I live near by to this state park and have spent much time exploring the entirety of it.

The trails are all nice, nothing too strenuous, and each have something unique compared to the others in the park. During the spring the Salamander trail is filled with thousands of Trilliums, a truly majestic experience. Lots of flowing water to enjoy throughout the park, some are off the trails but never hard to reach. A good park to enjoy with family and friends because you can fish, kayak, bike, skate, hike, horseback, and picnic. In addition, there are numerous historical cabins, locks, shelters, and a water run mill to sight-see. Then for those in search of a bit of spookiness, Gretchen’s Lock is notoriously a haunted location with certainly eerie vibes.

The family campground is small, but the park as a whole is not far from civilization so if any supplies are needed it is not a far endeavor. 

I do not horseback, so I cannot comment on that campground, but many of the trails are friendly for horses to travel.

OH! And if you are there on the weekends the Wildlife Center is a must! The staff are so nice, it is by donation to visit so is in everyone’s price range. An astounding display of animals and nature information! You can even hold the snakes and see a bee hive in action.
