Portland's great transportation system and walkable streets make it easy and pleasant to get anywhere in town. Within the Free Rail Zone, a 330-block area in the central city, there's no charge for transportation aboard MAX light rail trains, trolleys, or streetcars. Riders lucky enough to catch the historic Vintage Trolley (Sundays only) along the MAX route are even treated to a guided tour. The Free Rail Zone also stretches across the Willamette River to include stops at the Rose Garden Arena (home to the Portland Trail Blazers), the Oregon Convention Center, and Lloyd Center Mall. There's also no sales tax in Oregon, which makes shopping that much more fun here!
