Gerard Acosta
Geologist by training, natural sciences teacher and nature and mountain guide. Passionate about the dissemination and interpretation of natural heritage, he has oriented his professional career towards bringing knowledge of the natural environment closer to all types of audiences. The curiosity to understand how nature works has led him to constantly observe, explore and learn from the environment that surrounds him and share his knowledge.
He sees education as a way to spark curiosity, encourage critical thinking, and build meaningful connections with the natural world. Through observation and hands-on experience, he aims to interpret the language of nature and make the processes, stories, and values hidden within landscapes more accessible. For him, learning is a continuous, shared journey, and he continues to grow every day through nature and through all those with whom he explores, observes, and enjoys it with.
His professional experience allows him to bring a practical and applied vision of natural sciences to training courses, as well as the interpretation of geological and natural heritage, the reading of the landscape and the planning and logistics of outdoor activities.
