No you don't have to jump at all only if you want. Everyone gets back out just beside it. The junpnisnt that high either.

We had a pretty large group 20-25 people?) and all fit inside and had enough room to swim around. It is pretty dark and you do enter through an opening in the rocks and go through a little corridor that seemed to bother some a little but this is pretty brief. You can watch other people go in and decide not to do that part or if you get inside and find it isn’t for you the guides are very accommodating and will show you the way out. Have fun!

Hi jresca, I'm only just seeing this now - we were picked up in Muro so I cannot tell you where the meeting point is in Alcudia. However, the team that run this are extremely helpful so I would recommend emailing them or you can WhatsApp them via the number on their website. We found it a really fun thing to do as a family, and because it was only a few hours in the morning, no-one got bored or tired, and we thought it was really brilliant value for money!!

I'm guessing you can, but the day we went, it was fully booked up, so maybe it would be better booking as soon as you can to make sure you get a place.
