Guanella Pass Hikes We Love

Guanella Pass is found in the Mount Blue Sky Wilderness (formerly called Mount Evans Wilderness) between the towns of Georgetown at the north end and the town of Grant at the south end, where US Hwy 285 intersects.

The Guanella Pass Scenic Byway totals 23 miles and follows an old wagon route that connected the mining towns of Georgetown and Grant, Colorado.

You’ll love exploring Colorado nature and wildlife in the heart of the Mount Blue Sky Wilderness, just outside of Denver.

We watched moose bathe in a small lake the morning we started on the trail leading to Mount Bierstadt (covered below).

Guanella Pass begins from the historic silver mining town of Georgetown and snakes up the mountainside. This smooth, paved road is easy to travel by vehicle from end of May through the later half of November.

Drive from Georgetown to Grant, where you can hop on US Hwy 285 and check out Kenosha Pass as well.

Keep your eyes peeled for mule deer feeding in meadows — and big horn sheep too — as you cut through spruce, lodgepole pine and aspen forests.

This scenic road hugs a beautiful creek and hits an apex of 11,700 feet. Enjoy the willows and Colorado wildflowers.

The Mount Blue Sky Wilderness borders the east side of Guanella Pass, which means there are several great hiking trails for summer, fall, and early winter. Only foot traffic is allowed on the pass in winter, as winter weather shuts the road down in late November.

While this post is all about Guanella Pass hikes, know that cross country skiers and snowshoers love this area too.

CoHH Parking Tip: Camping and parking on Guanella Pass is only allowed in designated spots marked with "Parking" and "Tent" symbols. Please only park in these designated parking areas. Have a plan B personal shuttle arrangement or a plan B hike if you show up and cannot find parking. When you park where you are not supposed to along the pass, it makes traffic even worse and could result in causing a crash. Please think of others!

Guanella Pass Hikes We Love

Hiking along Guanella Scenic Byway is popular since it’s not far from Denver. June through October are the best months, and remember the road is only open late May through late November, depending on weather.

Let me be frank - these trails and this byway is POPULAR. It’s best if you can go during the week and get to trailhead parking lots early (6 am!) in summer.

Hiking with your kids? Pull them out of school, and go during the week to miss the crowds. You’ll be glad you did!

While many of the trails below are long, challenging hikes, you don’t have to hike the entire route.

hiking abyss trail to helms lake

Abyss Trail in fall

Abyss Trail to Helms Lake

Distance: 12.6 miles Elevation Gain: 2,395’ Type: Out and back

Near Grant, Colorado, this Guanella Pass hike is popular and for good reason!

Now it might seem funny that we are sharing the longest, hardest hike first, BUT here’s why: For an easy hike, choose to wander just 2 miles in and turn around once you’ve had your fill OR hike nearly 2,400 feet all the way up to Helms Lake above treeline. Or, hike to treeline for amazing far-off views in so many directions.

Basically, you can choose between making this an easy, moderate, or hard hike, depending on how long you make your trek.

We hiked all the way to Helms Lake in September for some of the best aspen leaf peeping in Colorado. The far-off views of large golden aspen groves are tough to beat in the Mount Blue Sky Wilderness.

This hike starts off on an easy enough path winding through aspen groves and forest. Eventually you’ll hug a stream for a while, with some fun crossovers.

In summer, the wildflowers are popping, and in fall, the leaf peeping is phenomenal within the groves and at tree-line.

Burning Bear Trail is another easy Guanella pass hike to check out.

Beginner Hiking Tips

Wildflowers like Indian Paintbrush are plentiful on Guanella Pass

This is a popular backpacking trail and dogs are allowed on leash. In the fall, save this Guanella Pass hike for a week day to avoid the crowds. Leaf peeping is at it’s peak here around the end of September to early October.

Where to hop to after the hike: The Shaggy Sheep in nearby Grant, Colorado came highly recommended by locals. Serving up a small menu of Mexican inspired dishes, they also make great cocktails. Grab a mimosa and then take a hand pie to go! NOTE: Check their hours (7am-3pm in the summer) and they do not serve breakfast in the winter. 50455 US Hwy 285 in Grant, Colorado.

Or drive a bit further to Bailey for a treat at Aspen Peak Cellars Winery - a lovely restaurant with indoor and outdoor seating right on the North Fork South Platte River. Local wine paired with shareable charcuterie boards, plus to-die-for made-from scratch entrees served in a European atmosphere. They often have live local music too. 60750 US Hwy 285, Bailey CO 80421

Safety Precautions while hiking any Colorado Trail

  • Plan Ahead: Always tell someone know where you’re going and when you think you’ll return. Leave a note on your car seat with the information as well.

  • Pack Essentials: Carry plenty of water, food, warm clothing, a map, a compass, a first-aid kit, a flashlight or headlamp, and a whistle for eveyone in your group

  • Stay on Designated Trails: Heading out on your own can lead to getting lost and can damage the natural environment.

  • Check the Weather: Weather in mountainous regions can change rapidly. Make sure to check the forecast before hitting the trail and be prepared for all types of weather. Be ready to ditch your plans and choose another adventure for the day.

  • Know Your Limits: You know you. You know your physical limitations and when it’s time to turn around. Speak up when hiking with your friends and turn back if conditions are too challenging.

  • Stay Alert: Be aware of your surroundings, including wildlife, changes in the weather, trail conditions, and your own health.

Mount Bierstadt

Distance: 7.2 miles     Elevation gain: 2,736 feet      Type: Out and back

Summit of Mount Bierstadt in August

This challenging hike takes you up one of Colorado’s favorite fourteeners for newbies.

We spied moose bathing in the lake (0.6 miles in) before we began our ascent. The beginning of the hike includes sweet wooden bridges to carry you above the swampy places. But soon enough, you will be crossing the stream via a log. You’ve got this!

Don’t forget to stop and look up and enjoy the views as you make the climb! At about 1.7 miles in, the steep switchbacks begin. Then at 2.1 miles, the slope, or headwall, begins. At 2.6 miles in, you will begin to see the Sawtooth Ridge that connects Bierstadt to Mount Blue Sky.

The final quarter mile or so, you’ll begin to navigate boulders and make your way to the summit. Once at the top, enjoy the 360 views and snap some photos!

Climbing up Mount Bierstadt. The trail is easy to follow.

On a clear day, in addition to seeing Mount Blue Sky to the northeast, you can also make out two more fourteeners to the west: Grays and Torreys.

Don’t forget to pack your layers, a hat, plenty of water, snacks, and sunscreen.

Make sure you are ready for hiking in high elevation.
