9 Great places to go diving in Portugal

1. Northern Portugal

From north to south, Portugal boasts an array of landscapes above and below the waterline. The northern region is greener than the south, with numerous natural parks, historical sites and thriving cities. Together they offer plentiful wine and foodie delights plus stunning architecture.

While diving in northern Portugal isn’t at the top of most divers wish lists, it is well worth diving there. There is a surprising number of wrecks, underwater rock formations, canyons and swim-throughs to explore. All of which are teeming with fish life.

Top dives sites in the area include Bezerros, Pêlo Negro, the sunken cruise ship Ruy Barbosa, and the famous U-1277, a German submarine from WWII.

2. Central Portugal

Portugal’s central region is more mountainous than the north and is swathed in fragrant pine and chestnut forests. History buffs will enjoy the historic villages and old stone castles dotted among Central Portugal’s mountains, whilst divers explore the wind-swept coast.

Big wave surfers flock to world-famous Nazaré in Central Portugal for its epic waves and long beach. Take a short boat ride from Peniche and you’ll be among some of Portugal’s top dive sites. But before you hop on a boat, make sure you dive around Peniche. There are plenty of options for diving off the beach and around Peniche Fortress’s inlets.
