The Tram is a popular destination for tourists, locals and people just looking to try something fun. The lower tram terminal is at the intersection of South Moody Avenue & Gibbs Street --the most transportation-diverse intersection in the country. Besides one of the nation's only aerial commuter trams, you'll see cars, buses, a streetcar, a soaring pedestrian bridge, a cycle track and the densest bike parking in America's #1 biking city. Bike valet is offered free to the public at Portland Aerial Tram Monday through Friday. Exiting the upper terminal you'll see the largest enclosed sky bridge in North America. Take a right to access an outdoor patio with seating and views of the terminal, the cityscape, the Willamette River and, on a clear day, Mount Hood and Mount St Helens. The upper terminal links to the 4T Trail--a self-guided tour by train, trail, tram and trolley. Much of Marquam Hill is a natural area with several trails.
