That trip I went with Paolo del' Agnolo (pictured above) who now works with Kayak-Ibiza based out of Es Figueral beach - but they drive the kayaks to the beach you set off from.
Last weekend the arrangements fell apart at the last minute & we couldn't do the trip planned because he got a large group booking the night before, so often the case in peak Season. It is incredibly frustrating being crowded out by numbers - trip I wanted to do isn't one you want to make with a large group including beginners. Not the first time and won't be the last.
However ..... instead I managed to organize a private 1 on 1 trip out with the infamous Martina Greef herself, who is amazing - both mad and hilarious. It was very special, we went from Cala Carbo out to Atlantis again but after stopping there went on further to the far beach at Cap des Jueu which is pretty much only accessible by Kayak, SUP or swimming. You enter through a tiny cave and it's unspoiled virgin Ibiza in the purest sense. The cliffs glisten with mud and it feels like you've reached the end of the earth. She doesn't accompany that many trips but fancied doing this one and conditions were good so it all worked out perfectly. Martina runs a network of guides too and is very good at pulling things together. WYSIWYG and she's very down to earth. Happy to give you her number if you want to arrange something nice next time.
