    Hike or Bike the Walker Ranch Loop

    4.7
    7.7 mi / 1740 ft gain
    When it comes to hiking trails in Boulder, the standard response usually consists of either Chautauqua Park or Mt. Sanitas, and while both offer excellent hiking options, they are both usually jam packed on the weekends. If you’re looking to stay close to the city, but want a little more seclusio...

  • Golden, Colorado

    Hike the Elk Range Trail

    2.5
    This is an incredible and beautiful hike that is just off of Route 6 but feels a million miles away. Drive up Douglas Mountain Road for the west park access (and I do mean UP - it's a quick elevation gain), and you'll run right into the Centennial Cone Park entrance. There is a bathroom and a dec...

    South Willow Falls

    Start at the Willowbrook Trailhead. You’ll hit a “Y” in the trail pretty quickly - go left and you’ll soon be at the first log bridge.

    Storm Peak and Mount Lady Washington

    4.5

    This adventure began at the Longs Peak trailhead in southeastern Rocky Mountain National Park, Colorado. I followed the Longs Peak trail for 6 miles to the Boulderfield backcountry camping area. This is a fairly steep on-trail climb of 3,360 feet. After setting up camp at 12,760 feet, my partner...

    Hike the Red Rocks Loop Trail

    3.7
    1 mi
    Parking is available on either Canyon or Sunshine Roads. During the weekends it tends to get crowded around sunset so plan accordingly. The entire trail is a loop and is a little over 1 mile in length so it doesn't take too long. The main feature is the massive red sand stone rocks that jut out o...

    Mount Sanitas Loop & Settlers Park

    4.4
    3.83 mi / 1371 ft gain
    First off, these are two different hikes but both stem from the same parking lot and Settlers Park is a mere 5 minutes away from where you park so why not kill two birds with one stone? One of the more popular hikes in Boulder, Mount Sanitas is a 3 mile hike that quickly scales nearly 1,350 feet...

The hike to Nymph Lake is an easy hike just over 1 mile. You start from the Bear Lake Trail head and can go further on to Dream Lake and Emerald Lake if you want to. Both Dream and Emerald Lakes are also stunning and very photog...

    Woods Quarry via NCAR

    4.2
    3.28 mi / 755 ft gain
    You can start from Chautauqua Park, but I prefer to start at NCAR, especially since there is ample parking and you can take a bathroom break inside before hitting the trail. From the intersection of Table Mesa Drive and Broadway in Boulder, drive west on Table Mesa to its end at the NCAR buildin...

    Hike Bear Peak

    7 mi / 2810 ft gain

Wake up early to start this hike.Even though the Bear Peak hike will only take you about 4-5 hours round trip, it will still be advantageous to get off the mountain before afternoon and evening storms might pass through. This is a steep 7-mile out and back trail.St...
