Arenal Diving Ibiza
PADI 5 Star Dive Resort in San Antonio, operating since 2004 with a four-boat fleet covering Ibiza's west-coast caves, gorgonian walls, and the Don Pedro wreck.
Also known as: El Dado, Es Dau Petit, Small Dice
Rock islet five minutes from Ibiza port, multi-level 4 to 30m, programmed by local centres as the second tank of a Don Pedro day.
Last updated May 2026
A typical descent works the wall side first when groups want depth. The wall faces southeast and drops in steps of large fallen rock blocks to about 28 to 30m, with craters and crevices holding the resident moray and conger eels and the spiny lobsters that locals point out as a reliable feature. From there the route loops back along the pinnacle face, where small-fish density picks up: damselfish, rainbow wrasse, painted combers, dentex passing in pairs, the occasional barracuda school. The shallows reward slow swimming. The 4 to 10m rocks carry hydrozoan colonies, yellow anemones, sponges, and algae, the macro layer that drives the winter nudibranch reputation. The dive is open water on both faces, depth-banded rather than feature-banded, with no overhead environments and no signature passages. That is its strength as the second tank of a Don Pedro day: a guide can hold a mixed-certification group on the pinnacle and let advanced divers drop to the wall, all within boat-sight of one mooring.
Three things distinguish this islet from comparable Ibiza sites. First is the Don Pedro pairing. Most divers reach Dado Pequeño as the shallower second dive on a Don Pedro day, and the operational logic shapes the experience: divers arrive already framed by the wreck, looking for fauna they can spend a full no-deco bottom time with rather than a feature-led tour. Second is the multi-level structure. A pinnacle plus a wall, both on a single mooring, is uncommon at this depth range and lets centres run mixed groups without splitting boats. Third is the winter macro reputation. The shallow colonised rocks attract the kind of nudibranch density that draws photographers in cold months, when the rest of the island's programme thins to weather-window dives.
Despite some operator marketing, the islet sits outside the formal boundary of the Reserva Marina dels Freus, which covers the strait between Ibiza and Formentera further south. No reserve permit is required to dive here, and standard centre packages cover the trip. Most operators run the Don Pedro and Dado Pequeño combination as a two-tank morning, departing Marina Botafoch around 09:00 and returning before 13:30. The site is less weather-sensitive than exposed western or northern sites because of its shelter near the port. Expect 19C bottom water in shoulder months, dropping to 14C in February; budget a 5mm wetsuit for May and September, 7mm with hood for winter, 3mm only for shallow summer profiles. Standard recreational kit is enough; SMB and dive computer are essential given the proximity to commercial boat traffic on the surface.
What makes this dive site stand out.
Run as the second tank by the centres that work the wreck, same boat run from Ibiza port
Pinnacle thick with small fish on one side, southeast wall of fallen blocks on the other
OW divers stay on the pinnacle, advanced drop to the wall, all within sight of one boat
Shallow rocks colonised by hydrozoans and anemones; macro hunting peaks in cold months
One of the closest serious dives to the port of Ibiza, rarely weather-limited
38.8822°N, 1.4778°E
Shoulder months balance warm water, peak visibility, and fewer crowds. October is specifically called out for this site.

OW divers stay on the pinnacle and shallow reef. Advanced certification recommended for any wall exploration past 18m.
Summary
Easy on the pinnacle and shallows, moderate on the wall blocks. The multi-level structure suits mixed-certification groups.

Same boat run and complementary depths. Don Pedro sits at 27 to 47m and is the deeper first dive; Dado Pequeño's 4 to 30m profile lets divers off-gas while still seeing dense fauna. The two sites are minutes apart, and the rock is the one the wreck struck in 2007.
Local marketing sometimes claims so, but the formal Reserva Marina dels Freus d'Eivissa i Formentera covers the strait between the two islands, well south of the central zone where the islet sits. Treat the reserve framing as overstated.
Yes. The pinnacle and shallow rocks (4 to 18m) are within Open Water limits, and the multi-level structure lets a guide hold OW divers shallow while advanced divers drop to the wall. The wall side past 20m is more appropriate for Advanced certification.
May to June and September to October give the best balance of warm water (19-24C), peak visibility, and fewer crowds. October is the season most often singled out for this site. Winter shifts the focus to macro photography of nudibranchs on the shallow rocks.
About five minutes from Marina Botafoch and the port of Ibiza, and about twenty minutes from the port of Formentera.
Generally no. The islet sits in a sheltered position relative to the more exposed western pinnacles like Es Vedra or La Bota. Mild current is possible but unusual; one logged dive in May 2019 reported none.
