Clark Reservation State Park is one of the older state parks in New York, has been continually in operation since the late 1940s. Initially covered in miles of ice in the distant past, Clark Reservation State Park is covered in geological formations like jagged cliffs and rocky outcroppings. Before you get into exploring, make sure you check out the Nature Center.
This structure is operated by The Council of Park Friends and is open seasonally based on weather. This group offers many educational classes and programs on subjects like geology, natural history, and park wildlife. Inside, you can experience many interactive displays that provide information on things like animal migration and ancient human occupation.
While canines aren't allowed inside of The Nature Center, there are several viewing platforms directly outside that you can explore with your dog, provided they are leashed up. The Nature Center also offers guided walking tours that leave from the main building every 90 minutes. Save for service animals; canines are not allowed to accompany guests on these tours.
If you are looking to enjoy Clark Reservation State Park's unique glacial plunge basin lake, swimming is available at no cost. Keep in mind, no lifeguards are on duty throughout the year, and you swim in these waters at your own risk. The waters in this lake are unique in that the upper and lower waters never mix, which makes it a hotspot for scuba training.
Hiking is very popular here as well, with over four miles of trails to climb. The majority of these trails follow the jagged edges surrounding the glacial lake and tend to bit a little bit challenging. That being said, due to these cliffs being some of the highest in the state you're bound to find some genuinely epic views. Canines are allowed to accompany you on these trails, provided they stay on a 6-foot leash or shorter.
