The Terry Badlands WSA includes colorful, banded cliffs that overlook rolling prairie.  Geologic features include sandstone bridges, spires, table tops, and buttes divided by many deep gullies all formed by thousands of years of wind and water erosion. Rolling benches are vegetated with grasses, wildflowers and brush such as sage, yucca, greasewood, and scattered juniper. One of the most easterly stands of limber pine is located in the WSA. Wildlife include mule and whitetail deer, pronghorn, elk, badgers, many raptors and reptiles such as horned lizards. Petrified logs may be encountered in the WSA. The WSA is high in cultural resources. Historical resources include 1800s era U.S. Army troops graffiti on Sheridan Butte. The WSA is an excellent area for hiking, back country hunting, rock and fossil collecting and enjoying the spectacular badlands scenery. 

Visitation Information

The Terry Badlands WSA is located in Prairie County, 3 miles northwest of Terry, MT. Travel on Highway 253, which is also the Big Sky Backcountry Byway, approximately 3 miles, where you will turn left or westbound on a gravel road. There are two vehicle trails in the Terry Badlands WSA.  One is the Terry scenic overlook along the northeastern boundary.  Access is 3 miles northwest of Terry, MT; north of the Yellowstone River.  From Terry, travel on Highway 253, north (which is also the Big Sky Backcountry Byway), approximately 3 miles, where you will turn left or westbound on a dirt road.  The cherry-stemmed road is about six miles long which brings visitors inside the WSA.   This area is signed once you are in the WSA, you can pull over along the road and park to, traffic is light.  The second vehicle trail is the Calypso Trail, which bisects the WSA from the southeast to the northwest.  To access the Calypso trail, one travels west out of Terry on Old Highway 10 for approximately 2  miles, turn right, or westward, on Milwaukee Road for a little over three miles, then drive over a one-lane bridge across the Yellowstone River, also the Lewis and Clark National Historic Trail, which originally served as a Milwaukee Railroad bridge. A kiosk about a half mile past the river gives information about the area and marks the beginning of the Calypso Trail.  You can travel up the Calypso Trail (4 wheel drive recommended) and again pull over along side the road (in areas that make sense of course - not on a hill, etc.) to park and walk.  Once you are in the WSA it is signed.  There are no designated parking areas.  Do not drive off road.
