If you want an outdoor experience that feels truly majestic, head to Tioga County to witness the Pennsylvania Grand Canyon (officially the Pine Creek Gorge). Spanning 47 miles and dropping nearly 1,000 feet deep, it offers breathtaking overlooks and is flanked by the Pine Creek Rail Trail, widely considered one of the best biking trails in the country. Another must-visit is Ohiopyle State Park in the southwestern part of the state, famous for its intense whitewater rafting on the Youghiogheny River and its proximity to Frank Lloyd Wright's architectural masterpiece, Fallingwater.
