About visiting Colorado
Colorado National Monument is a National Monument in CO and a moderately visited park, drawing about 483,000 recreation visits in 2025. Visitation has climbed over the past decade, up roughly 23.5%, so crowds are trending heavier each year. Crowds concentrate sharply by season: May is the busiest month at about 1.3× the park's average month, while February is the calmest at roughly 0.6× — a 2-to-1 swing between high and low season. Roughly 32% of the year's visitors arrive in the three summer months of June, July and August alone, so timing a trip outside that window is the single biggest lever on how crowded the park feels. Weather swings from an average high-season warmth near 79°F in July down to about 30°F in January, with the wettest stretch in September. About 7 months a year see comfortable average temperatures in the 50–80°F range, which is part of why crowd timing and weather timing don't always line up. The sweet spot is October: the lightest crowds of the park's good-weather months. Visit then and you trade a little peak-season certainty for noticeably shorter lines and easier parking than the May rush. Daylight ranges from about 9.3 hours in midwinter to 14.7 hours near the summer solstice, which shapes how much ground you can cover in a day. A standard private-vehicle entrance pass runs about $25, valid for several days, so a shoulder-season trip stretches that fee across quieter, more comfortable days. These crowd figures are drawn from 1979–2025 of National Park Service visitor-use records, paired with 1991–2020 NOAA climate normals, and are updated as new monthly data is released.
Park overview

Towering monoliths exist within a vast plateau and canyon panorama. You can experience sheer-walled, red rock canyons along the twists and turns of Rim Rock Drive, where you may spy bighorn sheep and soaring eagles.
