Neshaminy State Park is located in Bensalem. From what I have seen the park is pretty extensive. It has a swimming pool, horse stables, and a beautiful marina of its own as well as plenty of running and walking trails. It has a playground to bring the kids as well, so it is a very family-friendly park. The pool looked amazing as it had 2 slides. The park when I visited was still being worked on by landscapers and I even had the chance to run into a park ranger.
My guess is that the pool will not be open at least until July if it opens at all. but the ground are beautiful and there is a piece of the park the allows you to look into the city. i saw a ton of people walking their dogs when I went to visit the park.
I’ve given you all enough insight into the park now it up to you to go and explore here is the address:
3401 State Road. Bensalem, PA 19020
