About visiting City Of Rocks
City Of Rocks National Reserve is a National Reserve in ID and a relatively quiet park, drawing about 91,000 recreation visits in 2025. Visitation has eased over the past decade, down about 23%. Crowds concentrate sharply by season: June is the busiest month at about 2.0× the park's average month, while February is the calmest at roughly 0.1× — a 20-to-1 swing between high and low season. Roughly 45% 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 72°F in July down to about 30°F in December, with the wettest stretch in May. About 6 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 June rush. Daylight ranges from about 8.9 hours in midwinter to 15.1 hours near the summer solstice, which shapes how much ground you can cover in a day. These crowd figures are drawn from 1992–2025 of National Park Service visitor-use records, paired with 1991–2020 NOAA climate normals, and are updated as new monthly data is released.
