Photo: Flip Schulke, Public domainWalk off a sandy beach into shallow, buoyed water, no boat needed. Bahia Honda is the Keys' easiest way in. Decide whether the shore fish are enough, or join the park's own boat to Looe Key. The old railroad bridge makes a fine backdrop, though the channel beneath it is no place for a casual swim.
Shore snorkeling here is gentle and modest. Expect seagrass, rocks and small, young fish rather than coral. The most life sits on the rocks and breakwater on the bay side, where snappers, grunts and sergeant majors gather, with the odd butterflyfish or parrotfish. Poke around the grass and you may find a spiny lobster or a scorpionfish. Visibility can be poor when sediment is up. For living reef, take the park boat to Looe Key.
A small bay-side beach at the foot of the old bridge. A buoyed, lifeguarded snorkel zone runs along about 200 m of beach with water up to about 6 ft. Enter at the eastern end near the rocks.
On the southern shore of the key. One guide suggests it for better snorkeling when the sea is calm. Details are thin, so ask a ranger about conditions that day.
A section of the Flagler railroad bridge you can walk out on for views. Snorkel near it with great care because of the current below.
The park concession runs a three-hour trip to Looe Key reef in the sanctuary, with about 1.5 hours of snorkel time.
A small yellow and silver damselfish with five black bars. Bold and curious, it is often the first fish to swim up to you on a Florida reef.
Abudefduf saxatilis
Yellow fish with blue or bronze stripes that hang in big, slow schools under ledges and around coral heads on Florida reefs.
Haemulon
Colorful grazers with fused, beak-like teeth. You can hear them crunch on coral rock, and much of the white sand on tropical beaches passes through them.
Scaridae
A silver snapper with a bright yellow stripe and forked tail that schools over Florida reefs, often hovering right below snorkelers.
Ocyurus chrysurus
Clawless lobsters with long antennae poking out from under ledges. Caribbean spiny lobster live on Florida reefs and California spiny lobster in kelp and rock.
Panulirus
Small, disc-shaped fish in yellow, white and black patterns, usually seen in pairs. Many feed on coral polyps, so they are a good sign of a healthy reef.
