The Maritime Aquarium at Norwalk is a highly accessible and spacious option for a Chol Hamoed family trip, conveniently located right off I-95 with covered parking right next door. Unlike generic aquariums, this one focuses specifically on the Long Island Sound ecosystem, featuring a wide mix of animals ranging from harbor seals and sea turtles to meerkats and otters. It’s incredibly hands-on for kids, offering unique touch experiences where they can actually interact with stingrays, sharks, and jellyfish. While there are cafes on-site, they aren't kosher, so you'll want to pack your own holiday meals or snacks for the day. Between the interactive exhibits and the optional 4D theater, it’s an easy, indoor-friendly way to keep everyone entertained for hours.

Admission is $39.95 for adults, $34.95 for seniors aged 65 and over, and $29.95 for children ages 3 to 12, while children under 3 years old are admitted free.
