Why Sao Miguel for Snorkeling
Sao Miguel is not a classic palm-fringed lagoon, but it is excellent for adventurous snorkelers who like lava pools, drop-offs and marine reserves. Natural pools at Mosteiros, rocky entries at Ponta da Galera and calm coves like Pedreira Beach reward confident swimmers with clear water and abundant small reef fish.

What to do when you are not in the water

Crater lakes like Sete Cidades and Lagoa do Fogo, hot-spring villages at Furnas, tea plantations, coastal viewpoints and whale-watching tours all run as easy day trips from Ponta Delgada.

Visibility often exceeds 25 m in summer, with thermoclines adding a technical edge.
