Each of these Pennsylvania natural wonders offers a glimpse into the natural beauty that's hidden throughout our beloved state.

1. Erie Bluffs – Erie

At a cozy 587 acres, Erie Bluffs State Park boasts quite a bit of natural beauty - one mile of unspoiled shoreline and forest wetlands, for example. (Swimming is not allowed at the park.) The highlight of the park, however, is its 90-foot bluffs that offer sweeping views of Lake Erie and the lush green of the park. Go on a hike that leads to sensational views at one of the 10 best natural wonders in PA. Learn more on the official website of Erie Bluffs State Park.

2. White Cliffs of Conoy – Marietta

The natural masterpiece of Koser Park is undoubtedly the White Cliffs of Conoy. Created by the dumping of limestone and dolomite waste, the White Cliffs of Conoy overlook the Susquehanna River and conjure images of the White Cliffs of Dover in England. Visitors are permitted to explore, and you'll take a 1.5-mile path to reach this natural wonder. However, be careful as the cliffs stand 60 feet above the river and can be dangerous. Read more about the White Cliffs of Conoy, a truly breathtaking PA natural wonder.

3. Hammersley Wild Area – Austin

Hammersley Wild Area has earned the distinction of being the most remote place in Pennsylvania. Offering tranquility and an abundance of natural beauty, the wild area is a must-add to any bucket list. The wild area spans more than 30,000 acres, and motorized vehicles are not allowed. You can, however, explore its trails on foot. Make sure you let someone know you'll be exploring this remote spot in Pennsylvania, as cell service tends to be spotty at best. Bring plenty of water and snacks, too. Here's the official website of Hammersley Wild Area.

4. Laurel Caverns – Farmington

Laurel Caverns is the deepest cave in Pennsylvania with a depth of 464 feet. However, visitors on the guided tour usually go down just 150 feet. In addition to guided tours, you can go spelunking and caving. The caverns are a seasonal attraction, closing in the winter months to allow the resident bats to hibernate. This is just one of the natural wonders in Pennsylvania the whole family will love. Check out the official website of Laurel Caverns for more information.

5. Bilger’s Rocks – Grampian

At more than 300 million years old, Bilger's Rocks is truly a natural wonder in PA and well worth a spot on your bucket list. The geological formations feature a series of caves, cliffs, passageways, and boulders. You can even climb the boulders. If you plan to spend the day, bring a picnic along, and go mountain biking after you've explored Bilger's Rocks. You can even spend the night at the campground.

6. Coudersport Ice Mine – Coudersport

A strange natural phenomenon, Coudersport Ice Mine in Coudersport welcomes visitors seasonally. The small ice mine freezes over, typically from April through October, during the warmer months while disappearing in the colder months. That makes it a fun spring or summer day trip destination. Find more information, including opening day and hours, on the official Facebook page of Coudersport Ice Mine.

7. Seven Tubs Recreation Area – Wilkes-Barre

Editor's Note: Seven Tubs Recreation Area is temporarily closed for improvements.

Tucked on 500 acres in Wilkes-Barre, Seven Tubs Recreation Area boasts a series of natural tubs (created from old potholes), small waterfalls, and pretty scenery. It's an ideal destination if you want to spend a bit of time in nature. Unfortunately, swimming is not allowed in the nature area. (If you like fairy homes, you're in for a surprise, too.) Read more about Seven Tubs Recreation Area, a unique Pennsylvania natural wonder.

8. Meadow Run Natural Waterslides – Ohiopyle

For a truly unique experience in the summer, glide down the Meadow Run Natural Waterslides at Ohiopyle State Park. The waterslides offer the perfect spot to cool off, although you might get a few bumps and bruises since you're sliding down a slide made out of 300-million-year-old sandstone. Bring a picnic along and, if you're up for an adventure, check out nearby Cucumber Falls and Ohiopyle Falls, just two of the waterfalls at this Western Pennsylvania state park. Find more information on the official website of Ohiopyle State Park.

9. Falls Trail – Ricketts Glen State Park

Most nature lovers love waterfalls. If you're a fan of waterfalls, you will absolutely love Ricketts Glen State Park. For a bit of a challenge, follow the Falls Trail, an epic waterfall trail in Pennsylvania. While it's considered between moderate and hard, the trail leads to all 22 of the park's waterfalls, making it a true Pennsylvania natural wonder. The tallest, Ganoga Falls, drops down 94 feet. Head over to the official website of Ricketts Glen State Park.

10. Archbald Pothole – Archbald

Those of us who live in PA know a whole lot about potholes. After all, we tend to run into them quite a bit of the time when we're driving. For the largest pothole in Pennsylvania, make your way to Archbald Pothole State Park. It's home to the Archbald Pothole, which measures 42 feet by 24 feet at its widest point and boasts a depth of 38 feet. If that's hard to imagine, you could fit 35 firetrucks into the pothole. It's definitely a unique natural wonder in Pennsylvania that's well worth a visit. Check out the official website of Archbald State Park.
