At 3.9 miles long with approximately 1,500 ft elevation gain, this hike around Hogback Ridge Loop twice really packs a punch. It is a great option if you want to get in a quick workout with a substantial amount of elevation gain.
Grindstone Quarry Trail, an easy 2.8-mile trail, was one of my favorite hikes at Heil Valley Ranch until it was burned in October by the Calwood Fire. Looking back at these pictures breaks my heart a little, thinking that when this trail opens up, it will look very different. However, I look forward to the day when I can hike this and other trails at Heil Valley Ranch when they open up again, and when the vegetation grows back over the years.
The Aspen Alley hike is just over 2 miles long with less than 200 ft elevation gain. This easy, family-friendly, hike features aspen trees along the central trail that turn beautiful golden yellow before they shed their leaves for winter. It is a great spot to take seasonal photos with the aspens.

This 8.5-mile, 1,450 ft-elevation gain moderate hike may be less well-known than other hikes in the Front Range, but it features some lovely and different views from other areas. In particular, the views of the valley, Mahoney Park, and the mountains beyond to the West were great.
The 7.3-mile option of hiking Mt. Sanitas via Sunshine Canyon and Lion’s Lair Trails out-and-back is now one of my favorite hikes in Boulder. You get the elevation gain of hiking Mt.

It can be a refreshing hike on a summer morning, as you pass through shaded forest areas along the way.
The Coulson Gulch Trail to Ralph Price Reservoir hike is 6.5 miles out-and-back. It features shady forest by a creek, meadows with mountain views, and a view of a large reservoir at the end. The hike goes downhill on the way out, and uphill on the way back.
