The guide was very enthusiastic and the caves themselves are very intersting. However, the location is very crowded during the tourist season and it is very touristy. The underground concert was cool, but the wait for the boat ride is lengthy and the actual time in the boat is very brief (and not worth it). Porto Cristo is very average and the beach you are taken too is very small and touristy. The pearl factory was somewhat interesting and brief. I enjoyed the caves and they are very unique, but afterwards I wished I had spent the day hiring a local boat and visiting some of the really pretty beaches on Mallorca.
