Biosphere Pool Complex

A Unique Tropical Pool Paradise!

Hotel pools have become much more than a place to swim laps and burn off calories. A pool can also serve as a resort’s architectural and amenity focal point, offering a place to exercise or unwind. Grand Cascades Lodge has accomplished both scenarios with its extraordinary 10,000 sq ft tropical Biosphere pool complex.

The Biosphere is the first structure of its kind in the U.S. to incorporate advanced German Foiltec roofing material, allowing nearly 100% light transmission for year-round tanning. In addition, a retractable roof which produces an extraordinary outdoor effect is a truly singular offering in the Northeast. Furthermore, our exotic freeform pools are surrounded by lush tropical foliage which was specially transported to be housed in the Biosphere.

Grand Cascades Lodge guests are invited to enjoy and experience: 

  • Refreshing indoor and outdoor snow pools 
  • Spectacular views of the surrounding mountains
  • Underground aquarium
  • 140 foot water slide (48” height requirement to ride the Biosphere Slide) 
  • Grotto-like Jacuzzi (closed at this time)
  • Cave-themed steam room & sauna (closed at this time) 
  • The Biosphere Café featuring freshly made gelato, sandwiches, salads and imaginative tropical drinks 

Operating hours vary by day and season. Please contact   to confirm current hours.
