Mount Tarn is perhaps the most classic mountain in the region of Magallanes y Antártica Chilena. Climbed by trekking fans, mountaineers and some trail runners, it is a classic mountain today. Sharing trails with Cabo Froward and trekking to the San Isidro Lighthouse, Mount Tarn rises standing out in the area.

From the AT parking area on Under Mountain Road, follow the AT up and over Lions Head and Bear Mountain, and then take the Paradise Ln Trail which loops back around to the AT, and follow the AT back to the TH.  About 13 miles.
