When to Hike Near Boulder

You can enjoy hikes near Boulder year round. In fact, you might even get lucky during the winter months, and be hiking on a beautiful, sunny day with 60-degree temps!

Hiking near Boulder isn’t so much about the time of year (you can learn more about what to expect during different seasons with my guide to hiking in Colorado). Instead, it’s about the time of day.

Hiking trails near Boulder get insanely crowded. And I mean full parking lots, hordes of people, and big groups of hikers. It may feel more like being in a city than out on a trail.

My biggest piece of advice? If you’re looking to go on a hike near Boulder, get there early! Trailheads such as the Hessie Trailhead, Chautauqua Open Space, and even Eldorado State Park area almost always full, especially on weekends.

If solitude is what you seek, then get to the trailhead before 7 am during the summer months, 8 am in the winter. If you want to hike on a weekend, be starting by 7 am to avoid big crowds.

Tips for Hiking Near Boulder

Boulder offers up amazing hiking trails for beginner hikers, all the way to the expert, long-distance trail runner. Regardless of your skill level, you’ll want to go into every hike, big or small, prepared. Here are a few quick tips for hiking near Boulder:

  • Check trail conditions and trail closures. These past few years a lot of hiking trails near Boulder have closed due to maintenance and upgrades, so check to make sure you can actually hike!
  • Check the weather. Colorado is known for some wild weather, so be sure to check local weather conditions before heading out.
  • Be prepared. Always take the proper hiking gear with you. Never leave home without the Ten Essentials. Colorado is super-dry so I like to leave an extra water bottle in the car and either driving slippers (with a sole) or sandals to treat my feet afterward!
  • Practice Leave No Trace. It’s okay to be new to hiking, but it’s not okay to trash the trails. Always pick up after yourself (this including packing out dog poop, toilet paper, and fruit peels).
