The Bushy Run Battlefield is a must see experience in Jeannette. This park marks a Native American battlefield, and manages to be both beautiful and educational. There are tours and trails throughout the park! Your dog is welcome to join you as long as they are well-behaved, and you bring your own doggie bags.
If you're looking for something that won't require listening to a tour, check out Green Hills Park. This small, out of the way park is a great place to bring a large group. It's less crowded than larger parks. Your group can spread out to the picnic tables, playground, and sports fields to find something for everyone to enjoy!
Jeannette is a fantailstic place to visit!
