"If you do nothing else on the Big Island, do the volcano," advises Fodor's. Since its eruption began in 1983, Kilauea Volcano has steadily been "oozing new layers of lava onto its flanks," creating a show of "fire, earth, and water." With this deal for $35 per person (reg. $74), see the volcano and Big Island's other top sights on a full-day guided tour that includes Hawaii Volcanoes National Park, Thurston Lava Tube and the "magical" Rainbow Falls.
