From the intersection of US 285 and US 160 in Monte Vista, CO, drive south on CO 15 for 2.5 miles and turn right (west) onto a road with three possible designations. Locally, this is "2 South West," aka: CR "R," or "The Rock Creek Road." Drive 2.5 miles west on paved road which will then make a sharp left turn back to the south. Continue 4 more miles with the road veering SW for a distance before heading back south. It will cross the non-designated Rock Creek at a local ranch where it turns to gravel, continues another half mile or so, then turns right (west) to roughly follow on the south side of Rock Creek. By this point, you are now on County Road 28 which eventually becomes a Forest Road of the same designation. You will be following this road to its end. After a few more miles crossing open prairie and ranch land, the road enters forest & canyon, climbs briefly over a low pass of sorts, then drops back down to pick up and follow the South Fork of Rock Creek. The road will pass two campgrounds as it continues up stream. The first will be the Rock Creek Recreation Area followed by the Comstock. These two campgrounds are just under three miles apart. Both are first-come, first-served. Neither has water but both have vault toilets. They can be open much of the year depending on snow conditions.
From the Comstock CG, continue along the South Fork of Rock Creek. The road will cross from the north to the south side of the creek and go up a switchback. It then will gain quite a bit of elevation as it winds around and makes another switchback, then heads NW to the trailhead. From the trailhead, the "trail" drops down to cross over the South Fork again. At the same TH, an ATV track continues NW above the creek. Both will eventually get you into the basin SE of Bennett.
There are two National Forest campgrounds on the drive to the end of CR/Fr 28 as mentioned above. While several other roads that turn off from FR 28 could take you to a possible primitive camp location, we recommend using either of the two NF campsites because there is a lot of cattle grazing in this area and private land. Please respect private property.
