Public transit often produces a lackluster ride, with trains plodding through rush-hour traffic or bus drivers prohibiting recreational use of their vehicle’s ejector seats. Renounce earthbound commutes with today's Groupon: for $4, you get a roundtrip ride for two from Portland Aerial Tram (an $8 value).

One of two aerial tramways designed for public transit in North America, the Portland Aerial Tram ferries riders across the skies between Marquam Hill and Oregon Health and Science University's Center for Health and Healing at South Waterfront. After a 500-foot vertical ascent, riders bask in the panoramic views of the skyline and Cascade Mountains during their trip over I-5, Lair Hill, and the city’s ongoing joust tournament. Hop off at OHSU and indulge in a helping of soft-serve Dreyers ice cream at the main dining room (not included with this Groupon) for a sweet treat between trips, or simply revel in the sights from the sculpture garden or observation desk.
