Indoor & Family Things to Do on Long Island
Rain, cold weather or a scorching July afternoon doesn't have to cancel the day. Long Island's museums, aquariums, theater and planetariums offer real experiences for different ages without depending on beach weather.
I'm John Cordeira, Broker/Owner of Cordeira Homes. I help people explore Long Island beyond real estate, and this resource is one part of our growing guide to useful, interesting local places across Nassau and Suffolk.
Nassau County Indoor Attractions
Garden City's Museum Row is a strong place to begin.
Garden City | Nassau
Cradle of Aviation Museum
Aircraft and spacecraft displays plus planetarium programs. A great choice for curious school-aged kids and adults.
Garden City | Nassau
Nunley's Carousel
A historic carousel that can add a shorter treat to a museum visit; hours and tickets may differ from museum access.
Garden City | Nassau
Garden City After the Museum
Pair one museum with lunch rather than filling the day with too many stops. Explore restaurants and nearby businesses.
Suffolk County Indoor Attractions
These spots are worth planning around, not just using as a last-minute fallback.
Riverhead | Suffolk
Long Island Aquarium
Aquatic exhibits indoors, with separate animal encounters and seasonal activities available under different rules.
Centerport | Suffolk
Vanderbilt Museum and Planetarium
Explore collections and planetarium presentations; different portions of the property may have different schedules.
Stony Brook | Suffolk
The Long Island Museum
Art, history and exhibits for visitors interested in Long Island's culture and heritage.
Babylon Village | Suffolk

The Argyle stages children's productions alongside its professional theater calendar, making a live-performance outing possible.
Plan the Right Outing
Match the age and energy: For preschoolers, look for hands-on galleries. For older children, science, space and aquariums can work well. Check timed shows, accessibility and holiday closures before booking.
Official websites above have the most current hours, admission rules, weather updates and tickets. This guide was researched in October 2026; dates should be reviewed for each new season.
