The Corn Islands sit on reef that sees a fraction of the traffic of Belize or Roatán, and the diving is correspondingly undisturbed — walls, coral heads, nurse sharks, eagle rays, and visibility that runs to thirty metres in the calm months.
This is the dive centre on Big Corn, running courses and daily boats. February to May is the settled season; the Caribbean here is wet and windy for much of the rest of the year.
