Polar Mesa trail is a short 10 mile spur off of the Castleton-Gateway Road that takes you up to the top of Polar Mesa where there are some old uranium mining ruins. There are also a great views over Fisher Valley and the Dolores River valley.
There are numerous side trails in this area that can be explored. Some of them may be more difficult and less traveled than the main route, which is generally pretty easy with a few bumpy sections.
