Summer Splash Getaway

Whisk your family away to northern Michigan before the sun sets on summer. A visit to Avalanche Bay this August not only offers you hours upon hours of splashing fun at Michigan's largest indoor waterpark, but a endless adventure - from Zipline Tours and yard games, to lounging on the shores of Deer Lake, and braving the world's longest timber-towered suspension bridge, SkyBridge Michigan.

Check out some splashtacular end of summer rates, starting at only $129 per night. Plus, as a lodging guest you'll score 10% off day passes at Avalanche Bay Indoor Waterpark.

But act fast! Don't let these summer savings swim by!
