Best Hiking Trails Near Denver

Denver sits at 5,280 feet, and many trails go much higher. Altitude can cause shortness of breath, fatigue, and headaches. Drink extra water, take breaks, and give yourself time to acclimate. Start with lower-elevation trails if you're visiting from sea level.

Essentials include water (more than you think), snacks, sunscreen, hat, layers (weather changes quickly), first aid kit, map/GPS, and fully charged phone. Even on short hikes, conditions can change rapidly in the mountains.

It varies by trail. Many allow leashed dogs, but some (like Hanging Lake and Roxborough State Park) prohibit them. Always check specific trail regulations before bringing your dog.

Peak wildflower season is typically July-August at higher elevations, and June-July at lower elevations. Timing varies by year depending on snowmelt and rainfall.

Black bears, mountain lions, moose, and rattlesnakes live in the area. Make noise while hiking, keep dogs leashed, never approach wildlife, and know what to do if you encounter animals. Carry bear spray in bear country.

Some popular trails (Hanging Lake, Roxborough State Park, Rocky Mountain National Park) require timed-entry reservations. Check specific trail requirements before going. Many trailheads require parking passes.

Mountain thunderstorms are common in summer afternoons. Start hikes early (by 7am) to be off exposed ridges by noon. If caught in a storm, get below treeline, avoid open areas and tall objects, and wait it out in a safe location.

Lower-elevation trails are often accessible year-round, though they may be icy. Higher trails are typically snow-covered November-May. Winter hiking requires proper gear including microspikes or snowshoes.
