Ponta Delgada, Portugal

Lagoa Do Fogo

This 'Lake of Fire' sits in the caldera of a 15,000 year old volcano.  

Hidden in the center of São Miguel island, in the Portuguese archipelago of the Azores, rests a shimmering blue crater lake known simply as Lagoa de Fogo or “Lake of Fire.”

At 3 km long and 2.5 km wide, the Lagoa de Fogo is one of the largest bodies of water in Portugal’s Azores region. The lake rests in the central caldera of the Água de Pau Massif, which is the youngest volcano on the island. Formed more than 15,000 years ago, the last recorded eruption of Água de Pau Massif occurred back in the 1500s. 

Today, the stunning lake is protected by the Portuguese government, which bans construction from unfolding around the lake in an effort to keep this historical volcano lake untouched and pristine.
