Trough Creek State Park – Where rugged cliffs, creeks and waterfalls shape a wild landscape
When I was on my journey of running one mile in all-then 121 Pennsylvania state parks in 2021, I took notes after every run. It was an effort to make sure I would remember my experiences. I’d take notes like, I spotted a fox here. Or I fell there. Or I want to hike the full trail here. But one of the most important pieces of information I recorded was my overall feeling of the park. It’s difficult to get a sense of a natural landscape in just one mile, often running half a mile one way ...

Pymatuning State Park - Explore the largest lake in Pennsylvania, where ducks walk on the backs of fish
Pymatuning State Park is big in every sense of the word. It is the largest state park in Pennsylvania. Its Pymatuning Reservoir is the largest lake in Pennsylvania. And it’s one of the most visited state parks with more than three and a half million visitors a year. But just because it has these big qualities does not mean you’ll be unable to find your own peaceful spot at Pymatuning. For every space taken up by a family BBQing, there are nooks and crannies that allow you to explore the park ...

Celebrating Pennsylvania's historic place in America's 250th birthday
The story of the United States of America cannot be told without Pennsylvania. Independence Hall. The Declaration of Independence. Philadelphia. The Liberty Bell. Benjamin Franklin. George Washington’s Crossing of the Delaware. The Battle of Brandywine. And Valley Forge. Pennsylvania is called the Keystone State because it refers to the central stone in an arch that holds all other stones in place, symbolizing strength and stability. Pennsylvania was the hub of political and economic ac...

Exploring ancient rock carvings in the Susquehanna River with Paul Nevin
Hundreds of years ago, a group of Native Americans living along the lower Susquehanna River made an indelible mark on the valley. At what is now known as Safe Harbor, they made hundreds of carvings into the rocks found in the middle of the river. Animals, bird and animal tracks, directional symbols, teaching or storytelling images, humans and anthropomorphic images, spiritual symbols and geometric and abstract designs were painstakingly carved into the boulder strewn landscape of the river. F...

Feeling posh? Try one of Pennsylvania's new state park glamping sites
For a long time, there’s been this mostly unspoken rule that “real” outdoor experiences have to be rugged. You’ve got to rough it, hike ten miles in the rain, sleep on the ground and eat beans from a can — or else it somehow doesn’t count. Luckily, that’s changing. More and more people are discovering that you don’t have to give up comfort to connect with the outdoors. Here in Pennsylvania – especially in state parks - that change has been evident. Instead of only offering tent sites, s...

Nolde Forest Environmental Education Center - How one tree led to a thriving outdoor classroom
In Pennsylvania, every state park has its purpose. Allegheny Islands shows people what undeveloped islands once looked like on the river. Colton Point features stunning views of the Pennsylvania Grand Canyon. And Pine Grove Furnace highlights the iron making industry crucial to Pennsylvania and America’s growth. But are there any places set aside for learning and study. As it turns out, there is. One such place is Nolde Forest Environmental Education Center. Located in Berks County, Nolde For...

Under the surface of the Keystone State with geologist Russell Losco
One of the strangest things about getting older has been the shift in my interests. Despite being intensely curious as a kid, I never cared about nature growing up. I didn’t climb trees or capture bugs or explore creeks. But as I’ve gotten older all that’s changed. Which has made me feel like I’m constantly catching up to those that spent their early lives trekking through the woods, paddling on rivers and exploring the natural world. I often think to myself, “Am I too old to star...

Salt Springs State Park - Explore ancient hemlocks, waterfalls and wildflowers in NEPA
What is it that makes a state park special? It’s a question I’ve asked my self countless times since I began exploring Pennsylvania’s public lands in 2021. For some it’s deep, meaningful history to indigenous cultures, to early settlers or even to industry. For others its beautiful features like waterfalls, old growth forests and scenic vistas. And for many it’s the landscapes that allow them to hike, bike, paddle, birdwatch, hunt, fish and more. For me, I’ve found that parks I deem spe...

Uncovering the battles that scarred Pennsylvania's public lands with author Brady J. Crytzer
When people think about history, especially armed conflicts, many picture dusty textbooks, old maps and long-forgotten generals. But here in Pennsylvania, history isn’t just words on a page—it’s written into the very ground beneath our feet. From the rolling hills of Gettysburg, where the fate of a nation turned in just three days, to the banks of the Brandywine, where the Revolutionary War nearly lost its footing, to the quiet frontier where settlers clashed in the Whiskey Rebellion—Pennsylv...
