Lagoa do Fogo and Caldeira Velha, Sao Miguel

By the Travel Portugal Now team · Published 2 October 2026

Lagoa do Fogo, the “Lake of Fire”, is the wildest of São Miguel’s crater lakes. It lies high in the mountains in the centre of the island, inside a nature reserve with no buildings in sight. Here’s how to visit, plus the nearby hot springs of Caldeira Velha.

Quick answer: the lake lies on the mountain road between Ribeira Grande and Lagoa, about 30 to 40 minutes from Ponta Delgada. The roadside viewpoints give the classic view, and a steep trail leads down to the lakeshore. In busy months, access may be managed with a shuttle or road restrictions, so check before you go. Combine it with Caldeira Velha hot springs.

Crater lake

Visiting the lake

  • The viewpoints: several lookouts along the road give sweeping views into the crater and down to both coasts on a clear day.
  • The trail: a steep path descends to the white-sand shore. Allow time to climb back up.
  • Protected area: stay on the paths and take your litter with you.

Caldeira Velha

On the road down towards Ribeira Grande, Caldeira Velha is a nature park with a warm waterfall pool and hot springs among giant ferns. Entry is ticketed, and slots can sell out in summer, so book ahead.

Tips

  • Fog: the lake is often in cloud. Check the webcams and go when it’s clear.
  • Wind and cold: it’s much cooler up here than on the coast.
  • Parking at the viewpoints is limited.
  • Tours: many full-day São Miguel tours stop here. See São Miguel tours.
