Snorkel the Florida Keys Reefs: Half-Day Trip from Key Largo
Step off the Reefhouse dock and into some of the only living coral reef in the continental U.S. This half-day snorkel from Key Largo visits two protected reef sites—turtles, rays and the Christ of the Abyss are possible highlights—while giving practical tips to stay safe and leave no trace.
The Experience
Before You Go
Bring reef-safe sunscreen
Use only reef-safe, mineral sunscreen and apply it well before entering the water to protect coral and comply with local guidance.
Wear a snorkel vest if unsure
Even if you're a competent swimmer, a snorkel vest adds buoyancy and conserves energy during long surface swims.
Prepare for boat motion
If you get seasick, take medication 30–60 minutes before departure and sit in the middle of the boat to reduce roll.
Respect marine life and reef structures
Avoid touching, standing on or collecting coral—disturbance damages reefs and is often illegal within protected zones.

Conservation Note
The area is part of the Florida Keys National Marine Sanctuary with active reef restoration and rules to limit anchoring and fishing; visitors are encouraged to use reef-safe products and avoid touching coral.
The Keys formed from ancient coral and limestone terraces; sites like Pennekamp were among the first marine preserves in the U.S., established to protect reef habitat and shipwrecks.
