Radnor Lake State Park


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. 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. 

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.
