We arrived in Puntarenas, which is a working port with a not incredibly attractive central downtown. We signed up for a skybridge tour through the rainforest in Park National Carara. The park is in the transitional zone between the humid and dry forests which run from the mountains to the marshes and the sea. It was an hour plus drive to the park and along the way we stopped at the Rio Tackles Bridge to see the famed grey American crocodiles which can grow up to twenty feet. We saw a few but not the monsters. (We had better luck when we were here several years ago.) Our hike in the park was along a slippery trail and over 3 swinging bridges which would be rejected by a blind OSHA inspector. In the afternoon we visited Pura Vida Botanical Gardens and walked the trails with a knowledgeable guide explaining the flowers and fauna as well as protecting us from “army ants” a jumping and more virulent version of red fire ants.
