Frolicking in a 500,000-gallon wave pool, plummeting from 100-foot free-fall slides, and drifting along a 1,200-foot lazy river with 5 mph currents are just a few of the diversions found within Seven Peaks Water Park's net of water parks. The aquatic havens spread across Utah and Indiana, luring families and adventurous kayakers with forests of twisting water slides such as the Provo location's Boomerang, which sends passengers ricocheting down three stories. Calmer fun awaits at child-friendly areas such as Sand Bar Bay, where gentle spurts of water surprise and delight kids and a tiny slide sends them, careening and giggling, into the water.
