Furnas Hot Springs and Thermal Baths

Most visitors come to Furnas to relax in the Furnas thermal baths.  The parish has two commercial hot springs facilities:

  • Poca da Dona Beija
  • Terra Nostra Thermal Pool in Terra Nostra Park

Poca da Dona Beija

The Poca da Dona Beija hot springs features 5 thermal pools, each a different temperature. The mineral-rich water from the local hot springs is collected and distributed to the pools in this outdoor spa.  The Poca da Dona is very popular.  It can get crowded, so arrive early.

Terra Nostra Park

Visitors to Parque Terra Nostra enjoy the thermal pool’s therapeutic waters and wander the 12.5 hectare botanical garden. Both are open to the public, subject to an admission fee, from 10:00 to 18:00 daily.

It all began over two hundred ago as the summer residence of Thomas Hickling, US Consul in Sao Miguel. At the front of his home was a small thermal pool. The whole property was planted with trees, many native to North America. The pool and woods are at the core of the park today.

Terra Nostra Thermal Pool

The large thermal swimming pool sits near the entrance to Terra Nostra Park. The local hot springs supply the pool’s orangey-brown waters. The water temperature ranges from 35C to 40C degrees. While the colour may be unappealing, the iron-rich waters are very therapeutic.

The Terra Nostra hot springs are one of a number of springs in the area. While hot springs can be found on most of the Azores islands, the Furnas Valley Azores hot springs have attracted international visitors since the late 18th century.  The thermal pool at Terra Nostra Park was built in 1780 and expanded in 1935.

Terra Nostra Garden

Parque Terra Nostra includes one of the largest and oldest botanical gardens in Europe. The map provided at the entrance, highlights a 3-kilometre walking path through the various themed gardens, with many other intertwining paths throughout. It is an incredible place to spend an hour or two.

Water features, benches and memorials to people important in the history of the garden are tucked into nooks planned among the flowers, shrubs and trees.

Terra Nostra Garden Hotel

One of the perks of staying at Terra Nostra Garden Hotel is access to the Terra Nostra Park’s Thermal Pools at any time. The hotel also has spa facilities which take advantage of the therapeutic waters of the hot springs.

The original hotel opened in 1935 when Furnas became famous for its thermal waters. The hotel has 2 wings of rooms: the original Art Deco Wing, and the Jardim Wing that was added in the 1990’s.

Furnas Lake

More attractions can be found to the southwest of the village around beautiful Lagoa das Furnas.  It’s a lovely spot, enjoyed by locals and tourists alike. Recent projects have reintroduced many endemic and native plants to the area which was heavily deforested over the years.

The main road EN1-1A hugs the eastern shore of the Furnas Lagoon. Parking is available on the southeastern and the north sides. Here are some of the things you’ll find travelling counter-clockwise around the lake, starting in the north.

There are fumeroles, geysers and mudpots at Furnas Lake.

Caldeiras da Lagoa das Furnas

The caldera, on the bank of Lake Furnas, has bubbling mudpots, small geysers and fumaroles venting hot steam and volcanic gas. The temperature underground reaches almost 100C degrees. The caldera has become famous for its use as an oven to cook traditional Portuguese Stew.

Large heavy pots, filled with bite-sized pieces of meat and vegetables, are lowered into holes dug in the hot ground. Over the next six hours, the stew cooks, taking advantage of the natural heat. Arrive around the noon hour to watch the local restaurants arrive to pick up their pots of finished stew ready to be served in their restaurants.

What is Furnas Stew?

Cozidos das Furnas is the local version of Cozido à Portuguesa, a traditional Portuguese boiled meal. Considered a national dish of Portugal, variations exist throughout the country. It is prepared with a multitude of different meats and vegetables depending on local availability. Traditional seasonings are red pepper paste, white pepper and cinnamon.

The local version typically includes beef, pork, chicken, chorizo sausage, streaky bacon and belly pork. Vegetables such as cabbage, potatoes, carrots and collard greens are usually used. What makes Furnas Stew unique among Portuguese stews is that it is cooked in a hole dug in the natural caldera. Be sure to try it when you visit.

You’ll find the entrance to the area’s newest attraction beside the caldera.

Parque Grena

This nature park has five kilometres of paths through an 18-hectare wooded area. Follow the stream to the beautiful Salto da Inglensa waterfall at the top of the slope. Climb up 633 steps to a viewpoint of the waterfall and the whole valley.

Parque Grena is a nature park with forested paths to explore.

There are spots to sit and enjoy a picnic or to just relax in nature. Paths lead to the ruins of a manor house called Grena, built in the mid-1800’s. Over the years, the property fell into disrepair. It was sold in 2018. After a year of extensive work, this beautiful nature park opened to the public in 2019.

The park has kayaks and bicycles for rent. Open year-round from 9:30 to 17:00, summer hours are extended to 18:00. There is an entrance fee.

Continue to the modern building tucked into the edge of the lake.

Furnas Monitoring and Research Centre

Centro de Monitorização e Investigação das Furnas is both a visitor centre and a research centre. It provides information about the volcanic history of the Furnas area. Learn about the area’s designation as an Azores Geosite and the efforts underway to protect and restore the ecosystems in this Sao Miguel protected landscape area.

It contains Lagoa das Furnas, the village of Furnas, several small volcanic cones, fumerole fields and a variety of mineral and thermal springs.

The centre has won a number of awards for its presentation of scientific information in ways that everyone can understand. This is a great place to learn about geodiversity, biodiversity, sustainability and local culture.

There are picnic facilities nearby with a beautiful view over the lake and of the colourful buildings along the lakeshore. These buildings and the surrounding gardens are what remains of a large 19th century country estate owned by wealthy landowner Jose do Canto and his wife. The land is still controlled by the family.

Mata Jardim Jose do Canto includes the chapel, two lakefront houses and the beautiful garden.

Mata Jardim Jose do Canto

The Jose do Canto Woods Garden, on the south bank of Lago de Furnas, has a number of walking paths and a quiet stream. Places to sit and enjoy the ten-hectare garden are scattered throughout. A trail leads to the Salto do Rosal waterfall in the south part of the garden.

The garden follows a plan created by a well-known Parisian landscape architect in the mid-19th century.  The design includes landscapes of diverse plant species imported from nurseries around the world and bordered by walking paths. Centuries-old Camellia trees line the Alameda das Camelias path and bloom vividly from January to March.

The garden is open everyday in the summer from 10:00 to 18:00. Winter hours are Tuesday to Sunday, 10:00 to 17:00. There is a nominal entrance fee. The current estate includes the garden, 2 houses on the edge of the lagoon, and the Chapel of Our Lady of Victories.

Capela Nossa Senhora das Vitorias Furnas Lake
The chapel was built by Jose do Canto as the mausoleum for him and his wife.

Capela Nossa Senhora das Vitorias

This funerary chapel was commissioned by José do Canto in the 1860s and is the final resting place of him and his wife, Maria Guilhermina do Canto.

Famous for its 13, three-metre high, stained-glass windows, it is one of very few neo-gothic buildings in Portugal. It makes a stunning site on the south shore of Furnas Lake.

Casa dos Barcos and Casa da Lagoa

These two pretty houses, built in the 1860’s, are available for short-term rental. The Anglo-Flemish House of Boats was the family’s boat pavilion. The French-Swiss chalet was referred to as pavilhao da pesca or the fishing lodge.

Furnas Hikes

There are two hikes which explore the area around Lake Furnas.

Lagoa das Furnas Hike (PRC06)

While the trailhead is in the village of Furnas, the trail circles Furnas Lake. This is a great way to leave the car behind and walk to many of the places on our itinerary. The path follows either parish streets or the hard-packed paths at the lake.

The trailhead is at the intersection of EN1-1A and Rua dos Fundadores do Futebol Clube Vale Formoso. There is lots of parking along the short street to the west and at the football stadium at the end of the street.

Follow the signs through the village, passing Igreja de Santana and Poça da Dona Beija. The trail winds its way toward Pico do Milho and Miradouro do Lombo dos Milhos Viewpoint where you’ll enjoy the view of the Furnas valley.

Walk southwest to Lagoa das Furnas. Travelling clockwise around the lake, you’ll pass the Chapel of Nossa Senhora das Vitórias, Mata Jardim José do Canto, and the Furnas Monitoring and Research Center. Along the way stop at one of the largest araucaria trees in Europe.

After Parque Grena, see the geysers at the Caldeiras da Lagoa das Furnas. Follow the lane back to the regional road EN1-1A. Walk left along the road to the first street which leads back to the starting point. The full walk is about 9.5 kilometres. The hike just around the lake is about 6 kilometres.

Salto do Rosal Waterfall Hike

Looking for a relatively short walk through a forest to a pretty waterfall?  This is the perfect hike.

The trail is completely within Jose do Canto Garden Woods so a small admission fee applies. Fully shaded, this makes a great hike for a hot day or a hike in the heat of the day. See many non-native species of trees and explore the rest of the garden after your hike.

Explore the Town of Furnas

Walking around town, you’ll pass several noteworthy buildings.

Igreja de Santa Ana was built in 1760 and is one of the oldest churches on the island of Sao Miguel.  The site held the first temple in the Furnas Valley, said to have been part of a convent founded by hermit priests.  The chapel and convent were destroyed in the last volcanic eruption in the area in 1630.

The Myrtle Stream flows through the quiet village park.

The paths of Parque Dona Beatriz do Canto, in the center of the village, follow the Myrtle Stream as it crosses Furnas. The 3.7-hectare garden dates back to the mid-1800’s.  The wide paths lead to both grassy areas and dense woods, surrounding a lake fed by water from the stream.

Igreja De Nossa Senhora da Alegria (Church of our Lady of Joy) sits in the center of the village. The beautiful twin-spired church overlooks Parque Terra Nostra.

Just down the street from the church you won’t miss Casa Invertida, a unique building that hides an electrical substation.

Here are five of the most popular restaurants in the village.

  • Tony’s Restaurant Furnas
  • Terra Nostra Restaurant
  • Summer Breeze
  • Caldeiras e Volcoes Restaurante
  • A Terra Fornaria

Tony’s Restaurant is the most famous for serving Furnas Stew.  Many other restaurants also serve the local stew or some variation of it.  We enjoyed the food and casual atmosphere at Summer Breeze.

Local restaurants such as Tony’s use the Furnas Lake Caldera to cook their pots of Furnas Stew.

Furnas Viewpoints

Miradouro do Lombo dos Milhos Viewpoint

Enjoy a picnic high on a hilltop south of the village with a panoramic view of Furnas and the surrounding hills. To find this viewpoint, just look for the radio towers.

Miradouro das Pedras do Galego Viewpoint

From this viewpoint on the north side of Furnas, on EN2-1A, you’ll get a different perspective of the village, a corner of the lake and the crater’s north edge.

Miradouro do Salto do Cavalo Viewpoint

Northeast of the village, in beautiful thick forest terrain, this viewpoint is off the beaten path.  If you make the effort to go, be sure it is a clear day. You’ll have panoramic views overlooking the Furnas Valley and the island’s north and south shores.

Furnas Side Trips

When travelling from Ponta Delgada to Furnas, we highly recommend these two additional attractions.

Vila Franca do Campo Islet

This nature reserve and Azores geosite lies about half a kilometre offshore of the village of Vila Franca do Campo. About 8 hectares in area, it is the eroded remnant of an ancient submarine volcano estimated to have erupted about 4,000 to 5,000 years old.  The well-defined, circular crater, about 150 metres in diameter, is filled with ocean water. With crystal clear waters and a small beach, it is a great place for divers and bathers.

Vila Franca do Campo Islet Sao Miguel
Vila Franca do Campo Islet is the ruins of an ancient submarine volcanic cone. Several plant and animal species are protected here due to its designation as a nature reserve.

Regular boat connections, from Tagarete Pier in Vila Franca do Campo, are available during bathing season June to October. It is very popular during the summer for swimming, diving and bird watching. Only 400 people are allowed per day to help protect the native vegetation and seabird habitat.

There are toilette facilities, changing rooms and guards in the swimming area. The average seawater temperature is 21C degrees.

Ermida de Nossa Senhora da Paz

Our Lady of Peace Chapel is a 16th century pilgrim chapel.  Restored numerous times, the chapel is located high on a hilltop, just above the Miradouro da Senhora da Paz Viewpoint.

Vila Franca do Campo and islet Sao Miguel
The view of Vila Franca do Campo and the islet from the top of the Mount of Our Lady of Peace is impressive.

At 215 metres above sea level, you’ll enjoy the panoramic view of the village, the islet of Vila Franca do Campo and the ocean.

Not only is the surrounding landscape beautiful, the chapel’s entrance staircase, built in 1968, is unlike most other rural chapels.

Staircase with 10 landings and Our Lady of Peace Chapel
The stunning staircase has 10 landings and 10 steps between each landing.

The staircase has 10 landings and every landing has a typical Portuguese azulejo tiled panel. Each panel commemorates one of the first ten Mysteries of the Holy Rosary, a set of Catholic prayers.  Ten steps lead to each landing and represent the ten “Hail Mary” prayers said during the recitation of the Holy Rosary. For the best pictures of the staircase, try to visit in the morning.
