Tascó Petit
Current-swept islet at the southern Medes, paired with Tascó Gros across a 5 m channel; barracuda schools, large groupers and seasonal eagle rays.

The dive
Two routes off the same buoy, and the current picks. Heading east toward Carall Bernat, a reef shoulder runs at 5 to 25 metres past grouper holding station against the flow, sea bream species stacked in mid-water, and morays watching from crevices. Eagle rays move through this stretch in summer, sometimes in groups of ten to fifteen on a single dive. Drop the other way and the south wall begins at 30 metres along the buoy line, then peels off down a gorgonian slope toward 40 to 45 metres. Red Paramuricea clavata covers the wall below 15 metres. Large groupers occupy ledges, scorpionfish settle motionless on the rock, and dentex patrol the upper edge while barracuda hunt bogas higher in the column. Connecting the two routes is the 5 metre channel with Tascó Gros, short but packed enough that local centres call it the densest stretch of the dive. Brief current direction with the guide before descent; on stronger days the team works one side and ascends back to the buoy on the lee.

What makes it special
Tascó Petit is the current-driven member of the Grandes Meros cluster. The Costa Brava centre association markets the site alongside Tascó Gros, Carall Bernat and Ferranelles as the corner of the archipelago where the largest groupers concentrate and pelagic encounters peak. What separates this islet from its neighbours is exposure. The flow that other sites shelter from is the reason fish stack up here, and the Spanish forum description of enormous schools of pollack, jack, dentex and large barracuda surrounding divers at just 18 metres matches what the Dutch dive-log corpus shows over a decade of repeat visits. Two profiles off one mooring is the practical advantage. A buddy team can split levels, and the same boat trip can run a beginner-friendly east leg alongside an AOW wall route.
Photographer's notes
The south side at 22 metres is the macro stop. Local centres flag this stretch specifically for nudibranchs, crustaceans and small organisms tucked into the rocks, and the relatively shallow depth keeps no-decompression time generous for working a single subject. For wide-angle, the south wall delivers the gorgonian-and-grouper backdrop on the deeper route, with barracuda schools higher in the column when the current runs. The 5 metre channel works as a close-focus zone at safety-stop depth on the way back to the boat. Light fades fast on the wall; an off-camera strobe or a steady backup torch helps on the gorgonian sections below 25 metres.
Know before you go
Brief the current with the guide before descent. The flow direction on entry decides whether the team can circumnavigate or runs a one-sided profile, and asking the question on the boat is faster than working it out underwater. On the south wall, set a hard depth ceiling before descent and check the computer through the gorgonian section, which draws divers deeper than they plan. EAN32 is the standard recommendation for any 30 m profile here. Carry an SMB and deploy from depth before the ascent: pleasure boats use the archipelago in summer. Surface temperature in July and August reads 22 to 24°C, but a sharp thermocline drops the wall route to roughly 16-17°C below 15-18 m, so plan exposure protection for the bottom rather than the boat.
Why Dive Tascó Petit
What makes this dive site stand out.
- 1Current-driven fish density
Frequent strong flow concentrates barracuda, dentex and grouper around the rock at recreational depth.
- 2Two routes off one buoy
East shallow leg toward Carall Bernat (5-25 m) and a south wall to 40-45 m share the same mooring.
- 3Five-metre channel with Tascó Gros
A short, fish-dense gap that local centres flag as the densest stretch of the dive.
- 4Eagle ray season Jun-Sep
Diver logs across a decade describe groups of ten to fifteen passing through during summer.
- 5Gorgonian wall and macro stones
Red gorgonians line the south wall; nudibranchs and crustaceans cluster on rocks at 22 m.

Conditions
Difficulty & Certification
Easy to advanced depending on route. Strong current is the recurring complication and makes this site noticeably more demanding than its twin Tascó Gros, even on the shallow leg.
