Be sure to pack the kids' bikes, while adult bicycles can be rented on-site. The park has plenty of trails open to cyclists, which makes for another interesting way to take in the full scope of the park.
Visit the information center, see artillery gun batteries, and take a trip to the park's military museum. If you are visiting in the summer, go for a ride on a military transport truck and join an underground tour.
With the Coffenbury Lake and two smaller ones in the vicinity, water-loving visitors can enjoy swimming, canoeing, and fishing. You can also simply lounge on the lake's beach, and there is a boat ramp, too.
