Meet us



Hello everyone! I am Alexander better known as Alexcinho, a happy member of Sustainable Lands and a passionate person about nature. Since I was a child sitting around the fire I felt this connection with nature and I have the best memories with my family and friends in a forest, river or somewhere in the mountains. Through life I had the chance to live in different countries where I discovered the richness of culture, traditions, languages and differences. I remember being in nature all my life, so for me the connection with your natural and social surroundings are the key for life. Because of that I have been following an educational path in Permaculture and Environmental Science that took me to live in ecovillages and work/volunteering in different projects around the world. For me life is an experience and as more feelings you experience as closest you are to a perfect day.

Profession: Environmental Engineer, Specialist in Environment and Sustainability, and Certified Permaculture Designer.

Passions: nature and dance. 

Life goal: share everything I can to create a better world.

Alsacia y Selva Negra – Tours, we are guides for hiking, trekking, cultural activities, city and also experts in topics such as permaculture and environmental sciences.
We are passionate about nature, the environment, history, culture and way of life in this part of Europe… and we love telling stories and very curious anecdotes 😉

Since 2017 we have been guiding groups, families, couples… through the city of Freiburg and through the forests and mountains of the Black Forest under the name “Aventura – Selva Negra”.
From this 2022 we will also do it in the beautiful French region of Alsace, that is why our new website and image is “Alsacia y Selva Negra – Tours”.

Do you dare to get lost with us in these spectacular landscapes? We wait for you! 😉

Alex and Fernando,
