There are a huge number of National Forest roads in the Roosevelt National Forest that are excellent for off-roading. Red Feather Lakes is in the Canyon Lakes Ranger District of the Roosevelt. You can find the official Motor Vehicle Usage Maps for Colorado National Forests at the following link:

Please help us locals to keep these National Forest wheelin roads open to 4x4s by following the MVUMs as to which roads are open to the public. Paper copies of the MVUMs are also available at NFS ranger stations and at Jax ( a local sporting gear/outdoor outfitters store).

Some of my favorite trails in the Roosevelt National Forest are Storm Mountain and Crystal Mountain. A little further south is Middle Saint Vrain trail. If you want to head west of Walden to Steamboat Springs then you can go another 30 min north of Steamboat and check out the Hahn's Peak area.
All of these are trails I have done in a stock TJ with only dents to my skids to show for damage.
