This one is a little out of the way, but it’s perfect if you're picking up your visitors from the airport and want to make a pit stop. John Heinz is the nation's first urban refuge and it features plenty of flat trails and opportunities for bird watching. Best of all, it's free.

It's easy to spend an entire day at Penn's Museum of Archeology and Anthropology, where there are, roughly, one million artifacts on display or being tended to on a daily basis. Bonus: You can buy a double ticket here, which also offers admission to the creepy but cool Mutter Museum.

You don't have to try hard to get a great view of Philly. Take your folks up to the free Cira Green, a beautiful park on top of a parking garage in University City. You'll see views of the Schuylkill River and Center City, plus down to the art museum and back toward West Philly.

The PAFA boasts what is undoubtedly one of the most stunning interiors in the city. The historic landmark building, designed by Frank Furness, features an array of exhibits.

This historic museum dates back to 1855, when it began providing free education classes on science to Philly residents. Today, it remains relatively untouched and features a museum in a gorgeous 3-story space with natural artifacts gathered mostly by William Wagner himself.

We know: A hospital is probably the last place you'd want to visit with your family. But consider this: It's steeped in history, given that it's the first hospital in the nation. Plus: It boasts the first surgical operating theater—yes, theater—in the country. It's a beautiful space to boot.

If you want to avoid the shopping crowds on Chestnut Street, take your visitors to Queen Village's Fabric Row, where, as our friends at Racked put it, "you can find some of best vintage shopping on the East Coast." There are indie shops and boutiques, cute cafes, and it's a short walk to the popular South Street.

Welcome to the smallest national park in the country. Kosciuszko was a good friend of Thomas Jefferson, who he entertained numerous times in this small brick corner home in Old City. It's one of the least visited parks in the U.S., so show it some love and take a tour.

This vibrant and open pier is a new addition to the Old City landscape, and one that’s definitely worth checking out, especially if you’re planning more tourist-y stops in the area. It opened last year after a long renovation process, and offers vendors, an outdoor garden, and 14 artists working on site. Stop by and watch them go, buy a painting, grab a bite, and look out over the killer views of the Delaware and Ben Franklin Bridge.

Tucked away on 4th and Pine, in the heart of the historic part of Philly, it’s a surprise this cemetery isn’t a more popular spot to visit. Many of the graves date back hundreds of years, and plenty of Revolutionary War soldiers are buried here. Take time to read the plaques at the graves; there are tons of fascinating stories.
