Poseidon Pass

Ever wanted to breathe underwater in New York? Poseidon Pass runs SCUBA tours that let you explore the unexpected below the surface. They keep the focus on safe, guided dives; no open-water certification is required for beginner sessions. Groups head to local quarries and fresh-water sites where visibility can surprise even seasoned divers. Night dives add another layer—spotlights reveal fish behavior you’d miss at midday. For photographers, they carry strobes and housing so you can capture the scene without fiddling with gear mid-dive.

Midtown East places them inside a quiet stretch of East 56th Street, tucked between the East River and Park Avenue. The precise address is 405 E 56th St New York, NY 10022. Walk-ins are welcome for gear fitting; they simply ask you arrive fifteen minutes early. Their schedule mixes weekend matinee dives with weekday evening trips—check their social feed for daily departures. If you only have an hour during a layover, they’ll point you to express sessions that fit tight windows.

The shop stocks all sizes of wetsuits, masks, and fins so last-minute swaps don’t derail your plans. They also rent compact dive computers for divers who prefer not to bring their own. Regulators and BCDs come sanitized and pressure-tested before every tour. If you’re traveling with bulky gear, they’ll hold it at the dock free of charge while you change into your suit. Fresh water rinses are always on hand to flush salt before you pack up.
