UPDATED 03/04/2017: Gran Canaria in April smells of sweat and cheese (and sunscreen, of course) thanks to the Guia cheese festival and the Mogán triathlon. You can also visit a couple of local fiestas close to the resorts.
Gran Canaria is an island that knows how to party. And it does so in its own way. Rather than the dance music parties of the Balearics or the bull fests of Spain, Gran Canaria goes local with its fiestas.
The Catholic church rather than the local tourist authorities still decides when to open church doors in Gran Canaria. This means that some of the island's prettiest churches, such as the Puerto de las Nieves hermitage, are often closed during the day.
