First of all, I had to wait an hour and a half in the morning, as a certain pick-up time was not communicated as agreed and there was no response to an email. I was alone. I don't know if that was the reason, but the guide was disinterested and was more on the phone than anything. He also didn't point out important things that you have to climb and wear good shoes when you go into the cave. Everything was more of a burden. The beach was more of a question: should we stop? with an undertone that I preferred to say no. The tour was then only three hours. I would have preferred to go on a cheaper group tour! Overall, the English of the guide was also difficult to understand.
