When you go to the Archipelago of Revillagigedo you want to see manta rays. A marine biology student recorded 330 different mantas in the archipelago in 3 years.
It's the manta rays that make The Boiler, San Benedicto, Mexico, one of the world's most famous dive sites.
One of our surprise visitors at the remote rock of Roca Partida was a baby humpback whale with its mother.
Roca Partida is the smallest island in the Revillagigedo Archipelago. It's 100 metres long and 8 metres wide; a piece of volcanic rock that has eroded over millennia.
Mexico's Revillagigedo Islands are a group of four volcanic islands in the Pacific Ocean.
As you arrive at San Benedicto in the Revillagigedo Islands, Silky sharks (Carcharhinus falciformis) come in to circle the boat.
The Silky shark (Carcharhinus falciformis) is one of the most common sharks at the Revillagigedo Islands.
Diving with Demoiselles
Few people but New Zealand scuba divers will understand my fascination with a slightly boring silver fish with two white spots. Those who've been completely immersed in a school of Demoiselles, surrounded in all directions, fish so close you could cradle them in your hands, will get it.
Taak Bi Ha
Cenote Taak Bi Ha has opened up for cave diving, snorkelling and swimming since our last Mexico cave diving trip. It has a stunning closed cavern that they light up for visitors. Taak Bi Ha is part of cave system Sac Actun.
Tank Cave - A3 intersection
Coming from the entrance of Tank Cave, this is the point at which the tunnels split. The A Tunnel leads off to the left and the C Tunnel continues straight ahead.
