Summer is here, and it's time to start planning which Pennsylvania swimming holes you'll head to in order to stay cool all season long. After all, you can only go to the community pool so many times before its rectangular regularity gets a bit... bland. If you've been asking yourself about the best swimming holes in PA, look no further! Here are some of the best naturally occurring or at least, lake-ish, swimming holes in Pennsylvania.

1. Meadow Run Natural Waterslide, Ohiopyle State Park

If you're up for a bit of hiking and swimming (or gliding, in this case), you can't go wrong with the natural waterslide at Ohiopyle State Park. Follow the Meadow Run Trail that leads to two waterfalls and this natural waterslide. However, before you go down the waterslide, be prepared to get a few bumps and bruises since you're sliding on sandstone that's millions of years old. The natural waterslide can get incredibly busy, especially on hot summer days, and there are no lifeguards on duty. Plan your journey down this natural waterslide in Pennsylvania.

2. Perkiomen Creek, Philadelphia

Looking for a beloved swimming hole in PA? Take a dip in this refreshing creek that runs to the southeast of Philadelphia. Be careful on the water, as there are obviously no lifeguards. The creek is also popular with outdoor adventurers on kayaks and on canoes.

3. Raccoon Creek State Park, Hookstown

The swimming area at Raccoon Creek State Park offers a refreshing oasis from the summer heat. Spend the day lounging on the sand of the 500-foot beach or wade in Raccoon Lake to cool off. The beach also features a concession stand and a bathhouse. Get a peek at this gorgeous Pennsylvania swimming hole.

4. Lake Erie

DUH! Of course you should check out the biggest and most impressive body of water that our state has to offer. In fact, you'll find yourself spoiled with choices at Lake Erie, which boasts 11 pristine sandy beaches. Head to Presque Isle State Park, where you can choose one of the beaches, on which to lounge, that leads straight into the blue water of Lake Erie.

5. Salt Springs State Park Montrose, PA

With many trails, overnight camping, and three waterfalls to visit, this state park has more than enough activities to fill a summer day and night. While you won't find an official swimming hole at the park, you can dip your feet in the cool water of the waterfall at Salt Springs State Park.

6. Lackawaxen River, Masthope

Flowing through the Poconos, the Lackawaxen is the perfect place to kick back with some friends and take a dip. If you prefer spending time on the water instead of in the water, consider a day of kayaking down the river. Fishing is also popular at the Lackawaxen River.

7. Black Moshannon State Park, Centre County

This beach looks like something straight out of a dream, making it one of the best swimming holes in PA. Find the perfect spot on the sand or on the grass to drop your beach towel or your beach chair. Soak up the sun before heading into the cool lake water. There are no lifeguards at the beach at Black Moshannon State Park, so it's swim at your own risk.

8. Rock Run, Williamsport

Rock Run has been named one of the best watering holes in the United States, and after you watch this video, we bet you'll agree.
