The resident botanical gardens in Cádiz separates the old town and the sea, providing the air with a grace like only a verdant botanical garden can. This is the most extensive green part of the city and it shows, with a wide variety of flora offering plenty of breathing space for visitors in the height of summer. This is a truly international botanical garden, with trees from all over found within its trapezoid borders, and there are often interactive exhibits to keep the kids engaged during that much-needed walk. Oh, there’s also a lake with waterfalls, if you needed more reasons to visit.
