Ideal for families and groups, Roaring Springs Water Park has more than a dozen water-based rides, catering to all ages and tastes. From the undulating waters of the White Water Bay Wave Pool, swimmers can head to the gently flowing Endless River or the spiraling high-speed thrills of Viper's Vortex. Super Splash City has a bevy of water play areas and activities for younger children, while thrill-seekers can inner tube solo down the Pipeline Mines tubes or with a partner on The Avalanche. Set in the western Boise suburb of Meridian, the waterpark is just south off the interstate. « less
