Rocky Mountain National Park encompasses more than 250,000 acres and boasts 124 named mountain peaks. Subsequently, the massive park draws visitors interested in camping, biking, fishing and horseback riding, among other outdoor activities. If you're not an outdoorsy type, consider a scenic drive or a picnic to make the most of the outstanding views. Winter activities like cross-country skiing, snowshoeing and sledding keep a flow of travelers visiting the park during the chillier months. The park's wildlife, which includes elk, bighorn sheep and moose, roam the verdant forests and glittering lakes, guaranteeing that every trip to Rocky Mountain National Park will be memorable.

One of the park's biggest draws is its collection of approximately 355 miles of trails. Avid hikers recommend the difficult Sky Pond via Glacier Gorge Trail, which runs about 10 miles and becomes more rewarding as you climb upward. For a more manageable hike, visitors suggest the roughly 3-mile Emerald Lake Trail. If you choose to tackle this trail, plan to arrive early in the day to beat the daily crowds that descend on the trail. For first-time hikers, travelers recommend the 2-mile Dream Lake Trail, a scenic out-and-back route that will prove manageable for most fitness levels.
