Along here it receives several tributaries from the right — Buttermilk Falls Brook, with its eponymous waterfall near its mouth, High Falls Brook and Bear Hole Brook — most of them rising, like the Rondout itself, in the Slide Mountain Wilderness Area to the west. To the east is another Forest Preserve management unit, the Sundown Wild Forest. Some unnamed tributaries come from here. Because of the protected areas on both sides of the creek and the ease of public access, this area has become one of the Catskills' popular trout streams, and fly-fishermen can be seen here during the season.
