Underwater reef at Malmok
Declining

Malmok

Aruba · Caribbean

Malmok beach on Aruba's leeward northwest shore sits above the Antilla, a 400-ft German freighter scuttled in 1940 — the Caribbean's largest accessible wreck. The site's sheltered from Aruba's near constant trade wind, giving year round diveable conditions in warm, clear water.

How this reef is doing

How we measure this

Reef state

Declining

The Antilla wreck is the headline dive and is not coral dependent — encrusted hull sections and resident fish life remain excellent. Living reef around Malmok has thinned since 2014 but Aruba's cooler, calmer conditions mean it fares better than many northern Caribbean sites.

What divers say

The Antilla is the rare Caribbean wreck where you can genuinely spend a whole week diving the same site and still find new rooms.

Truck rental

Most dive ops offer a gear and truck package. Worth it for the independence to hit the site before the crowds.
