Batelão do Burgau

Also known as: Batelão, Burgau Barge, Burgau Wreck

A small barge wrecked in a 1980s Algarve storm, now a shallow 6-8m artificial reef off Burgau prized for macro life on an otherwise bare sand plain.

Last updated September 2026

The dive

Burgau beach is close enough to swim from: a direct 200-250 metre swim, or a short boat hop, reaches a flat sand plain where the wreck resolves out of it as a single intact hull, roughly 25 metres long, encrusted and settled, bow toward shore. At 6-8 metres the dive typically stays close to the structure itself, working recesses and plating instead of covering distance: black-faced blennies and gobies hold on the encrusted surfaces, and nudibranchs work the corroded steel. Either approach suits a relaxed two-tank morning.

What makes it special

On an otherwise bare stretch of sand, one isolated hull works as a magnet: octopus and cuttlefish tuck into the plating, two-banded bream and other sargo circle past, and a macro cast of blennies and nudibranchs covers the crevices. The barge is believed to have belonged to an old stone quarry at Ponta de Almádena, sinking here in a storm during the 1980s while carrying stone for the Portimão harbour mole; it is sometimes described instead as an older tugboat lost around 60 years ago.1 The pull here is entirely that concentration effect: a single point of hard structure holding species that the bare sand around it would otherwise scatter.

Know before you go

Venomous scorpionfish sit camouflaged on the hull's encrusted plating; a sting brings pain and swelling that lasts up to 12 hours, so keep hands away from surfaces you can't see into. Green anemone and trumpet anemone cover the same plating and sting on contact too, so scan ledges visually and keep hands off them. The wreck sits close to a popular beach with real recreational boat traffic, especially in summer; the municipal source that surveys the site names a marker buoy and dive flag a priority requirement here, not a suggestion.

    Octopus, cuttlefish, blennies and nudibranchs work the hull, the only structure around

  3. Shore swim or short boat hop

    Reached by a 200-250m swim from Burgau beach, or a quick boat ride

  4. A quiet, repeat dive

    Divers and freedivers return to film it again and again

ModerateMin cert: Open Water

The only source with a formal grade calls the dive Medium and names Open Water Diver as the minimum; a dive catalogue instead calls it easy and relaxing. Expect a straightforward but not throwaway dive.

Summary

The shallow depth invites divers in; the Medium grade signals it isn't automatically an easy dive.

Frequently Asked Questions

Is Batelão do Burgau really as deep as 10 metres, or does it top out at 8?▾

The commonly cited figure is 6 metres average, 8 metres maximum, matched exactly by a dive catalogue's own listing, and this page treats that as the wreck's own depth. A couple of write-ups instead give up to 10 metres for the wider site around the hull, not the wreck itself. Expect the dive to play out at 6-8 metres, with a slightly deeper surrounding area some write-ups fold into the same figure.

Was Batelão do Burgau a stone barge or a tugboat?▾

Most likely a barge. It's recorded as a small barge that sank in a 1980s storm while hauling stone for the Portimão harbour mole. One operator's own site instead describes a tugboat sunk about 60 years ago, a different vessel entirely. The tugboat account stands alone against the more detailed storm history, so this page treats the barge story as the primary account and the tugboat description as one operator's own characterisation.

Is night diving worth trying at Batelão do Burgau?▾

Divers have filmed at least one night dive here, so it's clearly done in practice, but no source says whether it's recommended over a day dive or what changes once the sun goes down. Ask your operator for their own read on it before booking a night slot.

Does Subnauta still run trips to Batelão do Burgau?▾

Unclear. Subnauta has a 2014 video of this exact wreck from its own channel, but its website is currently unreachable, and a wider check of the area's operators found signs it may have wound down since the pandemic. Confirm directly before booking through them. Blue Ocean Divers, based between Sagres and Lagos, names this wreck on its current site.
