You know all about the seven wonders of the world, but you might be less familiar with wonders in our own backyard. From ancient plants, to musical boulders, massive viaducts, and more — read on to find out the most amazing wonders of the world in Pennsylvania.

1. The Hoverter and Sholl Box Huckleberry Natural Area

This is one of the lesser-known (but unbelievably cool) things about Pennsylvania. One of the world's oldest living organisms can be found in Perry County - two separate colonies of box huckleberry. The specimen located within the protected area is estimated to be at least 1,300 years old, while a colony located in the nearby Losh Run is estimated to be at least 13,000 years old. Unfortunately, most of the older colony was destroyed due to road work in the 1970s and is not marked for visitors. When you think ancient organisms, you might think sequoia trees, towering pine trees, or bizarre sea sponges hidden in the depths of the ocean— usually not an innocuous bush that you might pass in the Pennsylvania woods without noticing. Learn more on the official website of Tuscarora State Forest.
2. Ringing Rocks County Park

Get your hammer, bring your friends...this is one of the weirdest experiences you're likely to have in nature. Due to a unique chemical composition, an unusual phenomenon occurs at Ringing Rocks County Park; as you might expect from its name, the boulders emit a ringing sound when you strike them. Stop by the website of Ringing Rocks County Park.
3. Kinzua Bridge

When it was first built in 1882, the Kinzua Viaduct was heralded as the eighth wonder of the world. It was at the time the tallest railroad bridge in the world. In 2003, a tornado caused a large portion of the bridge to collapse, and today it is a popular attraction, having been transformed into a striking display of human artifice and also nature's reclaiming powers; the bridge's fallen structures were left in the valley below as a testimony to what once stood there. You can even walk down the remainder of the bridge - the Kinzua Bridge Skywalk - which features a glass floor. Stop by the official website of Kinzua Bridge State Park.
4. Austin Dam

Similar to the Kinzua Bridge, Austin Dam is another reminder of the fallibility of human architecture. Due to issues in its construction, the dam only held for 11 years before bursting; a paper mill and most of the town of Austin was destroyed in the devastating accident.

There are a few caves in Pennsylvania that you can visit, but Penn's Cave is by far the most distinctive thanks to its limestone structures and its unique subterranean rivers. You will enter the cave by boat and travel deep into the 1,300-foot cavern. Check out the official website of Penn's Cave.
6. Tunkhannock Viaduct

When the Tunkhannock Creek Viaduct was completed, it was the largest concrete structure in the world, and held the title of the largest concrete bridge in America for at least 50 years after the fact. Though it is certainly gigantic to the naked eye, the majority of its mass is located underground. Find more information on the Tunkhannock Creek Viaduct.
7. Bushkill Falls

Bushkill Falls is colloquially known as the "Niagara of Pennsylvania" thanks to its impressive array of giant, beautiful waterfalls. It requires an admission fee, but the ticket is worth the experience. There are few other spots like Bushkill Falls anywhere in the eastern part of the country. Head over to the official website of Bushkill Falls.

What is the most scenic town in Pennsylvania?

Tionesta is one of the most scenic towns in Pennsylvania and more than worthy of a spot on any bucket list. The tiny town is home to just around 500 residents and is dotted with charming storefronts and homes. If you love being outdoors, spend time on Tionesta Lake. Although not technically a town, Eagle’s Mere is a simply adorable village where you’ll find some cool Pennsylvania attractions. It’s within easy driving distance of Worlds End State Park and features a toboggan ride right through town during the winter (weather-permitting).

What are the most well-known parks in Pennsylvania?

Pennsylvania lays claim to 121 state parks, and some of them are more well-known than others. If you’re looking for things to see in Pennsylvania, you’ll definitely want to add Leonard Harrison State Park and Colton Point State Park to your itinerary. Both offer sensational views of Pine Creek Gorge (The Grand Canyon of PA). Kinzua Bridge State Park is home to the remnants of Kinzua Bridge, which now features a gorgeous skywalk with a glass floor. If you’re up for a bit of stargazing, you’ll find some of the darkest skies on the Eastern Seaboard at Cherry Springs State Park.

What are the most well-known waterfalls in Pennsylvania?

One of the prettiest things to see in Pennsylvania is, arguably, the waterfalls that dot the state. While Ricketts Glen State Park boasts the most waterfalls with 21 and you can see them along one trail, there are an abundance of other beautiful waterfalls in Pennsylvania, too. Bushkill Falls, for example, features eight waterfalls along a two-mile path. If you’re on the western side of the state, make your way to Ohiopyle State Park, home to Ohiopyle Falls, Cucumber Falls, and Johnathan Run Falls. Both Ohiopyle Falls and Cucumbers Falls are viewable without heading out on a hike.
