Interpretive Programs and Events

Barbara J. Mapp Aviary Education Center 

The Barbara J. Mapp Aviary Education Center will open in Spring 2015. The aviary will house several birds of prey ranging from great horned owls to bald eagles. This 550 foot boardwalk and aviary complex will become the epicenter of the birds of prey programming for the ranger staff and offer park visitors a unique opportunity unparalleled in Middle Tennessee.

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. Thanks to recent $50,000 matching grant from Barbara J. Mapp Foundation and many generous donors, phase one is nearing completion and permitting to place birds in the pens has been submitted. The permitting can take up to 90 days. We hope to have raptors in their new homes by December 2014.
  • 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. 
Canoe Floats

Between Memorial Day and Labor Day, the ranger staff at Radnor Lake offer interpretive canoe floats 3-4 times weekly. These floats are approximately 1-2 hours in length, require registration and are offered at no cost to park visitors. Paddles, life jackets and canoes are provided by the park staff for park visitors. No private boats are permitted at anytime. Canoe Floats are not offered between Labor Day and Memorial Day due to waterfowl migration and/or impact upon wildlife observation.   

Scheduled floats will vary in time of day and days of the week to ensure we offer this experience for all of our park visitors. However, most floats during the summer months are at sunrise and sunset hours due to heat and increased wildlife viewing opportunities for visitors on the floats. Rangers leading the float will stop periodically to view wildlife, discuss the history of the lake and/or to discuss land acquisition projects occurring with Friends of Radnor Lake. 

For more information on canoe floats at Radnor Lake, please see our monthly program schedule beginning on Memorial Day Weekend thru Labor Day Weekend. 


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.
