As for the weather, don’t be fooled by the forecasts, it is always a hot and sunny tropical environment that defines what the Caribbean is all about. The tourist high seasons (mid-June to mid-July, and mid-December to mid-March) coincide with the windy months, but many folks share a well-kept secret: the low seasons are actually even better, because it rains sporadically, there are less people in the city, and the prices for everything drop. Cartagena is a port city on Colombia’s Caribbean coast. By the sea is the walled Old Town, founded in the 16th century, with squares, cobblestone streets and colorful colonial buildings. With a tropical climate, the city is also a popular beach destination. Reachable by boat are Isla de Barú, with white-sand beaches and palm trees, and the Islas del Rosario, known for their coral reefs.
