Hello Rasa, we regret your experience that was not carried out with our company (we already reported it to Viator to correct the location of this comment). We have been working with an expert tour operator for more than 20 years, for whom safety is their priority and if the weather or sea conditions are not correct, the tour will not operate, because the most important thing is that it be a pleasant experience. and safe for tourists. It is for this reason that we have excellent comments for more than 17 years of this tour that we offer, in addition to having certified bilingual naturalist guides. The beauty of taking this tour from Sierpe is that it gives you the opportunity to enjoy the river and the mangrove ecosystem, home to various seabirds, snakes, and crocodiles. From here the boat leaves towards the sea towards the Corcovado national park, San Pedrillo station, where the walks described in our tour will take place. I hope you have the next opportunity to do this tour with us and so you can enjoy this beautiful tour, ideal for nature lovers who have limited time to visit Corcovado Park.
