Swimming on Pico: the lava pools at Santo António, Cachorro, Madalena and Lajes

Pico has hardly any sand. You swim off black lava, from ladders and concrete decks the villages have built into the rock, or in pools that fill and empty with the tide. There are plenty of these places, and the useful question is which one suits the day: which coast is calm, whether you want a café and a shower or an empty rock, and whether anyone is testing the water.

On that last point, each year the regional government publishes a list of official bathing zones, and for 2026 it named 26 on Pico, spread across the island's three municipalities. Those are the places where the water is sampled through the bathing season, which runs from June to September. Eleven of them also carried the 2026 Gold Quality award from Quercus, the Portuguese environmental group, which goes to bathing waters with an excellent record over several years. The list changes a little each spring, so check the current one before you plan around a particular spot.

Pico is long and narrow, with a north coast that faces São Jorge and a south coast that faces open ocean. A northerly swell can close the north-side pools for the day while the south side is flat, and a southerly swell does the same to the south. The two coasts are rarely more than half an hour apart by car, so on a rough morning the fix is usually to drive across the island rather than give up.

Whichever coast you choose, the entry is over rock and ladders. Bring water shoes, and do not assume there is a lifeguard: whether one is on duty depends on the place and the month, so look for the lifeguard post before you go in.

If you only swim once on Pico, this is the most complete option. The Furna sits below the village of Santo António in the municipality of São Roque do Pico. It combines open-sea swimming from ladders in the lava with two built pools on the deck above, which is useful if you are with children or the sea looks lively. There is a car park, and in 2026 it held both official bathing status and the Gold Quality award.

The rock shelf in front of it is also listed as a dive spot by the regional tourism board. According to the regional dive guide, the water starts at about 3 metres and drops to an average of 12, the area is sheltered, and there is an arch about 8 metres wide a short swim out. Marine life starts at the first rock wall, so a mask is worth bringing. It is about 25 minutes by car from Madalena.

The Garajau trail (PRC20PIC) starts and ends at these pools: a 7.8-kilometre loop, graded medium, about three hours, and São Jorge is across the channel from the pools. Walking it in the morning and swimming afterwards is a good way to spend a day on the north coast.

Cachorro, in the parish of Bandeiras between Madalena and São Roque, is a stretch of lava coast cut into arches and tunnels, with one rock that looks like a dog's head and gives the place its name. Underwater the arches continue, and the regional dive guide lists it as a dive site with weak currents, an average depth of 12 metres and a maximum of 18, suitable for beginners and snorkellers.

Cachorro was not on the 2026 list of official bathing zones, so nobody samples the water and there is no lifeguard, and the rocks are sharp. Go in on a flat day if you are a confident swimmer, or join a dive centre trip from Madalena if you want to see the tunnels properly. If you just want to swim, drive on to the Furna.

Madalena, where the ferry from Faial arrives, has eight official zones in 2026, and seven of them held Gold Quality: Madalena itself, Baixas, Barca, Cais Mourato, Criação Velha, Pocinho and São Mateus.

The town's own swimming spot is Areia Larga, a strip of dark shingle and flat rock just north of the harbour, about five minutes on foot from the ferry terminal. If you are on a day trip from Horta with an hour before the boat back, this is where to spend it. For something quieter, try Cais Mourato north of town, or Criação Velha to the south, among the stone-walled vineyards of the UNESCO landscape.

Lajes do Pico has a small pool built into the rock on the seaward side of the waterfront, a minute from the whaling museum and the harbour. The official list calls it Lajes (Maré), and it held Gold Quality in 2026. It is right in town, and it fills the time before a whale-watching trip leaves.

East and west of Lajes the municipality has eleven more official zones, the most of any on Pico. Santa Cruz das Ribeiras has pools and concrete terraces below the village and is the usual choice when the north coast is shut by swell. Manhenha, at the eastern tip, is where the Ponta da Ilha trail ends. Fonte and Admoiro are both on the Mistérios do Sul do Pico trail (PR15PIC), an easy 8.5-kilometre walk across the lava of 1718 and 1720, so you can stop for a swim halfway. See our guide to coastal walks on Pico for the details.

São Roque do Pico has six official zones. Two of them, Piscina do Cais and Poças de São Roque, are in and around the town and both held Gold Quality in 2026. Further east, Poça Branca at Prainha de Baixo is a single walled pool at the end of a narrow lane, with a deck and a shower and nothing else. There is no bar and no shade, and room for about six cars. On a weekday it is often empty.

• Children, or a sea that looks unsettled: Furna de Santo António, for the built pools
• Off the Faial ferry with an hour to spare: Areia Larga in Madalena
• Waiting for a whale-watching boat: the pool at Lajes
• North coast closed by swell: Santa Cruz das Ribeiras on the south side
• Snorkelling among arches, calm day, confident swimmer: Cachorro
• A pool to yourself: Poça Branca

Are there beaches on Pico?

Very few with sand. Swimming on Pico means natural pools and bathing areas cut into the lava, with ladders, decks and sometimes built pools. The regional list for 2026 named 26 official bathing zones on the island.

When is the swimming season on Pico?

The official bathing season, when the water at the listed zones is sampled, ran from June to September in 2026. People swim outside those months on warm days, but the facilities may be shut.

Is the water clean?

At the official zones it is tested through the season. Eleven Pico zones held the Quercus Gold Quality award in 2026, including Furna de Santo António, Lajes and most of the Madalena zones.

Can you swim at Cachorro?

You can, on a calm day, but it was not an official bathing zone in 2026, so there is no water testing or lifeguard. It is better known as a snorkelling and dive site, with arches and tunnels down to about 18 metres.
