Asier Castro, Guide

asier.jpg

Im a 30 year old Spanish traveler, who’s been around the world for the last 5 years. The destiny made me crossed paths with diving and I have been in love with it ever since I saw a reef for the first time. I am very active, social and curious guy. Love meeting new people, taking pictures and sharing stories and knowledge with people from all around the world and my work lets me do day every day :) I got the chance to come to Iceland back in 2022 and Silfra caught a piece of my heart too, so here I am once again enjoying its clear water, intense blue and chilly temperature.
