Cova Tamariu

The park's own underwater-itinerary chart drops a single marked point here, right against the printed -31 metre figure, inside a dense contour band that runs from about -25 to -34 metres. Despite the cave in its name (cova is Catalan for cave), the chart shows no overhead passage at this point, only open, contoured seabed. Two of the six species the sheet illustrates for this exact spot get their own location icons on the same chart: a cluster of yellow cluster anemone and a stand of red coral, each pinned to a specific spot in the contour pattern. Dusky grouper and forkbeard work the same depth band, with common octopus denning in the rock nearby.

Cova Tamariu earns its place on the map through the Catalan park authority's own itinerary programme: a dedicated eco-briefing sheet, an exact coordinate and an illustrated species list.1 That sheet tags this specific point inside one of Cap de Creus's three marine Partial Nature Reserves and marks a single surveyed depth of roughly 31 metres, deep enough to call for Deep certification.

The sheet for this exact point carries a no-touch and no-fishing icon plus two 1.5-metre clearance markers, one from the reef wall and one from the seabed, on top of the park's standing rule against touching or removing anything anywhere in the reserve. Independent diving is allowed park-wide with prior notice, capped at six dives a day, thirty a week and 120 a year per boat, not per individual diver. At roughly 31 metres this point works below the area's typical summer thermocline, near 15 metres: budget for cold water close to 14 degC at working depth, not the warmer layer near the surface.
