Scenic Lagoa do Fogo, in central Sao Miguel Azores, is nestled within a deep, lushly-vegetated volcanic caldera. This stunning lake, the second largest on Sao Miguel, is often overlooked.
To ensure you don’t miss visiting this magnificent area, here are three different ways to experience Lagoa do Fogo, the Lake of Fire.
Lagoa do Fogo – An Azores Geosite
Lagoa do Fogo sits within the caldera of the Fogo Volcano. The caldera, shaped like an irregular bowl, is about 400 metres deep and 2.8 kilometres across. Its slopes are steep and rough, covered with natural woodlands and abundant, diverse endemic plants. The lake itself is 30 metres deep. The area covered by the caldera and the lake is classified as a nature reserve and an Azores geosite.
How to Visit Lagoa do Fogo
Fogo Lake is a short drive from the major centers of Ponta Delgada and Ribeira Grande. We recommend renting a car to visit, although some tourists join organized tours as well.
Depending on how much time you have, here are three different ways to see Lagoa do Fogo.
Enjoy the views of the amazing caldera and lake from miradouros along the regional road.
- Hike to the Beach
Walk the short path down to the western edge of the lake from the Miradouro da Lagoa do Fogo Viewpoint.
- Half day Hike
Take a hike up the trail on the southern side of the caldera to the southeast shore of Fogo Lake.

Lagoa do Fogo Viewpoints
Along the main road, two viewpoints allow different views of the lake and the surrounding countryside.
Miradouro da Barrosa Viewpoint
The most southerly viewpoint is on the regional road adjacent to Pico da Barrosa. This area offers great views of the whole Serra de Água de Pau Protected Area, Fogo Lake and even the north coast of São Miguel. This is the highest point in the central part of Sao Miguel at close to 950 metres above sea level. You can walk up the service road beside the radio antennas to get closer to the peak. The regional road loops back on itself here and has parking areas along each leg.
Miradouro da Lagoa do Fogo Viewpoint
This viewpoint is the closest to the lake and the start of the trail down to the beach. From the viewpoint look out over the Caldeira do Vulcão do Fogo and down to the lake.
A bit further north on the regional road is Miradouro da Bela Vista Viewpoint. While there isn’t a view of Fogo Lake here, take a minute to visit. This panoramic view of the north coast from Ribeira Grande all the way west to the volcanic crater of Sete Cidades is truly a lovely “bela” view.
Lagoa do Fogo Hike to Beach
Many visitors enjoy the invigorating hike down to explore the western beach of Fogo Lake. Its pumice beach is one of the 7 best wild beaches in Portugal.
Start your hike from the Fogo Lake Viewpoint. There is lots of parking and the trailhead to the beach is easy to find. The area is often wet and muddy so be prepared with appropriate footwear. Be careful on the 500-metre walk down to the pumice beach. It is quite steep.
The path along the north shore of the lake runs for about 2.5 kilometres. Explore as much of it as you want. Return to the viewpoint on the same path.
Be aware that there are no facilities at the lake (no toilets or garbage cans). Whatever you carry in, please carry back out.
Lagoa do Fogo Hiking Trail (PRC02)
If you have most of a day to explore the area, the Lagoa do Fogo trail (PRC02) is a great option.
The trail begins in farm pastures to the south and climbs to the shore of Fogo Lake. See the ruins of a factory which produced fiber from flax plants. Cross an irrigation channel which will likely be muddy. Along the way you’ll find endemic Azorean blueberries, heather and laurel plants.
The trail enters the caldera on the south side. Explore the lake’s pumice beach. Return to your starting point by the same path enjoying the downhill journey with views of the south coast and the Islet of Vila Franca.
It is about 11 kilometres round-trip and takes 4 hours plus the time spent at the lake.
If you want to hike but don’t have 4+ hours, an alternative is the PRC29 SMI Caldeiras da Ribeira Grande – Salto do Cabrito. This is a shorter option located north of Lake Fogo. It is a circular hike with several uphill sections and takes about 2.5 hours. The hike visits a dam and associated hydroelectric power plant as well as the 20-metre high Salto do Cabrito waterfall. Termas das Caldeiras, close to the trailhead, is a small commercial operation with hot springs, bathing and spa facilities.

Fogo Volcano – The Geology of Fogo Volcano
A number of volcanic events created Sao Miguel starting about 4 million years ago. Over the last 800,000 years, three stratovolcanos (Sete Cidades, Fogo and Furnas) and a series of smaller cones added land on the western edge of the original volcanic island.
Fogo Volcano, the central stratovolcano, formed in the last 300,000 years. The volcano no longer has the familiar cone shape. About 15,000 years ago, the cone collapsed creating the depression called Caldeira do Fogo Volcano. It is the smallest and youngest caldera on the island.
Over time, Lagoa do Fogo formed in part of the caldera. The water from the lake feeds many springs and supports the ground water supply for several local municipalities.
Fogo’s last volcanic activity occurred in 1564 on the north coast at Ribeira Seca. Geothermal energy is present at Fogo Volcano on its north flank at a depth of about 800 metres. Two geothermal power plants, Cachaco-Lombadas and Pico Vermelho, use this energy to produce electricity. This energy also heats the ground water producing the secondary volcanic features of hot springs and fumeroles enjoyed at Caldera Velha Natural Monument and Termas das Caldeiras.
Day Trip – Caldera Velha Natural Monument
After exploring Fogo Lake, it’s time to head up the road to Caldera Velha. Relax in the hot, tranquil thermal pools at this beautiful natural area.
Visiting both Caldera Velha and Lagoa do Fogo is a great Azores day trip.
