September is probably the best month to see majestic humpback whales with their babies in the shallow waters of Bahía Ballena off the Pacific coast town of Uvita.
The festival hosts approximately 4,000 people for four days, with many staying on as tourists beyond the festival dates. While this provides an economic boost to the community, the people protesting against the festival see it as a threat to Costa Rican culture and a bad example for their kids.
