Embark on your exciting excursion along the Boulder Reservoir Loop Trail from the North Trailhead off N 55thStreet. From here, the loop can be completed from either direction, but we prefer trekking counterclockwise along this route. The initial segment of your hike will be along the roadside of N55th Street. Departing from the trailhead, keep right along the road and over a small stream. As you hike west you will be granted expansive views of the Front Range peaks and foothills that flank the cityscape, including the famous flatirons. Enjoy the stunning mountain views as you trek, and the path will begin to curve you south. Now near the shoreline, you will be granted an up close and personal view of the shimmering waters.

Crossing yet another stream, divert off the road and trek the access route through the southwestern entrance to the recreational area. Track east along the shoreline, passing the designated swimming area and boat rental shop. Eventually, you will merge onto the Boulder Reservoir Dam Trail South. Now closely hugging the shoreline you will notice all the paddlers and kayakers enjoying the waters. Follow this path, passing the water treatment plant. Soon after passing the plant, you will encounter an intersection, keep left and you will be diverted onto the Boulder Reservoir Dam Trail North.

Follow this route along the eastern shore of the reservoir up to Coot Lake. This area of the hike passes through wetlands so keep an eye out for osprey, herons, and raptors. Continue along this trail which will guide you west over another stream. Soon the path will deliver you back to the trailhead, marking the end of your Boulder Reservoir Loop Trail experience. If you have some spare time, consider renting a paddleboard and enjoy the reservoir from a different perspective.
