Caldeira Velha Hot Springs in Sao Miguel Azores – Time Slot Entry Tickets

Caldeira Velha Hot Springs in Sao Miguel Azores – Time Slot Entry Tickets


When Is the Best Time

The thermal springs and pools of Caldeira Velha are located in the heart of Sao Miguel, the biggest island of the Azores. These hot springs and pools nestled in the rainforest with giant fern trees are a natural wonder that attracts visitors worldwide therefore, it became a Nature Reserve in 2008.

Caldeira Velha is a geothermal phenomenon and a unique experience close to Lagoa do Fogo. The Azores are of volcanic origin, and some of these volcanoes on Sao Miguel are still active. Caldeira Velha is remotely located on the northern flank of Fogo Lake and Volcano.

Huge fern trees like in New Zealand
The fantastic nature inside the park.

I will give you all information on how to secure a ticket online in advance, the best time, the water temperature for each pool and what to bring to this fantastic place in Sao Miguel.

At least people with disabilities have the opportunity to get a closer look. Opposite the entrance is a small parking reserved for taxis and people with disabilities. The path inside is paved and cobbled, accessible by wheelchair. 

Fumaroles and Three Pools

The boiling and bubbling hot water.
Boiling hot, not accessible.

Caldeira Velha, in the middle of the rainforest, is a haven to soak in the beauty of the Azores while enjoying the hot pools. Before you reach the second pool, you cross a wooden bridge which leads above a bubbling pond. You can smell the sulphur of the fumaroles, the evidence of volcanic activity. The fumaroles are openings like cracks or holes in this pond, they heat the water between 60°C and 100°C – boiling water. 

The information sign for the 100°C hot water.
Signs indicate the temperatures.

The springs and pools are fed by waterfalls and a network of underground thermal streams, which provide a steady flow of naturally heated water. Visitors can enjoy three thermal pool areas, ranging in temperature from lukewarm to warm and hot, all surrounded by lush vegetation and the sound of cascading water.

1 Pool and Waterfall

Visitors in the most popular pool in front of the waterfall.
This is the biggest and coldest pool.

The main pool is the biggest and the most picturesque, with the waterfall in the back. The water temperature is cool compared to the other ones, around 25°C. We got the recommendation to access this pool first, and I agree. Be careful the steps which lead into the pool are slippery. I was glad to wear my Teva.

2 Pool After the Fumaroles

The second pool with fewer visitors
My favourite pool because the hottest.

This pool was the warmest, reaching a temperature of at least 38°C. This was my favourite pool because of the temp, but I felt cold when I got out. Although it was September, I was freezing after this pool because of the high elevation it is cooler here.

3 Two Pools at the Beginning

The slightly colder pools to the right at the beginning
The temperature was around 36°C.

These two pools are slightly colder, with a limit of 9 and 6 people, but usually, no one cares about it. You first cross a wooden bridge to get to these pools.

Best Time to Visit Caldeira Velha

The waterfall and pool empty without anybody.
We had the last entry slot therefore, it became tranquil in the park shortly before closure. 

Visiting the thermal pools is great throughout the year. The most pleasant months regarding temperatures are May to October. Caldeira Velha is perfect for a rainy day. You don’t care when you are in the hot pools in this breathtaking nature. The pools are located at higher elevations of more than 600 m above sea level with high humidity. Therefore, it is always cooler at Caldeira Velha than at sea. 

The Azores are less busy in the winter however, it is the most popular time for the locals. The best daytime is either in the morning when the park opens at 9 am, after 1 pm at lunchtime, or in the evening for the last admission. Sao Miguel and Pico are popular destinations for residents from mainland Portugal, especially from Lisbon in the summertime; July and August are the busiest. If possible, avoid these two months.

Blue hydrangea are everywhere in the Azopres
My favourite month for the Azores is June when the blue hydrangeas are in full bloom.

Packing Checklist

  • A bottle of water - there is no cafe inside.
  • Older swimwear and towel - the iron reach water can react to your clothes, but Parque Terra Nostra was the worst.
  • Either flip flops to change from pool to pool or Teva. I preferred my Teva because some areas were slippy.
  • You may like to wear a warm sweater after your visit from fall to spring when day temps are not high.
  • Leave your valuables in your accommodation.

Top Tip

Fogo Lake nearby
The Fogo Crater Lake is a short drive from Caldeira Velha.

I highly recommend hiking at Fogo Lake in the morning before the clouds roll in, having lunch in nearby Caldeiras (Google Maps Location) and afterwards taking a bath to relax your muscles from the hike in the hot pools of Caldeira Velha. However, don't forget to book your entrance ticket at least the day before.

Location and Tips

Azores, Sao Miguel

Caldeira Velha in the centre of Sao Miguel is a Must-Visit place but needs a bit of planning before. I have to confess we passed by accident, and all tickets were sold out. A kind group from Lisbon had two tickets left, and we were able to join them. 

The jungel like rainforest
The lush vegetation like in New Zealand.

The geothermal pools became a popular destination for those seeking relief from various diseases, tourists from mainland Portugal, and visitors from all over the world. Many believed that the hot springs had the ability to cure everything from arthritis to respiratory problems. The water is iron-rich and may react to your jewellery and stain your swimwear.

The Interpretation Centre in the middle of the park provides information about all Azores Islands, how they were developed, and details how geothermal energy and steam are used to produce electricity. The exhibition is quite interesting all information is displayed in Portuguese and English.

For those who are thirsty and hungry after the visit, there is usually a food truck opposite the entrance.
