Puerto del Rosario

Puerto del Rosario is Fuerteventura's capital, so the carnival, which lasts for over 2 weeks each year, is usually attended mostly by residents and locals, not tourists.

Puerto del Rosario has been the capital of Fuerteventura since 1860 and it was previously called "Puerto de las cabras" (Port of the goats). The city is the largest on the island, with a population of around 30,000 people according to Wikipedia and it's the main port in Fuerteventura, with many big ships coming here every day.
