Destination guide
Austin: Live music, barbecue and Hill Country swimming holes
Austin's airport has more than tripled its routes in a decade, with nonstops from both coasts and Europe. The draw is the live-music scene, world-famous barbecue, Barton Springs and the Hill Country just beyond the city limits.
Best time to visit: March–May and October–November are warm without the brutal summer heat. Avoid SXSW (mid-March) and ACL (October weekends) unless you're attending — fares and hotels double.
