If you are new to Austin or planning to visit Austin with a bicycle there are two paths that you should check out.
The best bicycle route in Austin is the Veloway which is a 3 mile circular loop through Slaughter Creek Metropolitan Park. It is open from dawn to dusk except on very select days. The Veloway is open to only bicyclists. Other facilities in the park include a huge soccer complex, a basketball court, volleyball court, picnic area, disc golf course, hiking paths and play equipment.
For those who prefer not to ride on a closed circular loop path then try the Barton Creek Greenbelt. The trail which is approximately 7 miles in length incorporates many different kinds of terrain. The main starting point for the trail is Zilker Park. The original land for the park was given to the city in 1918 and was added to during World War I. The trail continues to the Hill of Life. Bikers are encouraged to park in the lot near the swimming pool which will cost you 2.00. Then follow the trial along the river. Stay as close to the river as possible since hikers tend to stay on the trails further away from the river.
These two options are very unique riding opportunities in Austin, Texas.
