Planning a trip to Colorado this summer? The snow is melting, the days are getting longer, and the Rocky Mountains are transforming into the ultimate outdoor playground.

But here’s the truth: if you just search for the “best things to do in Colorado in the summer,” you’ll likely end up stuck in I-70 traffic or waiting in line on a crowded, paved trail. To truly experience the wild side of the state, you need to get off the beaten path.

Living and guiding right here in the Front Range, I spend my summers dialing in the best climbing routes, gravel trails, and mountain peaks. If you want a real adventure, here is your ultimate local's guide to a Colorado summer.

1. Rock Climbing in the Front Range

If you want to experience the true scale of the Rockies, you have to get vertical. The Front Range is a world-class rock climbing destination, offering everything from accessible beginner routes to massive multi-pitch challenges.

• Where to Climb: Clear Creek Canyon offers incredible sport climbing routes directly over the river, while Eldorado Canyon is legendary for its towering sandstone walls.

• The Local Tip: If you don't have the gear or technical experience, hire a certified local mountain guide. Booking a guided rock climbing trip is the safest and most efficient way to learn the ropes, set up top-ropes, and get off the ground quickly.

2. Mountain Biking and Gravel Riding the High Country

Driving through the mountains is great, but riding them is better. Colorado boasts some of the best mountain biking and gravel riding in the country, featuring technical singletrack and endless high-alpine dirt roads.

• Where to Ride: Head to the high country. Destinations like Winter Park and Steamboat Springs offer world-class singletrack that cuts deep into the pine forests.

• The Local Tip: For gravel riders, explore the dirt county roads that connect historic mining towns. You’ll tackle massive climbs, encounter zero traffic, and discover panoramic views you simply cannot see from the highway.

3. Summit a Colorado 14er (The Smart Way)

Climbing a "14er" (a peak over 14,000 feet) is the quintessential Colorado summer activity. However, summiting a 14er requires physical endurance, mental grit, and a healthy respect for the altitude.

• Where to Hike: While peaks like Mt. Bierstadt or Quandary Peak are popular, they are often incredibly crowded. For a more isolated, authentic mountaineering experience, explore the rugged Sangre de Cristo range or the San Juan Mountains.

• The Local Tip: Start your hike in the dark. Summer in Colorado brings intense, lightning-heavy thunderstorms almost every afternoon. To stay safe, you must be off the summit and below the treeline by noon. Plan to be at the trailhead with your headlamp by 4:00 AM.

4. Earn Your Après-Adventure Beer

Colorado’s craft beer and culinary scenes are deeply intertwined with its outdoor culture. The best part of a 10-hour day in the mountains is the moment you take your boots off and celebrate the summit.

• The Local Tip: After a long day of guided climbing or high-altitude riding, find a local brewery with an outdoor patio. There is nothing quite like a cold craft beer and a massive burger after burning 4,000 calories in the alpine. Keep it casual—showing up in approach shoes covered in chalk dust is practically the local uniform.
