The new One Liberty Observation Deck, with its floor-to-ceiling windows and 360-degree views of Philadelphia, will join the Philadelphia CityPASS® program. Located on the 57th floor of One Liberty Place skyscraper, the observation deck soars 883 feet (269 m) above street level. From this vantage point, visitors can soak in views of the city that Lonely Planet, the largest travel guidebook publisher in the world, placed at the very top of its 2016 “Best in the U.S.” list of recommended travel sites.

Opened just three months ago, One Liberty Observation Deck features the latest in interactive technology. Visitors can get a closer look at key landmarks in and around Philadelphia by using one of the six “Go Find Your Philly” touch-screen monitors. Offering a high-definition look at noteworthy sites around the region, the monitors allow guests to instantly zoom in to get even more information on the given landmark's history and architecture. This is technology at its finest—and highest—point.

As of March 1, the start of the program year, each 2016 Philadelphia CityPASS ticket booklet will save travelers 45 percent off combined admission to the included attractions: The Franklin Institute, Big Bus Company and Philadelphia Trolley Works, One Liberty Observation Deck, and a choice between Adventure Aquarium or the Philadelphia Zoo.

Philadelphia CityPASS prices, starting March 1: $59 for adults (a value of $108); $39 for children, age 2-12. Ticket booklets can be purchased online at or at any of the participating attractions. Ticket booklets are valid for nine consecutive days, beginning with the first day of use.
