April through October offers the best weather and full access to trails, with peak fall foliage in mid-to-late October creating the most popular (and crowded) period. Spring brings wildflowers and fewer crowds, while summer provides warm weather ideal for waterfall visits but requires earliest booking for weekends.
The park spans multiple areas connected by state routes, with each major attraction (Old Man's Cave, Ash Cave, Cedar Falls, Rock House, Cantwell Cliffs) having separate parking areas and trailheads. A personal vehicle is essential for accessing different sections, as distances between areas range from 3-15 miles with no shuttle service.
Camping fees range from $20-$50 per night depending on site type and amenities, with park entrance included in camping costs. Ohio State Park passes provide free entry for day use but don't reduce camping fees. Reservation fees apply through the ReserveOhio system, and cancellation policies vary by site type.
Rock shelters book 6+ months ahead and offer primitive conditions with no electricity but include fireplaces where noted. All campgrounds enforce 7-day maximum stays, and pet policies allow dogs in most areas but require leashes. Water and restroom facilities are available throughout the park, but cell service can be spotty in remote areas.
