Pick an activity mode to compare signature sites, skill fit, and gear planning notes before you lock your trip.
Portugal is a high-variety Atlantic dive country. The mainland delivers rocky reefs, caves, and wreck days from Sesimbra, Peniche and Berlengas, and the warmer south coast around Algarve (Lagos). Madeira is the consistency play: reserve sites, clear water, and excellent shore access from Madeira. The Azores are the ambition layer, with blue-water drop-offs and offshore-bank attempts from bases like Ponta Delgada (Sao Miguel), Pico, and Faial. Plan around swell and wind, pack for thermoclines, and treat offshore days as optional highlights rather than guaranteed dives.

Portugal's warmest mainland water, with flexible site choice and plenty for mixed groups.
Madeira marine reserves

Azores gateway and mixed days
For a first Azores trip with easy logistics and strong topside options, start from Ponta Delgada (Sao Miguel).
Azores blue-water focus
When you want offshorebank attempts and classic Azores pelagics, build a split between Pico and Faial, with extra days for weather windows.
Sesimbra and Arrabida Marine Park
