Hamm
Shallow Islamorada patch reef with ledges and dense reef life.
Boat-access Upper Keys reef for easy reef-top cruising and ledge hunting; current can build, so keep the plan conservative.
About Hamm
Hamm is a shallow Islamorada patch reef with ledges around the outer edge and plenty of structure to hold fish life. It works best as a boat dive with a simple reef-top plan and a loose loop around the ledges. Expect dense schools of tropical fish plus sharks, eels, and smaller reef life tucked into cover. On calmer days it is straightforward, but the outer edge can feel more exposed when current builds.

Local Intel For Hamm
Community notes to help plan your visit.
Scuba Diving
Best as a boat dive with reef-top cruising and ledge exploration around the perimeter. Good for relaxed bottom time and fish watching when conditions stay settled.
Freediving
Workable for experienced freedivers in calm conditions, but keep the plan simple and conservative if current or chop is up.
Snorkeling
Snorkeling can work on calm days because the reef is shallow and easy to read from the surface. The better windows are when the water is settled and current is light.
