"We booked a private boat tour in the morning. We would recommend this because there are much less people then than in the afternoon. Despite the fact that it is very hot (we were there in July), I would take a jacket, because it can get very cold.
The caves are really impressive and Gabriel and Mauro told a lot of history. They were also very humorous, we felt completely comfortable."
"We hired a kayak tour for two adults and two children and it was great. The very friendly workers and the monitor, a super pro paddle surfer, very nice and attentive, did not show the most hidden caves and coves. We were able to leave our things safe in their facilities and there is a very large car park at Castelo beach. . Of course to repeat... yes, next time at low tide!"
