Full Day
São Miguel


You can imagine yourself floating in the waters of the Atlantic Ocean. Swimming with dolphins is a unique moment. They are social animals and they usually like to play, even though they are wild. Join us for this wildly authentic experience where you will be joining the dolphins in their natural environment. You will see, listen and feel their presence around you.

Before we begin our tour our marine biologist experts will explain you some rules you need to take into consideration for you to be able to enjoy this moment. The snorkel mask instructions, the moment you enter the water and other safety instructions will be explained in detail. This experience is done on our zodiac boats and in groups of around 8 people. Two people will go in the water at a time.

Swimming with dolphins is usually a 2.5 hours activity, so after the tour, you will eat on a local restaurant in the marina and at the end of the meal, you will be ready to continue this adventure in a jeep! 

We will be heading to the natural reserve of Lagoa do Fogo in Ribeira Grande. Lagoa do Fogo is one of the most astonishing lakes of São Miguel Island. Just take your time, and enjoy the views!

We will stop along the afternoon in several key points for you to be able to enjoy the views and breathe in the nature surrounding the lake. The water is crystal clear down there and is located under a sleeping volcano that was formed more than 15.000 years ago.

To finish your tour with your heart full we will be visiting Caldeira Velha. This is a classified natural monument.  You will find a beautiful waterfall where you can bathe in with hot thermal waters that are around 25ºC. Caldeira Velha is considered by most people a spa surrounded by nature. A must do while in São Miguel!
