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.

  1. 1
    Current-driven fish density

    Frequent strong flow concentrates barracuda, dentex and grouper around the rock at recreational depth.

  2. 2
    Two 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.

  3. 3
    Five-metre channel with Tascó Gros

    A short, fish-dense gap that local centres flag as the densest stretch of the dive.

  4. 4
    Eagle ray season Jun-Sep

    Diver logs across a decade describe groups of ten to fifteen passing through during summer.

  5. 5
    Gorgonian wall and macro stones

    Red gorgonians line the south wall; nudibranchs and crustaceans cluster on rocks at 22 m.

Difficulty & Certification

ModerateMin cert: OWNitrox recommended

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.

Frequently Asked Questions

Why is Tascó Petit harder than Tascó Gros?
Current. The two islets sit five metres apart, but Tascó Petit takes the flow that Tascó Gros shelters from. Diver logs across a decade describe conditions strong enough to abandon a planned circumnavigation, and the south wall adds a depth-management challenge that the calmer twin does not. The east shallow leg is gentler, but even there the current can reshape the dive plan on the way down.
Can Open Water divers dive Tascó Petit?
Yes, on the east shallow route in calm conditions and with a guide. Reserve rules require Open Water divers to be accompanied by a 3-star diver or instructor. Centres rotate to lee sites when wind builds, so an OW booking can be moved to a sheltered alternative. The south wall route is for AOW only.
When are the eagle rays around?
June through September is the consistent window. Diver logs across a decade describe groups of ten to fifteen passing through during summer, often on the east shallow route. They are not guaranteed on any single dive, but planning a trip in those months is the standard advice for divers chasing the encounter.
What makes the south wall a deco trap?
The gorgonian slope draws divers progressively deeper than they planned. The wall is visually rich from 30 m to 45 m and easy to follow down without registering the depth. Local guides flag this site specifically for monitoring the computer through the wall section. Setting a hard depth ceiling at 35 or 40 m before descent is the standard precaution.
Is the channel between Tascó Petit and Tascó Gros worth a separate look?
Yes. The 5 m gap is short but fish-dense, and on lower-current days the dive can cross it and continue around Tascó Gros for a multi-feature loop. On stronger-current days the channel sits at safety-stop depth and serves as a natural macro and biodiversity stretch at the end of the dive.
How cold is the water at depth in summer?
Sharp thermocline. Surface runs 22-24°C through July and August, with a drop to roughly 16-17°C below 15-18 m on the wall route. A 5 mm hooded wetsuit handles the surface but feels thin at depth on the longer profiles. A 6 mm or semi-dry is the safer call for repeated wall dives.
What is the Grandes Meros eco-route?
A cluster framing used by the Costa Brava centre association: Tascó Gros, Tascó Petit, Carall Bernat and Ferranelles together. The pitch is that this corner of the archipelago concentrates the largest groupers and the densest pelagic encounters, and centres often run a multi-dive day across the four sites.
