Yellow Creek State Park, Pennsylvania

Everything revolves around Yellow Creek Lake at Yellow Creek State Park. Eighteen miles of mountain bike trails loop around the 720-acre lake and while multiple fishing spots dot the perimeter. For those towing a lighter load, eat a meal al fresco after a long day of swimming and while oohing and aahing over the sunset.

For all you wannabe biologists out there, grab the mini-notebook and head down the two-mile Ridgetop Trail. Start at the beach and wander through a variety of wildlife habitats taking notes along the way–macro-lense camera also recommended. Walk on the willdside during the winter months with rogue snowshoeing and skiing when the only blazing trail is your own two feet.
