Radnor Lake State Park

Barbara J. Mapp Aviary Education Center

7:00 AM to 1:00 PM - Wednesdays 
1:00 PM to Sunset - Saturdays 

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.


The Barbara J. Mapp Aviary Education Center is located at the top of Hall Drive, off of Otter Creek Rd.

From West Parking Area (Walter Criley Visitor Center), walk east on Otter Creek Road to Hall Drive to Aviary is 1.4 miles. The hike up to Hall Drive is paved but steep.

Aviary Project Update

The Barbara J. Mapp Aviary Education Center project consists of two phases.

  • Phase I – 550 foot boardwalk and five pens that will be home to four non-flighted raptors and one non-flighted American Bald Eagle. Phase I is complete thanks to a recent $50,000 matching grant from Barbara J. Mapp Foundation and many generous donors.
  • Phase II – a netted Eagle aviary that will house two flighted American Bald Eagles. Friends of Radnor Lake is actively fundraising by seeking grants, corporate partners and private donations to raise the final $100,000 to complete the Eagle Aviary, and related education programs and materials.
