Beaches, skate parks, mini-golf, arcades, movie houses, surf lessons, ice cream worth the wait, public courts, library teen rooms, and the summer day camps worth a weekly drop-off.

The historic Main Street theater. Rebuilt after the 2016 fire as a nonprofit arthouse. Three screens, a lobby cafe, and a programming slate that mixes first-run indies, restorations, and teen-friendly classics.

The Sag Harbor line is the line. Cash, Main Street, 30 flavors, and a wait that stretches down the block on July Saturdays. Worth it if you haven't had the pistachio.
For parents: Cash only at the window. Expect a 20-minute line in peak weeks.
Coffee · Sag Harbor
Where the Sag Harbor teenagers actually are on a summer night. The froyo counter halfway up Main Street runs to 10pm Sunday through Thursday and 11pm on Friday and Saturday — later than anything else on the block that will serve someone under 21. Build-your-own frozen yogurt, made-to-order crepes and waffles, bubble tea, and a real dairy-free lane including a coconut-milk matcha shake.
For parents: Summer season only, open to 10pm most nights and 11pm on weekends. Main Street is walkable for drop-off, and the wharf is two minutes away.

The Cinema's after-dark program — midnight cult screenings, 35mm horror, director Q&As. Ticketed, no bar issue, and the crowd skews 18-30. The quietest good time on the East End after 10pm.

Coffee · Sag Harbor
The Main Street coffee bar that stays open late enough to actually be a hangout. No bar, no carding, no dress code. Cold-brew on tap, wifi, and the couches in the back room are the closest thing Sag Harbor has to a common area.
For parents: Long hours, late close in summer.

What’s strictly enforced out here
🪪 Drinking age is 21, and the East End enforces it harder than most of the state.
🏖️ Beach parking permits are real — and at 16 you can hold your own.
🚗 Licences come in tiers, and the curfew is not a suggestion — Suffolk County cops write tickets that stick.
🌊 Beach rules worth knowing before you pick a spot.
When in doubt: see safety for tick checks, water conditions, and lifeguard hours, and see concierge for emergency contacts, urgent-care locations, and the after-hours numbers that locals keep on a fridge magnet.
