Dock wisdom

Stella Maris Resort runs the best diving operation on Long Island — book directly through them.

The shark dive at Stella Maris is world-class and extremely well-run — safe and spectacular.

Dean's Blue Hole itself has no dive operator on site — all diving is self-organized.

Bring your own snorkel gear to the blue hole; rental equipment is only at Stella Maris.

Operators are real local fixtures — confirm current sailing times and prices with each operator before you go. Countdowns run on the real local clock and the sunset sail time is computed from tonight’s actual sunset.
