One of Pennsylvania's most popular recreation areas, the Poconos comprise a section of low-lying mountains that sprawl across the state's Northeast. Bounded by the Lehigh and Delaware Rivers, this accessible area delights with its many lake retreats, charming small towns, and forested terrain (as well as its proximity to Philadelphia and New York City). There are things to do in the Pocono Mountains all year round—in the summer, hiking, mountain biking, and fishing reign, while in the winter, ski resorts like Camelback make it easy to hit the slopes.
