Not really worth the money, as we didn't see much! - It was okay - we had to walk into a little cavern via a pipe/stony bottomed shore to get into the kayaks, everyone in the group had doubles, which are more stable. We went to a cave that you can see from the top vista of Riomaggiore, about a 10 min row away, it was very dark with some 'teeth' like shapes in the 'roof'. The offer to swim into the complete darkness to a beach was not appealing to anyone in the group! We then had two options, to row to Manarola for a view from the sea or to go more wild and paddle through a canyon. Nobody wanted to voice a selection and although one guide had said we could split the group to do both, we all ended up being taken to the canyon, but it was too choppy to go through it. We then paddled back towards Riomaggiore to go into a small 'beach' area to pull up the kayaks and stand around for 15 mins. It wasn't a beach, but there was a small rockpool with plantation and small fish. Found this part a little dull. Then back to Riomaggiore (we were practically already there), for photos and that was it! Didn't feel like in two hours we saw anything and we only paddled probably 400m max away from Riomaggiore. I think all-in-all at the £78 per person price, we would have been better hiring our own kayak and having the option to go where we wanted. I will add that I gave the 3 stars for the guides, who were very chatty and nice, it was still an ok activity for some exercise and meeting other tourists (French and American), just not worth that. Had it been £40/45 a person, I could have given it 4 stars.
