The 3.3-mile Lewis Falls loop winds from Big Meadows to cascades in the mountains.
Wild berries attract much wildlife in the area.
Before your trek, stop at the Byrd Visitor Center for local maps and information on guided nature walks. A distinctly urban walk that meanders along the San Antonio River. The path was laid out by conservationists in 1939 after the city wanted to cover the river with concrete and use it for drainage runoffs. Now it's a mix of greenery, water, shops, hotels, and busy restaurants. A short detour leads to the Alamo.
