Absolutely the best thing I did in Ibiza. It cost me 40 euro, and it was just myself and the guide Yamila (hope I spelled that right!). I emailed them from their website, and asked a few questions. Yamila quickly replied in full and great detail! I did my booking and asked another question, and it was the same. Very informative and I was booked in, easy as that! The place would have been tough to find if it wasn't for her helpful directions! Anyway, once I was there I found out that it was family owned and run, and everyone there was beyond friendly. I gladly paid my 40 euros, and off we went! The best part was how I was literally the one in control. If you want to stop and swim or snorkel, you do it! It's all your call! Once we got to the underwater cave, my breath was gone. Such an amazing thing to do, and it was A pretty sketchy feeling being under there! Being a river kayaker myself, this was definitely a thrill of sea kayaking. We later stopped on a small but nice rock beach, and then snorkeled on the way back. I can't suggest this more highly, it exceeded my expectations, and I easily would have paid 80 euros for it! Very amazing 2 hours, thank you very much and best of luck to you!
