Oh! I saw your photos Otro_Mas - they are incredible! I've been on the San Salvador three times so far, but always in summer. Why did you go there in April? You had no other choice or for the challenge?
I had a free few days and a looked for a short way to do in less than a week. As there is a lot of updated information on the web, I could decide quickly that it feets to me. A very good short experience.
