There are a lot of free things you can do in a state like Colorado. You can camp under the brightest stars or hike up the highest peak, without ever dropping a dime.
And if you remember these dates, you can save some money on seeing these normally paid attractions. From national parks to world-class museums, Colorado offers complimentary admission on regular dates throughout the season, each and every year. Get free entry all day at the Denver Zoo, Botanic Gardens, Art Museum, Museum of Nature & Science, and Colorado’s four National Parks.
Dates are subject to change. Here are the Free Days in 2022 at Denver Area Attractions:
