As the name implies, the Genesee Valley Wildlife Management Area is located within the valley of the Genesee River. Two noncontiguous parcels comprise this 717-acre property, most of which is along the east side of the river. The terrain consists of low-lying wetlands and flatlands along the river and low, rolling hills to the east of the river.

A variety of habitats are found here, including wetlands, meadows, cornfields, woodlands, and open waters. These diverse habitats support a wide variety of wildlife species: Species such as beaver, muskrat, mink, and raccoon are associated with wet and riverine habitats; fox, squirrel, rabbit, and white-tailed deer are more associated with upland habitats; and a huge variety of song birds, raptors, and waterfowl, as well as grouse, woodcock, and turkey can be found throughout this property. Also present are many species of grasses, flowering plants, and trees, most of which are wild, but some of which are descended from species planted when this property was inhabited by people.

Activities allowed on this property include birding, canoeing and kayaking, fishing, hiking, hunting and trapping, and nature viewing. For regulations regarding the use of wildlife management areas, see Links.

Birding

Because of the diverse habitats found here, this wildlife management area provides opportunities to spot a wide variety of birds, including shorebirds, song birds, raptors, and waterfowl, as well as grouse, woodcock, and turkey. See Links for a list of bird species seen in this WMA.

Camping

Camping is not allowed in this WMA.

Fishing

Fishing opportunities in this WMA are provided by the Genesee River. This section of the river provides good fishing for smallmouth bass in the summer and fall. Carp, suckers, and small populations of yellow perch and bullhead are also found in this section of the river.

Hunting and Trapping

This wildlife management area provides opportunities for both small game and big game hunting. Game species commonly found here include white-tailed deer, turkey, and waterfowl. Hunting and trapping are permitted on the property in accordance with all game regulations, unless otherwise posted.

Trails

There are no formal trails in this WMA. Access to the interior is provided by local roads and a DEC administrative road (vehicle access is prohibited), which can be used for hiking, snowshoeing, and cross-country skiing. The use of motorized vehicles, including snowmobiles and ATVs, is not allowed in this WMA.

I couldn't find any specific information regarding horseback riding here, but this doesn't seem like a good place to take a horse, and the DEC generally prefers that horseback riding be enjoyed only on trails designated for such use. 

It should be noted that several of the roads in this area are not well identified on some maps. To get to the DEC gate near the Genesee River, bear to the left onto South River Road from Mudville Road after passing westward under the old railroad grade. And unlike what is shown on some maps, South River Road and Otis Smith Road no longer connect because the river has washed out the road. The DEC has indicated that a new connection between the two roads might be constructed in the future; this connection would be constructed further inland from the river.  (The map pin is located on the end of South River Road. Google sometimes misidentifies this as Mudville Road.)
