Spring and summer visits promise opportunity to see many oscines, as this area continues to deserve its reputation as one of the best places in the state to find nesting warblers. These include, Blue-winged, Prothonotary, Worm-eating, Yellow, Yellow-throated and Black-and-white Warblers, Northern Parula, Louisiana Waterthrush and Common Yellowthroat. Also present are Warbling, White-eyed and Red-eyed Vireos and Summer Tanager, Eastern Wood-Peewee, Eastern Phoebe and Eastern Kingbird.

3 parking areas (1 gravel, 1 small roadside grass area, 1 at campground). The small grass parking area is adjacent to the fen natural area. There are two Natural Areas. 40-acre Big Buffalo Fen, on the north side of the road, includes a deep muck fen, a sedge meadow shrub fen and a wet meadow. The 5-acre mesic bottomland Big Buffalo Creek Forest Natural Area is in the Morgan County portion, on the south side of the road, just as it enters the area at the southeast corner. 

Easy viewing of bottomland along Pole Hollow Creek and Heron Pond is possible from the road and from the two larger parking areas and campground.

Big Buffalo Lake (a 5-acre pond) may have waterfowl from fall to early spring, but is a mile from the nearest parking lot.

The 4.5 miles of multi-use trails are the only access to much of the area. Most of it (1,477 acres) is in forest or woodland.
