This is a scenic spot to look out over the reservoir. The dam itself was built in the early 1960s and required relocating the original town of Dillon, which is now sitting beneath the water. Today, the reservoir holds Denverโs largest water supply and sends it through a tunnel under the Continental Divide. Surrounded by mountain towns, Dillon Reservoir is a popular locale for boating, fishing, and summer concerts at the lakeside amphitheater.

The bike path to and around the Dillion Reservoir is very scenic and peaceful. There are amazing mountain views almost everywhere around the water, and you can watch boats launching from the nearby marina.

This is the start to the Forest Troll trailhead. From here you can lock up your bikes and make the very short walk to the wooden troll that most visitors of Breckenridge make a priority to see. One huge benefit of riding your bike is that there is only paid parking here, but plenty of places to lock up your bike. In the winter, this trail can get slick from all the people packing down the snow and it turns to ice. If there is snow on the ground, shoe spikes are highly recommended, otherwise it is a literal ice rink with lines of people taking baby steps and sliding off into the woods.

Boreas Pass via Baker's Tank Trail is a shaded trail with exposed sections sprinkled throughout. If you ride to the end (or you can just drive there via Boreas Pass Road) you will be rewarded with the Baker's Tank historic site.

Grays Peak is one of Colorado's famous 14ers and one of the easier ones to summit. If you hike along the iconic Continental Divide Trail (stretching from Mexico to Canada), this mountain is directly on your route. As with all mountains in this area: Keep an eye on the weather. Thunderstorms in the afternoon are very likely during the summer months, so start your hike early. And since you are already here: With Torreys Peak, there is another 14er just around the corner.
