The terrain consists of hills and sandy, red, black waxy soils; cedar, and other trees.
Easy walk, heavily shaded trail. Cool rock features throughout the hike. Saw butterflies, birds, bees, and snakes. Climb the observation tower and gaze for miles towards Inks Lake and open farmland. You can also do a 1.5m guided tour (1.5 hours) into the caverns. It was a great way to cool down after the short hike. Definitely recommend you take the time to visit the caverns in addition to the trail.

Family friendly cavern tour. Took a backpack carrier for my 15 month old. She did great on the 1.5 mile tour.
