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.
