One of the best hiking/biking trails in the St Louis area. Let me just qualify about the biking part first. This is a great hiking trail for those of you who like to bike trails with rolling hills for exercise. This is not a causal scenic Katy trail ride, a fast paced, paved Creve Coeur Lake Park ride, nor a Castlewood Park/Chubb Trail kind of ride. Rather, the trails here are enough to give you a good workout without you having to focus all your attention focusing on keeping to a singletrack type trail. Hiking wise - it is great as you get to see a variety of people and animals along the way. Queeny Park is also great for picnics with many open picnic areas around. It's a great park to just lay down a blanket to lie on and dream the day away. Like fishing, tennis, swimming, volleyball, Frisbee, kite-flying? Like bird watching? Seeing trees over a hundred years old? These are just some of the activities people do at the park. Just watch out for the horse dung piles along the trails.
