 To walk in nature is to witness a thousand miracles.

During a 16-day camping trip in July 2025 with our daughter and her family, we spent a week in northwestern Pennsylvania so we could explore some state parks in the area. This blog entry features three parks we visited on one day during our stay in the area.

Jennings Environmental Center

The Jennings Environmental Education Center, located in Slippery Rock, Pennsylvania, is one of several state parks dedicated to providing environmental education and recreational programs to the public. The park has over 5 miles of hiking trails. It has areas for picnicking and wildlife watching and has many events and workshops open to the public throughout the year.

Jennings has a unique combination of prairie and forest environments. Most of the park is covered by forest that includes streams and wetlands. One of the park’s main features is the 20-acre prairie ecosystem, a home to prairie plants. It features the beautiful blazing star prairie flower. We were happy to see that they were in full bloom during our visit. There were also signs letting us know that the endangered massasauga rattlesnake could be found there. Thankfully, we didn’t see any snakes while we were there!

We wandered along the Prairie Loop Trail, stopping to take photos of the many wildflowers that were in bloom. We saw quite a few we hadn't seen before and one we couldn't identify. It was a really nice park to explore. It would be nice to come back again in spring to see what's blooming then.

  

Moraine State Park

Moraine State Park is located near Portersville in western Pennsylvania, about an hour north of Pittsburgh. It’s a huge park, covering 16,725 acres and featuring the 3,225-acre Lake Arthur. It’s a very popular park. Each year over a million people visit it for fishing, boating, wildlife watching, picnicking, disc golfing, hiking, biking, horseback riding and swimming. Although camping in the park is limited to organized groups, there are 11 modern cabins available for rent to visitors year round.

Moraine State Park gets its name from the hilly deposits of gravel, sand and clay that were deposited there about 12,500 years ago. Today, in addition to the man-made Lake Arthur, the gently rolling hills and lush forests leave visitors with plenty of room to explore.

Lake Arthur features 42 miles of shoreline and nine public boat launches for boats with up to 20 horsepower motors. In addition, there’s a privately owned/operated boat rental facility on the south shore with everything from kayaks to motorized pontoon boats. The lake was used to portray New York’s Hudson River in the movie “The Pale Blue Eye”, starring Christian Bale.

In addition to the numerous boat launches and fishing jetties, the lake has two “swim at your own risk” beaches; one on the north shore and one on the south shore. The lake is stocked with muskellunge, walleye, channel catfish, bass, northern pike, bluegills and crappies, making it a popular spot for fishermen.

State Park Marina

Our main reason for visiting the park was so that we could ride our bicycles on a paved, 7.1-mile long multi-use trail. The trail winds along the north shore of Lake Arthur between the Bike Rental Building in the northwest corner of the park and the Davis Hollow Marina, where it dead ends. The trail was mostly shaded with a few small hills here and there, making for a very pleasant ride. After returning to our start we enjoyed our lunch at a shaded picnic table before heading to our last stop of the day.

Cascade Park

Although it's not a state park, Cascade Park, located near downtown New Castle, Pennsylvania, was next on our list. It's a former amusement park that operated from 1897 until the early 1980s. The park was home to roller coasters, many amusement rides, and what at one time was the largest dance hall in Pennsylvania.

Big Run Falls is a 20 to 25-foot-tall waterfall located in the center of the park along the edge of a very large hollow. This circular area makes it hard to get close to the falls, but it also offers a great overlook from which to view it. The viewing area is located next to the roadway through Cascade Park and close to a parking area, making it a very easy waterfall to visit.

Just downstream from the waterfall, we could see some of the rails that used to be part of the Comet, a roller coaster that was built in 1955 and used to dive into the valley near the waterfall. We also saw the remains of a swimming pool and several buildings that used to house amusement park rides and concession stands. The 1898 dance pavilion still stands near the entrance to the park.

Cascade Park was a nice way to end our day. Seeing the old buildings brought back happy memories of amusement parks we had visited in our youth.
