Spend a few hours in the perfectly landscaped grounds of Botanical Gardens. Admire the wide range of plants, see if you can spot some birds or simply take off your shoes and enjoy the grass between your toes.
This showcase of plants is in Cayenne, a place that has lots going for it! Place des Palmistes, Montjoly Beach, and Musée Alexandre-Franconie are other good sightseeing choices nearby when you're done at Botanical Gardens.
