GILLETTE (WNE) — Popular tourist attractions have been hit hard by the COVID-19 pandemic and Devils Tower is no exception.

The number of people who came to see the first U.S. national monument through September 2020 has decreased by 9.6% from 2019, from 426,111 in 2019 to 385,140 as of Saturday, according to the National Park Service.

A large part of that can be attributed to the pandemic. From March 25 to May 21, the park was closed to the public.

In September, however, Devils Tower had 74,135 visits, which is up 18% from September last year, according to the National Park Service.

The park’s hiking trails, climbing routes and picnic area are all open, but the visitor’s center and bookstore, and Belle Fourche Campground remain closed.
