Diving and snorkelling on Graciosa: the Terceirense wreck, the Carapacho cave and the reefs off Santa Cruz

Almost every dive on Graciosa starts with a boat ride of between two and twenty-five minutes from one of the island's two harbours, Santa Cruz on the north coast or Praia on the east. What you need to settle before you go is which sites match your certification, which months give the clearest water, and where to snorkel if you would rather stay at the surface.

Of the Graciosa sites on the official Azores diving portal, dive.visitazores.com, only one is a shore dive, from the Santa Cruz quay. The rest are boat dives. Which harbour the boat leaves from depends on the weather, and so does the site: a south wind favours the north coast reefs, and when the north side is rough the sheltered sites off Carapacho are the fallback.

The regional tourism board lists two dive centres on the island, both in Santa Cruz da Graciosa:

• DivinGraciosa, Rua Corpo Santo 11, which runs boat dives, try dives, snorkelling trips and blue shark dives.
• Gracipescas, Rua Serpa Pinto 1, a sea activities company running since 2001 that also offers try dives, snorkelling, whale watching, boat and kayak trips.

Neither publishes a price list online as of 2026, so write or ring ahead with your dates, your certification and the number of dives you want.

Here are eight of the sites the portal describes, with the depths it gives.

• Restinga do Freire starts at the Santa Cruz quay at 7 metres and slopes down to 15. The portal recommends it for night dives as well as first dives. Even inside the harbour you see octopus, moray eels and, lower down, dusky and island groupers.
• Ilhéu da Gaivota is a small islet about 50 metres off the Carapacho bathing area on the south coast. The wall drops to a sandy bottom at 14 metres, with an average depth of 9. Currents are weak, and it is the site the boats fall back on when the weather rules out everything else. Common eagle rays rest on the sand at the end of the wall.

DivinGraciosa runs its try dives in calm, shallow water, from the quay steps or the boat, down to 4 to 6 metres with an instructor beside you. The minimum age is 10, and minors need a parent's authorisation.

• The Terceirense wreck is, in the portal's words, one of the best and most popular dives on the island. The ship, about 40 metres long, sank in 1968 at the entrance to Praia harbour and lies at around 21 metres, two minutes by boat from the quay. You cannot get inside any large part of it. The stern and its propeller are the most intact sections, and the scattered hull, pipes and boilers are full of groupers, conger eels and morays.
• The Gruta do Carapacho is a 50-metre crack in the largest of the Carapacho islets, with a cave on its south wall. Most of it is a cavern open to the surface, and daylight reaches down to about 17 metres. Look on the walls for nudibranchs, including the Azorean Hypselodoris picta azorica. Outside the crack the dive can go to 32 metres.
• Baixa do Farol is on the north coast, about 100 metres off the Ponta da Barca lighthouse and ten minutes from Santa Cruz. The first reef tops out at 14 to 15 metres, and a second, deeper one has a small cave where dusky groupers and barred hogfish live, with black coral nearby. This is the site for days with a south wind.

• Baixa do Ferreiro de Fora, seven minutes from Santa Cruz, is a reef that rises to 7 metres and falls to 44. The top works as a safety stop, the platform at 15 metres is where schools of almaco jacks, white trevallies and barracudas pass, and black coral grows further down, towards 28 metres. Currents here are moderate.
• Baixa do Terceirense is a different site from the wreck, despite the name: a reef about 100 metres off the smallest Carapacho islet, stepping down from 5 metres to platforms at 16 and 30 and a bottom at 40.
• Baixa da Senhora da Guia sits 200 metres off Praia and 50 metres from the Ilhéu da Praia, the seabird reserve. Its top is only 3 to 8 metres down, so snorkellers can use it too, and the wall below has a small cave and black coral at 16 metres.

Blue sharks pass the Azores on their migration, and DivinGraciosa takes divers out to meet them in open water a few miles offshore. The dive is shallow, to about 10 metres, but there is no wall or bottom to orient by, so you need good buoyancy control. The sharks are 1.5 to 2 metres long and come close. The operator recommends July to November.

You do not need a dive centre to see fish on Graciosa. Barro Vermelho, on the north coast, is a bay where a lava ridge closes off a shallow lagoon of pebbles and red sand. At low or half tide the water inside is about waist deep and full of fish. Go on a falling tide, when the lagoon is widest and clearest. It has a lifeguard in season, showers and toilets, but no café, so bring water.

The Carapacho pools on the south coast are the other option, mainly when a north wind spoils the north shore. Beyond the pool edges is open sea, so stay inside unless the water is flat and the lifeguard is on.

The diving portal gives average sea temperatures of 16 to 22°C across the year, peaking at 24 to 25°C. The best months are June to September. From August into September or October, visibility often goes past 30 metres. In spring the water carries more nutrients, turns slightly green and drops to 10 to 15 metres of visibility.

For a suit, the portal suggests 5 or 7 mm from June to October and 7 to 10 mm, or a drysuit, from November to May.

The hyperbaric chamber for the central islands is at Horta Hospital on Faial, 46 nautical miles from Graciosa, and a diver with decompression sickness goes there by sea or air. In an emergency call 112. That distance is a reason to dive conservatively, stay well inside your limits on the deeper reefs and leave a proper gap before your flight off the island.

Can you dive on Graciosa without a certification?

Yes, with a try dive. DivinGraciosa runs them in calm, shallow water to 4 to 6 metres with an instructor, from age 10.

What is the best dive on Graciosa?

The diving portal calls the Terceirense wreck one of the best and most popular: a 40-metre ship that sank in 1968 at the entrance to Praia harbour and lies at about 21 metres. The Carapacho cave is the other one to ask for.

Where can you snorkel on Graciosa from the shore?

Barro Vermelho on the north coast, inside the lava ridge at low or half tide. The Carapacho pools on the south coast are the alternative when the wind is from the north.

How much does a dive cost on Graciosa?
