GEO Tour – Gruta do Natal, Furnas do Enxofre, and Algar do Carvão

Day 1: Gruta do Natal – Furnas do Enxofre – Algar do Carvão

Geo tour focuses on visiting three volcanic sites: Gruta do Natal, Furnas do Enxofre, and Algar do Carvão. Gruta do Natal consists of Lava Tubes in their natural state, and the visit involves walking inside these same tubes, and we have the opportunity to observe solidified lava in its most genuine state, as well as experiencing a truly different adventure. This visit is more physically demanding, and we do not advise clients who have back knee or claustrophobia problems.
Furnas do Enxofre is a fumarolic field, where we can observe sulfur, a volcanic gas, leaving the interior of the earth. This fumarolic field is directly related to the Pico Alto volcano, which still shows activity today, with sulfur being the physical expression of that same activity. In these Furnas food is not cooked, nor are there thermal baths, as they are dedicated to the appreciation of nature and the effect of sulfur on it. Algar do Carvão is the result of an eruption 2000 years ago when most of the lava it contained comes out and spreads over almost every island. As a result, the volcano is empty and, with several investments, also visitable, the visit is made on stairs, with the possibility of going down to the lowest point of the volcano. Throughout the visit, there are several levels, where the customer can choose to end their visit and return to the exit.

Note:

This is a cave tour that can only be done in the afternoon (02:00 PM) on select days in the winter (Tuesday, Wednesday, Friday, and Saturday) and all days of the summer.
