Starting at NF-512 road TH just north of Albert Pike, this 25.31 (some sources claim 28 miles but no) mile loop is best done in 2.5 days. In general, the entire west side is steep up and down, crossing six ridges, the most northern ridge having a view point with 4G service if needed. The northern section is really nice, winding around forest hills, totally under a tree canopy, hopping over streams. The east side is easy and flat, passing some old wagon trails, 4x4 trails, and small clearings where you'll see deer. The southeast corner has some rock beaches and large camping areas for groups. The south section tends to get more marshy in times of high rain, lots of down trees, but there is a swimming hole and rock ledges. There are numerous primitive sites around the entire loop, some of them fairly close to the river which should be avoided if rain is in the forecast. Guthook has this map and the campsites and crossings are fairly accurate, not all campsites shown of course. The major water crossings can be dangerous to cross if the gauge level is above 4.0, however I did cross West Baylock at nearly 8.0 on the LM gauge (water thigh-high) and the two northeast Little Missouri crossings with a gauge level about 5.25 with little difficulty using trekking poles and going a couple dozen yards upstream of the trail, away from the rapids. Water was nearly waist-deep. When I crossed the two crossings at the lower southeast end the gauge level was 4.25 and water thigh-high.
