The clue is in the name. This is a unique botanical garden in Spanish terms, as it is filled with plants and trees from the Americas only, flora donated by countries from that most famous part of the planet. Completed in time for the 1992 expo, this garden runs alongside the tranquil Guadalquivir and is a great place for a run or a jog, or simply a spot in which to escape the frying heat of the summer months.
