One of our favorite local spots to go is Hawk Mountain in Kempton Pennsylvania. They do have a fee for entry which ranges from $5.00 for children, up to $9.00 for adults. Senior citizens get a discounted rate of $7.00 and children under 5 are free. You can also become a member for fees ranging from $40.00 to $250.00 depending on what your needs are. The trails are open from dusk to dawn. They do not allow dogs on the trails, so that is a downside for us. If you are into bird watching/spotting, this is the place for you! They have a log of how many Raptors are spotted each day. There are six different trails ranging in difficulty from easy, to moderate, to difficult, with the longest trail being four miles long. They have awesome rock climbing spots and amazing views everywhere you go. It is always a good time when we visit Hawk Mountain!
