Merkle Wildlife Sanctuary is the only wildlife sanctuary operated by the Maryland Department of Natural Resources. It is the wintering ground for several thousand Canada geese, the largest concentration on the western shore of the Chesapeake Bay. The 4.3 mile Chesapeake Bay Critical Area Driving Tour (CADT) is open for self-guided driving tours on Sundays from 10 a.m.-3 p.m. throughout the year. The CADT is open for hiking, biking, and horseback riding daily January 1st September 30th. The Frank Oslislo Visitors Center (open weekends, 10am to 4pm) overlooks several ponds, fields and woods sloping down to the Patuxent River. Its two-story wall of windows and circular balconies face a spectacular view. Inside you will find exhibits about the life history and management of the Canada Goose along with seasonal displays that encompass a variety of different environmental and wildlife topics, many of them kid friendly. Children will also love our live animal exhibit in our discovery room, with turtles, snakes, and toads. For those who love bird watching, there is a large bird feeder viewing area, stocked with binoculars and scopes that provide many hours of enjoyment.
