Giving the only formal Spanish lessons on Utila, the Central America Spanish school is a mainland institute that takes advantage of the island's sun and laidback learning environment. They also offer weeklong packages that are paired with PADI certification. So, you can learn to speak Spanish and dive all in the same week for probably the lowest price you might ever find (L7,600/$400). Housing is available for an extra L2,280/$120 per week.
