Go underground into the world’s longest known cave system, with more than 426 surveyed miles and new passages still being mapped. Above it, the Green and Nolin river valleys and south-central Kentucky karst hills turn Mammoth Cave into a multi-day landscape rather than a single cave tour.

This is the universal core. NPS explicitly states RVs, trailers and buses have no size restrictions on main park roads; large rigs should avoid the ferry and evaluate secondary roads separately.
Current-condition note: Road status can change; ferry and some secondary routes have separate restrictions.
Large powered and towed rigs must match current site limits. No regular water or electric hookups are provided; the dump station is at the adjacent service center.
Current-condition note: Main campground season is currently March 1 through November 30; confirm current dates before arrival.
Optional route only. Large rigs should route around via public highways rather than planning around the ferry.
Current-condition note: Ferry status changes with Green River levels and operational conditions.
