Flora and Fauna of Saint-Malo
The mild maritime climate, strongly influenced by the Gulf Stream, results in lush and diverse vegetation in Saint-Malo and its surroundings. Visitors often notice an abundance of flowers adorning the city’s houses and streets. You can enjoy the blooming hydrangea garden and admire the beautifully arranged flowerbeds in Saint-Malo’s squares.
The wildlife of Saint-Malo is quite similar to that of the rest of Brittany. Wild rabbits can be seen on the outskirts of villages, and foxes, hoopoes, and herons are occasionally spotted as well.
The marine life of the Atlantic Ocean is remarkably rich. Commercial fishing includes flounder, herring, shellfish, shrimp, and lobsters.
