Penn Park, the rejuvenated 24-acre strip of land along the train tracks between Walnut and South streets, officially opens on Thursday.

The park occupies former parking lots and vacant land in a once fairly desolate area that was a parking area for postal trucks. It is now part of the University of Pennsylvania campus.

So what can your typical West Philly resident get out of the new park? Some of its facilities will be open to the public on a regular basis. Those include about two acres of grassy open areas, including a “picnic grove,” with a good view of the Center City skyline in and around newly constructed athletic facilities. The area also includes 548 new trees.

“Penn Park marks the first time that the University has, by design, developed open space for the use of the Penn community and beyond,” said Penn President Amy Gutmann.

Those athletics facilities include a spiffy 12-court tennis center, a 470-seat multi-purpose stadium and two athletic fields with synthetic surfaces. A parking lot for 210 cars sits along Walnut Street near the Class of 1923 Ice Rink. In case you had any notion of getting your Nadal on and playing tennis on those new courts (we did), Penn has said that they will only be open to the public on special occasions.

Still, the park provides a nice place to relax, enjoy the skyline and maybe take in a field hockey game.

The park is accessible by Walnut Street to the north, a walkway near the picnic grove to the west and another entrance near the South Street bridge. Here is a map of the park: Penn Park map

The park cost $46 million, but not a dime of public money went into it, according to Penn officials.

Tomorrow’s ceremony begins at 5 p.m. and will include a ribbon-cutting, recreational activities and a fireworks display at 7:30 p.m.
