Ned Thomas Cay - Malpelo Island
Ned Thomas Cay, part of the wider Malpelo Island system, often delivers a solid dive. We’ve found the reef here is home to schools of snapper and barracuda, typically cruising past the wall. Keep an eye out for the resident white-tip reef sharks, often resting in the sandy patches just off the main drop-off. It’s a good spot for divers comfortable with drift dives, as currents can pick up, making for an exhilarating ride along the reef's edge. This isn't usually the "big ticket" Malpelo experience, but it’s consistently interesting and a good place to appreciate the sheer volume of fish.
