Edu
A free-spirited traveler born on the beautiful island of Mallorca three decades ago, Edu has always had an adventurous soul and an insatiable desire to explore the world. His passion for discovering new horizons led him to leave his homeland and embark on an unforgettable journey across Asia, taking him from the majestic peaks of the Himalayas in Nepal to the vibrant coral reefs of Indonesia.
The unexpected turn of a global pandemic brought him back home, but only temporarily. In 2020, with a backpack on his shoulder and diving gear in hand, he decided to follow his dreams once again. Fate led him to Cozumel, where he not only found the stunning coral formations of the Mexican Caribbean but also love and a place to put down roots.
A lover of nature in all its forms and the sea in particular, Edu lives his passion for diving as a true privilege. He enjoys sharing this magical experience with those who dare to explore the underwater world, passing on not just knowledge but also his love for this marvelous ecosystem.
For Edu, diving is not just a sport but a way of life that allows him to connect with the ocean and teach others about the beauty and richness hidden beneath the surface.
