These are entrance tickets for El Rosario monarch sanctuary. How much does it cost to visit? The prices are given in Mexican pesos. Check the exchange rate online and convert to dollars. Compare to the cost of a movie. Ticket sales are an example of ecotourism. The income can help protect monarchs by providing jobs for local people.
