Last Updated on 24 Apr 2024 by Fiona Perisone

The Indian Peaks Wilderness in Colorado is an outdoor lover's dream and a hikers paradise! From the moment you set foot on the trails, you'll be transported to another world. With its breathtaking views, lush landscapes, and various trails, the Indian Peaks offers something for everyone. 

This magnificent wilderness area offers a variety of trails that cater to every skill level and interest. Whether you're looking for a scenic picnic spot, a challenging hike, or a peaceful place to fish, below, we will share everything you need to know about the Indian Peaks Wilderness area. 

About the Indian Peaks Wilderness

Situated within the Arapaho and Roosevelt National Forests, the Indian Peaks Wilderness became part of the National Wilderness Preservation System in 1987 and is a 73,391-acre protected slice of mountain majesty in Colorado's Front Range. It's sandwiched between the James Peak Wilderness to the south and Rocky Mountain National Park to the north. To the east, the slopes descend toward the Front Range Urban Corridor, where most Coloradans live.

The wilderness area has two distinct sides since it is draped over the Continental Divide, and no roads cross it from east to west. The eastern side is more popular due to its proximity to cities like Boulder and Denver. The western side is farther but is just as wild and spectacular as the eastern side.

Best Time to Visit

Embark on a journey through the breathtaking Indian Peaks Wilderness at any time of year, but summertime is when the magic truly shines. While June and July are prime months for exploration, June can present some challenges with lingering snow in higher elevations. By July, the snow had melted away, revealing crowded trails and pesky mosquitoes. For a truly unforgettable experience, plan your visit in August or September. Enjoy the crisp, dry air, bug-free hikes, and peaceful trails without the hustle and bustle of peak season. Although, be prepared for a refreshing chill in the air on some early mornings!

Experience the stunning beauty of Indian Peaks Wilderness at its finest by avoiding crowds. Plan your visit during the week or rise with the sun on weekends to beat the crowds for a serene escape. Although thunderstorms are common, they are not a daily fixture, leaving ample opportunity for clear skies and breathtaking views. Take advantage of a peaceful day by waking up before dawn and trekking above the treeline to witness a stunning sunrise. And as the day comes to a close, settle in for a breathtaking sunset behind the majestic peaks of the wilderness for a truly unforgettable experience.

Things to Do


Brainard Lake

The Indian Peaks Wilderness is packed with outdoor opportunities. The best way of seeing the highlights is via one of the region's many hiking trails. Mount Audubon, Isabelle lake, Lake Dorothy, and Gibraltar Lake are beautiful destinations on the east side of the wilderness. Crater Lake, Mount Irving Hale, Foxpark, and Corona Pass are beautiful destinations on the western side. In general, the trails on the western side are longer and tougher. Yet, the scenery is often more remarkable, especially in the Crater Lake region. There, vertical spires of rock seem to shoot straight into the stratosphere.

Embracing The Hues of Autumn

Autumn in South Indian Peaks Wilderness

As summer fades into fall, the Indian Peaks Wilderness transforms into a golden wonderland. The crisp air and golden Aspen trees paint entire hillsides in late September and early October, creating a natural canvas for the adventurous spirit. 


The Indian Peaks Wilderness is a fisherman's paradise, offering miles of pristine streams, alpine lakes, and scenic vistas. However, you may need to hike to some of the more remote ones. Cast your line in search of rainbow trout, brook trout, and cutthroat trout, or try your hand at catching the elusive native greenback cutthroat trout.

Eating Options

The best places to find food are in the towns nearest to the wilderness area. Nederland has the Crosscut Pizzeria and Taphouse, along with Busey Brews Smokehouse and Brewery. The town is east of the wilderness and close to the Hessie Trailhead, 4th of July Trailhead, Eldora Ski Resort, and Brainard Lake Recreation Area.

How to Get There

The easiest way to reach the Indian Peaks Wilderness is by approaching from the east. Colorado's largest (international) airport, DIA, is two hours from here. The Hessie and 4th of July trailheads and Brainard Lake Recreation Area offer the fastest way to get into the wilderness.

Keep in mind the places closest to the big cities will have the most crowds.

Golden Tips

All About Timing

As with many popular places, there are good and bad times to visit. Traditionally, the weekends from June through August will be the busiest, and you'll often encounter full parking lots by 7 am these days. There's a shuttle service for Hessie and 4th of July Trailheads, which helps.

Visit Brainard Lake Recreation Area Tip

Brainard Lake Recreation Area is arguably prettier, but there are fees and a reservation system in the summer. You will be ticketed if you don't have them. You can avoid these by parking at the Gateway Trailhead for free, but it will add five miles (2.5 each way) to any outdoor journey.

The East Side

A fun alternative on the eastern side is to visit the tiny town of Allenspark and find the trailhead for St. Vrain Mountain. It's a 7-mile effort with several thousand feet of elevation gain. But at the top, you'll be rewarded with stunning views of the iconic 14,259-foot Longs Peak.

The Western Side

On the western side, Monarch Lake is the most popular spot. The parking lot is large but can easily fill up on summer weekends. A nice strategy is to book a campsite at Arapaho Bay on the shores of Lake Granby. The campsites are only 10 minutes from the trailhead. If both areas are completely full, park at the Roaring Fork Trailhead.

Altitude-related problems

Altitude sickness can occur in any area over roughly 8,000 feet. If you have pre existing heart conditions, check with your doctor BEFORE traveling to high-elevation areas. For most, altitude-related problems come in the form of headaches and occasional nausea. You can treat them with fluids and ibuprofen (if you're not allergic). But if the symptoms don't go away, go down in elevation until you feel better.

Wild-Life Activity

Animal sightings are common, but in all cases, never approach wildlife. Wildlife can be unpredictable.

On The Watch For Winter Storms For Winter Visits

Winter is a subdued time for the wilderness but offers a ton of peaceful outdoor opportunities. Having said that, winter storms can be severe. Always check the weather and dress in multiple layers.

Road Condition

In the summer, only Brainard Recreation Area has paved road access. Hessie, 4th of July, Monarch Lake, Rock Creek, Roaring Fork, and Corona Pass are all dirt roads. Make sure you drive slowly, or you'll risk a tire puncture.

Winter closures also impact access. Dirt Roads close in the winter and remain closed for longer; some may not open until July. The Brainard Recreation Area's main road is closed at the Gateway Trailhead. Both Hessie and the 4th of July Trailhead are blocked by winter snow. But the road is plowed to within a mile of Hessie Trailhead, making winter adventures possible.

On The Watch For Thunderstorms In Summer Months

Summer thunderstorms are common, especially in May, June, and parts of July. The general rule of thumb is to be off of a summit and descending by noon unless the weather forecast says otherwise.

Wildfires Encounter

The most common time for them is during the dry months of August, September, and early October. If an area is closed due to a wildfire, do not venture into it.

Weak or No Cell Reception

Cell reception may not be available in all parts of the wilderness. If you plan to hike one of the many tall mountains here, make sure you have all ten outdoor essentials. Tell someone where you're going and when you expect to be back.

Overnight Permits

Overnight visits require permits, which you can obtain through the Boulder Ranger District Office or online. They go on sale for the year around March. The number of permits available is limited, so it is recommended that you obtain your permits in advance, especially during peak camping season.

Camping Sites

Not all campsites are open year-round. For example, the Four Lakes Backcountry Zone is closed for camping between May through November.
