With heavy rains, we couldn’t explore much, but we did walk down the the Lehigh River. It is a 32-mile gorge with raft rides and bike paths. You can put your bike on a train and then ride back to the town, Jim Thorpe, a 25-mile trip with a slight down hill train slope. You can also kayak or canoe it, but it is not for amateurs. A lot depends on how much water is released from the dam. There are a number of free shuttles to carry bikers to towns for lunch or exploring.
The Lehigh River flows for over 100 miles and is the largest tributary to the Delaware River. According to dryflyfishing.com there is a healthy population of brown and rainbow trout. There are also smallmouth bass “that fight like hell.”
Between the Delaware River and the Lehigh River and Hickory Run State Park, this area has a lot to offer. I’m sure it gets busy in the summer.
