Hall Ranch Trails including Bitterbrush Trail and Nelson Loop Trail
Lyons, Colorado, United States (13.6 miles away)
Difficult: 5.9 miles, 1-3 hours
The Bitterbrush and Nelson Loop Trails are fairly difficult mountain bike routes that form a lasso trail near Lyons, CO.

Unlike many of my other trail guides, this one is definitely a little more strenuous and technical. If you are riding a bike, prepare for steep climbs and rapid descents. There are some tricky corners and numerous rocks and roots in the trail. There is also great scenery, lots of wildlife, and a heck of a roller-coaster ride. Although this trail is...

Moderate: 16.4 miles, 1-3 hours
Mountain bike trail west of Golden, CO

This is a relatively new trail that opened several years ago. It is about 10 miles west of Golden yet seems to be far more remote than its proximity to Golden. It offers great views over Clear Creek Canyon. Although not a technically difficult trail, there are some steep drops off of the trail where you may get hurt if you aren't paying enough attention...

Eldorado Springs, Colorado, United States
Hiking | 5.8 miles (5.9 miles away)
An easy hike, in a Colorado State Park.....Eldorado Canyon Trail.  Our goal to reach the Walker Ranch junction was cut short by distant thunder and lightning.  But we were rewarded with a trip to Agave Mexico Bistro & Tequila House in Boulder, and a stop at GoLite's warehouse sale.
