Scuba Diving in Portugal

Portugal is the westernmost state of continental Eurasia, located on the Iberian Peninsula and washed by the Atlantic Ocean. Here you can find some popular diving destinations, such as the Azores (Portuguese: Açores) — a picturesque group of nine islands far off the coast, and the Madeira Archipelago. Local waters are favourable for diving all the year round because the temperature never drops below +16 °C. You can dive directly from the shore: the main deepwater attractions do not require a boat journey. Underwater landscapes, numerous grottos and caves, inhabited by a range of sea creatures from barracudas and moonyfish to sharks, make diving in Portugal interesting. There are also a lot of sites for exciting wreck diving by the shore.

Reasons to Visit

Where to go
in Portugal?
Coral reefs near Madeira Island. In many countries, corals suffer from global warming and water pollution. The first sign of their destruction is fading colour. Portuguese reefs haven't been damaged yet and stay as bright as they were thousands of years ago. Divers might wish to take photos near the coral walls and tropical fish hiding among the corals.
Various and rare marine dwellers. Blue sharks and whale sharks, sperm whales, barracudas, stingrays and dolphins are found near the Azores (Portuguese: Açores). Many of them are dangerous to humans, and at some dive spots diving is allowed only with experienced instructors. Tentacles of local octopuses could reach one meter in length.
The world's largest underwater park in Algarve Province will be completed in a few years. But this wonderful place is worth visiting right now before it will be crowded with tourists. Two warships have been decommissioned from the Portuguese Navy and sent to the bottom near the shore so that together with a few more wrecks they would comprise one of the largest artificial reefs in the world.
A lot of wrecks from different centuries. This place has been an important military facility throughout history, and a destination for different many ships. Wreck divers will be interested in a huge vessel called Terceirense lying 21 meters deep, and the 80 metre-long Norwegian steamboat, which sunk near Sagres in 1917 and now lies 28 to 32 meters deep.
Night diving at Reis Magos near Madeira. Here you can come across sharks, sleeping fish and still seahorses among the seaweed, or octopuses that start hunting at night. It is curious to observe a parrotfish getting inside protective cocoons to hide from predators.

Diving Destinations in Portugal

The best dive sites in Portugal are the Azore Islands (Portuguese: Açores) and the Madeira Archipelago. The surroundings of Algarve Province is a perfect place for wreck diving enthusiasts. The seabed near Madeira is covered with peculiarly shaped reefs and caves, and underwater photographs taken here are especially impressive. Besides, it is home for rays, dolphins and many species of fish. Due to the distance between the islands and the mainland, fewer tourists come to the Azores, while the sea life is more varied. In some places, you can even try diving with whales.

It is also recommended to get vaccinations against other diseases (the flu, tetanus, MMR) and to purchase a travel health insurance. Despite high healthcare standards, even first aid will not be provided without a health insurance card or payment in cash.
Portugal is relatively safe, however, tourists should beware of fraudsters and pocket pickers in public transport (underground, buses). It is better to keep your passport and cash money in the safe in your hotel.

Dangerous Marine Life

Local sea creatures that you should avoid include the large poisonous Chrysaora and rabbitfish. This fish never attacks, but you can hurt yourself with its poisonous spine by accident.

Eat & Drinks

The traditional Portuguese cuisine was created by peasants and fishermen, so all the dishes are hearty and simple. Any tourist should try Bacalhau — dried cod served with chickpeas. Fish lovers will enjoy Tamboril — it is a roast angler served with rice. Appetisers served in local restaurants may include a fish stew called Caldeirada, or Sopa de Pedra — a soup with beans, a pig's ear, potatoes, carrots, onions and... a little stone. Portugal cannot be imagined without its famous wines and ports. If you don't like wine, you can try Portuguese Coral Beer. It strongly compliments dishes with dried fish. Tap water in the country is clean and suitable for drinking.
