Ride the Duquesne or Monongahela Incline
Also known as funiculars, these "inclined planes" were built in the late 1800s to transport immigrant workers from work at plants along Pittsburgh's rivers to their homes atop Mt. Washington.
While they still serve as transportation for area residents, they are also a great way to enjoy the beautiful panoramic Pittsburgh skyline, a view ranked as the second most beautiful place in America by USA Today. The Duquesne Incline, still utilizing the two original 1877 wooden cable cars, is also a working museum.
Have Lunch at Primanti's
While you may not want to squeeze into a bikini after eating one of these world-famous sandwiches, but it's not a true trip to the Steel City without a stop at Primanti's.
These massive sandwiches are served with the meat of your choice and topped with up with coleslaw and French fries. Several locations exist around the city, but the original 1933 location in the heart of Pittsburgh's historic Strip district, open all day and night, is the best.
Can't Miss Point State Park
This tiny state park in downtown Pittsburgh is built on land once coveted by three empires, and where the Monongahela and Allegheny rivers meet to form the Ohio River.
It contains one of the tallest fountains in the nation (a 275-foot geyser that blasts 6,000 gallons of water per minute)is fed by an aquifer found 53 feet underground, which is sometimes referred to as Pittsburgh's fourth river.
While there, explore the Fort Pitt Block House museum located among the remains of the famous British fort or just sit and watch the boats go by.

Take in a Game
It's hard to think of Pittsburgh and not think about sports, and in the summertime, it's all about baseball. Get into Pittsburgh's strong steel spirit by cheering on their hometown heroes, the Pirates. Even if you're not a sports fan, a trip to PNC Park is still a must, as it one of the most beautiful ballparks in major league baseball.
Visit the Cathedral of Learning
Another great way to escape the summer swelter is visiting the 42-story neo-Gothic structure at the center of the University of Pittsburgh campus.
This enormous cathedral contains 26 Nationality Rooms designed by the different ethnic groups that resided in Allegheny County.
On the grounds of the site, you'll also find the beautiful Heinz Memorial Chapel which, with its 23 enormous stained-glass windows, is a favorite Pittsburgh wedding location.

There is also an impressive collection of classic rides, charming buildings, and old-fashioned fun.
Wander Through Allegheny Cemetery
One of the most picturesque places in Pittsburgh, Allegheny Cemetery is also unexpectedly romantic with 300 acres of rolling hills and beautiful monuments.
The cemetery houses gravesites dating back to the French and Indian war. Stop and get a map of the graves to pay your respects to some famous Pittsburghers including composer Stephen Collins Foster and America's first glamour girl, Lillian Russell.
