However, we were able to spend the rest of the morning exploring the wonderful hikes they have in the hills alongside and within the park territories. We took a short hike up the top of the hill with a gorgeous view of Puddingstone lake. Horseriding rentals are also nearby for longer trails around the surrounding mountainside.
For the kids, the playgrounds were impressive, they had a variety of them for different age levels and interaction. An interesting one was a playground that featured rope bridges that kids can traverse across or climb with playground-like bouldering.
There is a $10 entrance fee at the gates. They no longer offer boat or jet skis rentals on site, but they do allow you to bring your own watercraft for a launching fee. In the summer, a part of the lake is open for beach swimming but it can get extremely crowded.
Tip: Go early and avoid the crowds during the summer times. Even if you choose not to walk the mountain trails, the park is huge and offer nice walking/jogging along the lake that is flat and easily accessible.
