This is a rugged 0.75 mile loop trail. This self-guided nature trail through Ogle Hollow Nature Preserve describes natural aspects of the park. The trail starts near the paved park road north of the Rally Campground and continues down a wooded slope, where yellowwood trees exist. The pileated woodpecker has been observed in the area through which this passes. Trail 5 returns near the Rally Campground, where it connects with Trail 4.
