Haunted Tree House at Long Island Aquarium
October 2-31, 2026

The Long Island Aquarium's outdoor Tree House is transformed for Halloween, offering a nighttime adventure that is spooky but not too scary. Kids ages 3 to 11 can climb through all five levels at their own pace, decorate a pumpkin, make a Halloween craft, collect a bag of candy, meet an animal, and color their own button. After dark, the climbing structure feels like a completely different place.
Fridays and Saturdays in October, from 7:00 pm to 9:00 pm, after the aquarium closes for the day. For kids ages 3 to 11. Admission is $25 per child, and one accompanying parent is free. The Tree House is outdoors and runs weather permitting.
Details are on the Haunted Tree House page at Long Island Aquarium.
