Barbara J. Mapp Aviary Education Center

There’s a new destination at Radnor Lake and it’s really for the birds. Constructed as a boardwalk, nestled in the natural area, the wheelchair accessible facility provides educational programs, allows up-close observation of non-releasable birds of prey, and offers a bird’s eye view of the surrounding hillside and wildlife. In addition, interpretive displays on venomous snakes, non-venomous snakes and turtles are available inside the main building. The nearby amphitheater provides outdoor seating for our ranger-led educational programs.

To minimize stress on the captive birds at the aviary, initial public hours are limited to a two-day-a-week schedule. In addition, pets are not permitted on the boardwalk at the Barbara J. Mapp Aviary Education Center. The aviary center opened on May 2nd, 2015 and is now open two days a week.

Radnor Lake is day-use only and is protected as a Class II Natural Area, so the trails are strictly used for hiking and wildlife observation. Trails are off limits to pets, jogging, and bicycles. Trails are open from 6:00 AM to Sunset - Daily.

From November – April, a diversity of wintering waterfowl or transients can be easily viewed from anywhere along Otter Creek Road. Diving ducks such as Ring-necked and Canvasback are best seen near the center to west side of the lake, while marsh ducks such as Gadwall and American Widgeon prefer the shallower east end and the Big Slough. Observation decks are located along Otter Creek Road and along the Lake Trail. During spring and fall migration, birding the oak-hickory woods is popular and easiest along Otter Creek Road, the dam, Lake Trail and old caretaker residence.
