The San Juan National Forest has wonderful variety. You can be in the "low country" and enjoy the sagebrush/pinyon and juniper up head up to over 14000 peaks in the wilderness. The are great rivers, streams and lakes full of fish for fishing, rafting boating or just contemplating. Wildlife is varied and plentiful. The San Juan is not near any population center, so it is not overrun with people. It is easy to find solitude and you can spend all day and not see another person in some areas. Try that near Denver!
We love the trails and the back roads for sightseeing. The San Juan has a nice variety of user experiences from hiking, horse and biking non-motorized to motorized trail systems and jeep roads. There are many historical places to visit with a rich history of mining, ranching and skiing in the area.
