Directions & Transportation

A large bighorn sheep ram crosses a highway, with vehicles safely stopped in their lanes.
Although it may seem strange, at times, wildlife have caused traffic jams along Highway 16 leading to the monument.

Where is the monument?

Jewel Cave National Monument is located about 13 miles west of Custer, South Dakota and 24 miles east of Newcastle, Wyoming along Highway 16. Driving times vary by the season, weather conditions, road construction, and additional travelers during the summer months. For planning purposes, it takes approximately 25 minutes to drive from Custer to the monument and about 40 minutes from Newcastle.

Do not rely on GPS directions to navigate to the monument. Vehicle navigation systems have often taken guests past the visitor center and sometimes routed individuals onto backcountry roads that may be impassable to some vehicles.


Shuttle Service

Although multiple buses and tour companies operate in the Black Hills, there are no formal shuttles or public transportation to and from the monument.

Plane

Rapid City Regional Airport is the largest airport in the region and is 63 miles away. It takes approximately one hour and 30 minutes to travel from the airport to the monument.
