Ventanilla
The beach is named after a formation that has shaped out a small window along the coast. The beach is very interesting because of the large amounts of minerals it's shores contain. The amount of minerals changes the sand to a metallic grey and heats it up another 20 degrees, so bring sandals. The beach, unlike the other towns, is not what actually brings tourists here. The real attraction is the wild life of it's mangroves. There are two types of tours available here. One is the government sanctioned group (recognizable by white t-shirts) that will take you to a small zoo and a mangrove tour for 100 MXN$. The other is a community organized group (in red t-shirts) that will take you only through the mangroves for 50 MXN$. I took the latter because I was told the zoo was nothing special. It includes a small orientation about the town and the beaches before heading out. The whole tour lasts about an hour and a half. The tour of the mangroves allows you to see crocodiles, fish, pelicans, swans, and iguanas as well as several unique plants. I recommend bringing a hat and sunscreen because it is not very shady and the sun can get uncomfortable. There are restaurants available here to go for lunch after.
