The largest indoor waterpark on the US’s east coast has opened in Pennsylvania as part of a US$163m (€145.3m, £107.3m) ski resort and spa development.

Supplied by WhiteWater West, the 130,000sq ft (12,140sq m) Aquatopia Indoor Waterpark on Camelback Mountain will operate all-year-round and features seven pools, 13 water slides, a surfing simulator, interactive water play centres, private cabanas and a swim up-bar.

The waterpark is home to some brand new concepts including: Storm Chaser, the longest uphill water coaster in any US indoor waterpark; Venus SlydeTrap, a multi-slide attraction combining three waterslides comprised of rafts, a serpentine flume, a 16-ft sphere and a zero-G open wall ride; The Lost River, a lazy river using immersive storytelling to create a dark adventure river experience; and Kartrite’s Quest, a play structure touted as ‘next generation,’ offering fully-themed and immersive multi-level exploration.

In addition, the waterpark has also incorporated WhiteWater’s popular Great Ka-Na-Gawa Wavepool, Bombora FlowRider surfing simulator, Mystic Springs indoor/outdoor family spa pool and several waterslides to appeal to all ages.

The 453-bedroom Camelback Lodge – owned and operated by the Camelback Lodge & Aquatopia Indoor Waterpark ownership group – offers free waterpark access to guests.
