It's fun to ride on the wooden planks - and when it's muddy, it helps you avoid the worst.

The "Waterton Canyon Recreation Area" trailhead sign here marks the Colorado Trail's Northern Terminus. It's a photo opportunity for thru-hikers continuing all the way south to Durango, a journey that stretches almost 500 miles.

Adler-Fingru Open Space is a 55.7-acre area that was once used for crop production and livestock grazing. Ownership of the space is divided three ways among the cities of Boulder, Louisville, and Lafayette. This property is under an agricultural lease, so access to the public is limited to only the Coal Creek Trail that passes through the space.

Warembourg Open Space is a peaceful spot along Coal Creek and the Coal Creek Regional Trail, shaped through conservation efforts by Boulder County, Louisville, and Lafayette. Established in 1999 and 2003, it offers hikers a lovely riparian habitat with cottonwoods, wildlife, and scenic creekside views—a perfect place for an easy, immersive walk close to nature.

You can see William Frederick Hayden Park on the right, and Denver on the left from Carl's Point. A perfect spot to take a mid ride photo or simply take a break and enjoy the view.

Pedaling along the Dakota Ridge service road, you’ll hit the famous Dinosaur Tracksite, where ancient footprints in Dakota sandstone are stained for visibility. Over 300 tracks left by iguanodonts and small theropods lie just off the path.
