2 Best Sights in Austin, Texas

This 12-mile series of hike-and-bike trails follows the contour of Barton Creek and the canyon it created west along an 8-mile-long area from Zilker Park to west of Loop 360. The popular Greenbelt features even more sought-after swimming holes when the creek is full (very rain-dependent, it's usually in spring and fall). Several access points will get you on the riverside trails, including at Zilker Park, Loop 360, Twin Falls, Scottish Woods Trail Falls (near the intersection of MoPac and Loop 360), and Scottish Woods Trail (at the trail's northern border, off Loop 360).

This paved asphalt loop winds for a little more than 3 miles through Slaughter Creek Metropolitan Park and is reserved exclusively for bicyclists and rollerbladers. Riders always travel in a one-way clockwise direction. It's a bit off-the-beaten path, but not far from the Lady Bird Johnson Wildflower Center. There are no facilities other than a water fountain that sometimes doesn't work. The loop track is open every day, from dawn to dusk. No dogs are allowed.
