There are lots of ways to tour Philadelphia. In fact, there are several walking ghost tours of the city, but here's one tour you may not be aware of:

Philly From the Top is offering twilight tours from the 57th floor of One Liberty Observation Deck.

The tour's website promises that during the 30-minute tour, visitors will "learn about where to ghost hunt or where to avoid during All Hallows' Eve."

Tours happen Fridays and Saturdays at 5 pm & 6 pm through Oct. 28th (and on Halloween).

The tour is free with the purchase of an admission ticket to the observation deck and no reservations are needed.

Tickets are $14.50 for ages 12+ and $9.50 for ages 3-11.  (There is a 5% discount if you purchase tickets online).
