What you can expect

This is a typical itinerary for this product

Stop At: Gruta do Natal, Altares, 9700-000 Angra do Heroísmo, Portugal

It is a very extensive geological formation, resulting from the formation of a lava tube in the interior of the island, comprised in the Serra de Santa Bárbara e Mistérios Negros Natural Forest Reserve. It has ramifications in the form of different tunnels, formed by lava flows in different directions. One of its curiosities is the fact that it is located largely under a lagoon, Lagoa do Negro.

Duration: 25 minutes

Stop At: Furnas do Enxofre, Porto Judeu, Terceira Portugal

They are constituted in a fumarolic field, in other words, in an area that comprises several outlets of aggressive volcanic gases, at different temperatures, some quite high (about 95º C on the surface and about 130º C at half a metre in depth). Such degassings are essentially composed of carbon dioxide (c. 95%), hydrogen sulphide (c. 3%), sulfurous gas, hydrogen, nitrogen, methane and others, in very low proportions.

Duration: 15 minutes

Stop At: Algar do Carvao, Estrada Algar Do Carvao Centre of Island, Terceira Portugal

Included in the Caldeira Guilherme Moniz, an ancient dormant volcano, in this Algar visitors can descend to about 100 metres in depth, and observe stalactites unique in the world for their silicate characteristics, and an underground lagoon, with crystal clear waters. It is classified as a Regional Natural Monument.

Duration: 30 minutes
