The Rio Grande flows in front of you, from right to left, heading for a curve in the limestone bluff. The sandy floodplain around you is home to tail-dragging lizards, long-eared jackrabbits, raccoons, and other animals. Take some time to explore the river and its surroundings. Listen for bird song and the splashes of turtles entering the water. Peer into the river and search for fish. Close your eyes and feel the wind against your skin, the warmth of the sun, and notice the lack of loud noises. Many people say one of the things that impresses them the most about Big Bend is the silence. What do you hear at this location?
