucker Gulch Trail (near the intersection of Mesa Drive and Joseph Circle) and enjoyed both trails. Although the State Highway 93 Trail parallels the roadway, there’s a nice median in between with native grasses and wildflowers, as well as the occasional wall, so the experience felt safe and pleasant.

Tucker Gulch Trail

Pleasant route through Golden's northern neighborhoods

September, 2025 by laurastark

We begin the Tucker Gulch Trail on its northwestern end at a connection with the State Highway 93 Trail (near the intersection of Mesa Drive and Joseph Circle in Golden). From there, we headed southeast, through Norman D. Memorial Park, quiet neighborhoods, and scenic natural areas until reaching the Golden Freeway underpass. It was just over a mile of riding and a very pleasant experience.

Signal Ditch Trail

Nice ride through Thornton

September, 2025 by laurastark

We enjoyed the northern tip of the Signal Ditch Trail on an early September ride. It was a pleasant neighborhood setting beginning from Thornton's Fallbrook Park. The journey included views of large cottonwoods, bright sunflowers, and the Rocky Mountains in the distance.

Grange Hall Creek Trail

Scenic ride through Thornton

September, 2025 by laurastark

We biked a section of the Grange Hall Creek Trail in Thornton from Margaret Carpenter Park through the south end of Grange Creek Park and into the Riverdale Open Space. It was a really pleasant ride through a beautiful natural setting and a prairie dog habitat.

Rainbow Trail

Great neighborhood pass through trail

July, 2025 by rbjones467

Rainbow Trail is a great stress free connector from the Arvada firefighters Park to the east rainbow park in North Arvada. Nice wide well maintained concrete trails. Mostly passes in between fences of houses on each side of the route but with ample trees. Great way to get to King Soopers (80th & Wadsworth) from the West End of Arvada.

Bear Creek Trail (Colorado Springs)

Pretty trail

July, 2025 by s2xc96nht8

Not too difficult, but there’s a pretty good incline hill in the middle of the route. You’re rewarded with a beautiful view of the park and surrounding Colorado Springs once you reach the top of it. Couple of intersections with creeks and a few options to swap up your route.

Fountain Creek Regional Trail

South Start: Start at Grinde Drive or Duckwood Trailhead

July, 2025 by robmidgley

Started a second time at Duckwood & rode down to the closed bridge, then north 5 miles before turning back. Wanted to do the full length but we lost too much time with the earlier start point. This portion of the trail is in constant use and great condition. Will absolutely be back to get the full ride north!

Fountain Creek Regional Trail

Do not start from the southernmost point!

July, 2025 by robmidgley

Tried to ride the full length starting at the south access point just south of the vacant office building. The trail is becoming overgrown, then blocked by a massive deadfall tree, which leads to some bushwhacking, just to find the trail no longer connects to the bridge due to river erosion. Rode back out to the road and our car on the access road just north of the abandoned office building.

South Platte River Trail

Calm and collected from the conference

June, 2025 by daraniashley

I rode this trail while in town for a conference and it did not disappoint. Use the lime bikes too. It was peaceful.
