According to the National Park Service, Rocky Mountain National Park has 355 miles of trails.
Hike to a spectacular waterfall, backpack into a picturesque alpine lake or climb to the top of a peak such as 14,259-foot Long's Peak. Before you set out on a trail, check the avalanche bulletin and reports. Be aware of weather conditions, and never hike alone. Steer clear of trails marked with avalanche signs.
Rocky Mountain National Park offers a variety of rock-climbing opportunities. The numerous peaks and granite formations provide plenty of opportunity to sport climb, boulder, ice climb, big wall climb and mountaineer. While Rocky Mountain National Park in Colorado is home to some of the classic long alpine rock climbs in the United States, its glaciated valleys also offer a lot of excellent bouldering.
Sport fishing is permitted in many of the park's alpine lakes and mountain streams. You can find a variety of trout species in the alpine lakes along with the park's native greenback cutthroat and Colorado River cutthroat trout. A Colorado fishing license is required for all individuals over the age of 16 to fish in the park.
Take a scenic drive from the lowland meadows and valleys to the highlands of the park. Drive through alpine forests and alongside mountain streams to gain amazing panoramas at over 12,000 feet.
Explore the snow-covered Rockies on cross-country skis or snowshoes. Take a ranger-led tour to get started with the basics of snowshoeing.
