Quassy consists of a full-fledged amusement park plus a waterpark called Splash Away Bay.

In 1901, a writer pronounced Lake Quassapaug as "the handsomest bit of natural water on Earth".

Quassy offers swimming, picnicking, a catering service, an arcade, a waterpark, and live entertainment including school bands, dance groups and magic shows.

A wristband is required to enter the waterpark and beach area, or guests may pay a separate admission.

[1] Quassy originally opened as a trolley park, owned and operated by an electrified rail line.
