IDA-certified granite spires — cool climate, dark Great Basin sky.
Updated: · Tonight: Friday, August 14, 2026
City of Rocks is a granite-spire wilderness on the Utah–Idaho border, famous with rock climbers by day and, since gaining official Dark Sky Park certification in 2023, increasingly known for its night skies too. There's no electricity in the reserve and very little light anywhere nearby, so the Milky Way looks much as it did to travelers on the historic California Trail that once passed through.
