Do you get dirty at Kualoa Ranch?

It depends which Kualoa activity you choose. The Movie Sites bus tour is clean — you ride an open-air vehicle and walk maintained paths, wearing whatever you'd wear sightseeing. The ATV tours will get you muddy, especially after rainfall — the off-road trails through the Ko'olau foothills kick up red volcanic mud. Kualoa specifically advises wearing clothes you don't mind dirtying for ATV tours. Closed-toe shoes are required for ATVs; sandals work for bus tours. The Jungle Expedition Jeep tour has moderate mud exposure. Secret Island beach involves water activities — bring a swimsuit. Kualoa does not have on-site showers or laundry. Plan to return to your hotel before evening plans if you do an ATV tour. Wear your least-precious clothing and leave nice shoes in the car.
