Top 10 Must-See Attractions
These are the unmissable experiences that define any visit to Colorado.
Rocky Mountain National Park
One of America's most visited national parks featuring dramatic alpine scenery, abundant wildlife including elk, moose, and bighorn sheep, and over 350 miles of trails. Trail Ridge Road reaches 12,183 feet making it the highest continuous paved road in the US.
Mesa Verde National Park
America's only UNESCO World Heritage Site dedicated entirely to archaeology, Mesa Verde preserves over 600 ancient cliff dwellings built by Ancestral Puebloan peoples. Cliff Palace is the largest cliff dwelling in North America with 150 rooms and 23 kivas.
Red Rocks Amphitheatre
One of the world's most iconic outdoor concert venues, Red Rocks is carved into naturally occurring red sandstone formations that provide perfect acoustics. Even when no concert is scheduled, the park is open for hiking with spectacular views of Denver and the plains.
Garden of the Gods
A stunning free public park featuring dramatic red sandstone rock formations rising up to 300 feet against a backdrop of snow-capped Pikes Peak. The park has 15 miles of trails, a free visitor center, and is one of the most photographed places in Colorado.
Great Sand Dunes National Park
Home to North America's tallest sand dunes rising 750 feet above the San Luis Valley floor, with the dramatic Sangre de Cristo Mountains as a backdrop. The unique landscape includes a seasonal creek, conifer forests, and alpine lakes just beyond the dunes.
Maroon Bells
The most photographed mountain scene in Colorado, the Maroon Bells are two peaks over 14,000 feet perfectly reflected in Maroon Lake. Surrounded by the Maroon Bells-Snowmass Wilderness, the area offers world-class hiking and fall aspen foliage.
Black Canyon of the Gunnison National Park
One of America's most dramatic yet lesser-known canyons, Black Canyon features walls dropping 2,700 feet to the Gunnison River below. The canyon's dark Precambrian rock and narrow width (1,100 feet at its narrowest) create an awe-inspiring landscape.
