The Elder-Fehn Trail falls within the Catamount Ranch Open Space owned by Teller County. It is part of a larger network of trails that lay on multiple recreation areas and ownerships, including The North Slope Recreation Area (owned by Colorado Springs), BLM land, and USFS land. Elder-Fehn itself has a lariat configuration and is 4.9 mi if you ride it out and back. The loop on the west end is 1.5 mi long. The trail connects to Limber Pine Trail on its east end and Vawhinger trail a little before the loop towards the west end.
The trail itself is mostly wide singletrack and is quite smooth with some roots here and there. There are short steep ups and downs throughout and several switchbacks along the way. It is generally more up on the way out and more down on the way back.
