If you don't venture north of LBJ Freeway often, Plano and natural beauty might not seem to go together all that well. Judging from the often crowded parking lot at Arbor Hills Nature Preserve, however, more people continue to see the correlation. With over 200 acres in West Plano, the preserve offers surprisingly hilly options for hikers and bikers with paved and off-road trails. The preserve's observation tower affords a gorgeously sweeping panoramic view into the suburban distance.
