FAQ

Real answers to the questions divers actually ask about Key Largo.

How deep is the Spiegel Grove?
The Spiegel Grove sits upright in ~134 ft with the bridge superstructure rising to ~50 ft. Most recreational divers do the top decks (60–80 ft). Penetration and deeper structure require advanced and wreck certifications.

Diving is year-round. June–August has the warmest water (84°F) and best wreck conditions. December–February is windier with bigger swells but the visibility on calm days can be incredible (100+ ft).
