River Legacy Parks Paddling Trail offers a quiet Trinity River float through 1,300 acres of Arlington woods, wetlands, and wildlife habitat. Paddlers launch near the Collins Street entrance and choose a two- to eight-mile out-and-back trip depending on water flow, wind, and how far upstream they want to explore. Herons, turtles, kingfishers, and occasional riffles make the route feel surprisingly wild. Bring your own boat or arrange rentals and instruction through local outfitters.
