North Austin is an expansive area of oak-shaded residential neighborhoods, with a hopping zone of dining and nightlife. Along Burnet Road, modern eateries serve Asian-fusion to tacos, some in funky, retrofitted spaces, while Rock Rose Avenue thrums with bars and live music, and brewpubs dot the area. North Austin stretches from 2222 and continues north to Round Rock and Pflugerville. Shoppers hit the Domain and Arboretum malls, and hikers explore 15 miles of trails at rugged Walnut Creek Park. The influx of high-tech employers such as National Instruments, IBM, Motorola, and Freescale has led to huge growth in this area.
