Las Galletas

Las Galletas, Tenerife · Canary Islands · Spain

Las Galletas is one of Tenerife's finest diving areas, a collection of volcanic reef sites scattered along the island's sheltered southern coast where warm Atlantic waters meet dramatic underwater lava formations. The small fishing village of Las Galletas, now a relaxed resort town, serves as the base for multiple dive centres that access over a dozen sites within a short boat ride. The underwater landscape is quintessentially Canarian: black volcanic rock formations create a maze of ridges, overhangs, tunnels, and sandy channels that harbour an extraordinary concentration of marine life. The volcanic substrate has been sculpted by millennia of erosion into fantastical shapes, creating a three-dimensional playground for divers at depths from 5 to 25 metres. The star attractions are the green sea turtles. Resident individuals, some with shells over a metre in diameter, are seen on virtually every dive, often resting on the reef or grazing on algae-covered rocks. The turtles are thoroughly habituated to divers and frequently allow close approach, making for spectacular photographs. Equally exciting are the angel sharks, a critically endangered species in most of European waters but still relatively common in the Canary Islands. These flat, beautifully camouflaged sharks rest on sandy patches between the lava formations, and a keen-eyed guide will spot several on a single dive, especially during the cooler months from October to March. Beyond these headline species, the reef is alive with Mediterranean and Atlantic crossover species. Large cuttlefish display their mesmerizing colour changes, trumpetfish hang vertically among sea grass, and schools of barracuda cruise the blue water above the reef. Moray eels occupy almost every suitable hole, and octopuses are common across the rocky terrain. At depth, conger eels and large stingrays can be found resting in the sand. The diving conditions at Las Galletas are among the most reliable in Europe. The south coast of Tenerife sits in the island's rain shadow, protected from the prevailing northerly trade winds, so calm seas are the norm. Water temperatures are comfortable year-round, ranging from 18 degrees in February to 25 degrees in September, and visibility regularly exceeds 20 metres. These conditions make Las Galletas equally appealing for beginners discovering the underwater world for the first time and experienced divers seeking reliable encounters with charismatic megafauna.
