The grounds of Soutomaior castle are among the finest gardens in Galicia, a region whose mild, wet climate produces conditions close to ideal for camellias and other acid-loving plants. Hundreds of camellia specimens grow throughout the terraced gardens, ranging from compact bushes to trees several metres tall, and the collection includes cultivars that are rare elsewhere in Europe. From January through March the colours are extraordinary — deep reds, pinks, and whites massed against the grey granite walls of the castle.
Beyond the camellias the gardens contain mature hydrangeas, banana palms, magnolias, and several enormous chestnut and oak trees that predate any formal planting scheme. Paths wind through the different levels, crossing small streams and passing mossy stone walls covered in ferns. The whole effect is lush and slightly wild in the best Galician tradition, as though the garden is in constant negotiation with the surrounding forest over who is in charge. Entry to the gardens is included with the castle ticket.
