The monument is open year-round. The climate and seasons at Devils Tower echo those in the Black Hills region. Summer days can be hot and dry, although thunderstorms are not uncommon; evenings and early mornings are usually damp and cool. Spring weather is often chilly and rainy, and fall weather is often pleasant but can be cool and often cold at night. Winters are usually cold, but snow and sunlight can combine to create incredible pictures of the landmark.
Avoiding the Crowds
Traffic patterns at the monument are similar to those of national park areas throughout the West. Expect the highest visitation from June through August, with lower visitation in the shoulder months of April, May, September, and October; the lowest visitation is during winter. Parking is limited in summer.
If you visit during the summer, stop at the tower early in the day or take in a fireside ranger talk when crowds have thinned in the evening. Each year during the second week in August, a huge motorcycle rally takes place in nearby Sturgis, South Dakota. Attendance may significantly increase during that period.
