We took a boat trip fron Alcudia port. It was lovely and went all along the coast. The cost was 21 euros which is a little over £15 and the trip lasted four and a half hours.
Apart from this, there is quite a few other boat trips from the port area.

Thanks for that bozzly, been waiting for an answer for ages, as were on a low budget this year I wanted an idea of what the cost would be. I really want to do the boat trip.

Tell us where you are staying and we might be able to help you.

Hi Pollensa,
Were staying in Cal'd'Or at the Cala Ferrera Hotel on the beach, any information on the area would be great, I have always wanted to go to Cal'd'Or, and am really looking forward to it.
Thanks in advance
Bobby

If you walk down to the harbour, there are all manner of boat trips to book from speed boat type ones up to glass bottom boats, we were there for the day 2 weeks ago. It is fantastic to sit at a restaurant eating your lunch and look at how the other half with their million pound boats live, enjoy your trip.
