Why go

The lake offers a unique intersection of raw volcanic power and tranquil beauty. Visitors can witness the steaming fumaroles at the northern shore, explore the neo-Gothic Capela de Nossa Senhora das Vitórias, and enjoy the cooling, verdant atmosphere of the surrounding caldera forest.

Why you might skip it

Those expecting a remote, untouched wilderness may be disappointed by the highly developed tourist infrastructure, including paid parking and the persistent scent of sulfur that can be overwhelming for sensitive travelers.

What to do

Take the 9-kilometer perimeter trail which provides a gentle, flat walk around the lake with changing perspectives of the water and forest. Visit the Caldeiras da Lagoa das Furnas to see where traditional Cozido stew is buried in the hot volcanic soil.

History & origin

The lake occupies the crater of an active volcano last erupting in 1630. It has long been a site of human interest due to its geothermal energy, historically used for cooking, and is now protected as part of a landscape area within the Furnas Valley.

Getting there & around

Access by car via the EN2-1A road which circles the lake, offering multiple pull-outs and a main parking area near the caldeiras.

The site is easily navigated by a well-marked perimeter road and a flat, perimeter walking path. Internal access to the chapel and specific geothermal zones is mostly paved or gravel.

Common planning mistakes

Visitors often stick only to the caldeiras parking area and miss the serene walking paths on the south and west sides of the lake, which offer a much quieter experience.

Less ideal for

Visitors with severe respiratory issues sensitive to sulfur or those seeking a secluded, silent natural escape away from crowds.

Practical notes

Wear sturdy walking shoes if planning to hike the full perimeter. Bring a windbreaker as the weather in the caldera changes rapidly. Note that there is an entry fee for the Mata-Jardim José do Canto botanical area on the north shore.
