8. Doors Off Over Kilauea

Found on: Norwegian Cruise Line

This is Hawaii's youngest and most active volcano, and you'll hover right above it — feeling the heat rising from just 500 feet below as you take in the view from your doorless whirlybird. Along the way in this four-seat chopper, you'll skim over gorgeous rainforest terrain, buzz a series of waterfalls at Rainbow Falls State Park, and get up close with Hawaii's biggest mountain, Mauna Loa.
