An 11-ton geodesic dome houses one of the nation's largest IMAX theaters, and a tower capped with a glass observation deck provides a view of the Manhattan skyline.

Open daily 9:30am-5:30pm, April 1- Labor Day; Tuesday-Sunday 9:30am-5:30pm the rest of the year. Children under 12 must be with an adult.
