Hall Ranch Trails including Bitterbrush Trail and Nelson Loop Trail
Hall Ranch Trails including Bitterbrush Trail and Nelson Loop Trail
Lyons, Colorado, United States (10.3 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...

Boulder, Colorado, United States (11.7 miles away)
 
Easy: 7.1 miles, 1-3 hours
Enjoy America's #1 recreation town by bike. This path starts in the plains, goes through town and ends in the mountains.

In a town that loves its trails and alternative forms of transportation, the Boulder Creek Path is the perfect defining landmark.

This mountain bike version of the famous Morgul-Bismarck bike race course, is a great loop trail near Superior, Colorado

Also known as the "Happy Meal Loop," the Bismarck Dirty Loop was completed in 2011 with the addition of the Meadowlark Trail section. This trail is easily accessible by Colorado Front Range trail users and is an especially enjoyable mountain bike trail. Although challenging in a couple short sections, in general the Bismarck Dirty Loop is not a very...

Heil Ranch

Enjoy biking, hiking, or horseback riding on the Wapiti and Ponderosa Loop Trails at Heil Ranch northwest of Boulder.

Boulder has not been voted America's #1 Outdoor City for nothing. Heil Valley Ranch Open Space is one of the many reasons for Boulder's worldwide reputation. Although the name of this guide is Heil Ranch, the two trails featured here are the Wapiti Trail and the Ponderosa Loop trail. Together, they form what is known as a lasso trail. This trail...
South Boulder Creek Trail
South Boulder Creek Trail
Boulder, Colorado, United States (13.0 miles away)
 
Easy: 3.2 miles, 1-3 hours
Follow the beautiful South Boulder Creek past grazing cattle and spot wildlife of all kinds on this marvelous trail.

It's not easy being a trail on the edge of America's most fit community. You get a lot of use. But it's not just humans that make this trail popular. Critters of all sorts populate South Boulder Creek and its companion trail. It's not unusual to see deer, coyote, dogs, cows, geese, and many smaller birds. On this particular trip, the author of this...

This trail wanders through the communities of Louisville, Broomfield, and Lafayette, Colorado. Most of the ride is on open space trails, but portions of it also utilize Dillon Road and S. 120th Street. There are three good trailheads from which to access this trail, and each trailhead is in a different one of the three communities mentioned above....
Walker Ranch Mountain Bike Ride
Crescent, Colorado, United States (21 miles away)
Classic ride west of Boulder, CO

This is a classic ride west of Boulder, CO. It is mostly intermediate with some advanced sections. Follow Flagstaff Road for about 7.5 miles from Boulder and you will come to the Walker Ranch Loop Trailhead. But since I am based in Denver, I will describe the directions from the Crescent Meadows Trailhead off of Gross Dam Road. To get to the trailhead...

Eldorado Springs, Colorado, United States
Hiking | 5.8 miles (19.2 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.

Pleasant afternoon hike in Boulder, tougher because I'm not used to the altitude!  The Flatirons are very scenic.  I even spotted one wedding couple having their pictures made here.

We started out with our dog Buck and made it to the top in around 2 hours. As we arrived at the top we ran into two other girls, trying to make their way up. Eventually we all made it up and met two more climbers who had left the rope. After some pictures and chatting we all climbed back down the icy slope which proved to be more difficult then climbing...
