Park at N30*14.122 W097*49.243 to enjoy this fun and quiet backdoor entrance to Austin's greenbelt system. Trailhead is approximately .07 miles north of the parking waypoint.
Or, if you're of hardy stock and febile wit, cache in from the 360 trailhead and make this cache a 2fer with the Greenbelt and Beyond Cache on the same little side trail.
Or, if you're really, really buff (and perhaps all of those steroids you've been taking have destroyed a just a few too many neurons) keep right on following the trail under Mopac and beyond to the caches in the Travis Country area.
WHEW!!! Cache on!!
