Trail Overview

This trail is very easy when dry. It takes you through amazing scenery of the Terry Badlands. There are a few steep spots where it would be sketchy if conditions are wet. The trail consists of silty clay, and will turn to a greasy slick surface when wet. It's a very narrow trail with shallow drop-offs on either side. There is an old rickety railroad bridge from the 1900s that is required to cross to get to the Calypso Trail.

Trail was dry and easy. There are a few spots where you have to slow down and there are ruts and a small rock ledge. It is a beautiful trail. We even got to see some prairie dogs!

Trail was in pretty good shape. Views are fantastic. The Milwaukee railroad bridge coming in is open, but there is construction work set to begin sometime in the future so it may be best to call the BLM office in Miles City before heading to the trail. Gets pretty narrow in spots and there are quite a few blind corners. Couple of steep climbs but nothing too difficult. Most of the trail is fairly smooth and my gladiator could handle it in 2wd. Be mindful after rain though as the trail could get quite difficult with some mud. I throughly enjoyed how in a lot of places on this trail there were small hills to climb that when cresting over the top you were met with the amazing view of the terry badlands and how far it reaches.

The old Milwaukee railroad bridge is open for easy access to the Calypso Trail. The trail itself was very good, looks like it may have been recently bladed. Only saw 2 other vehicles.
