The gardens, shaded by bamboo and blooming with bougainvillea, ginger and other flowers, ferns and trees create a tropical oasis. Fed by the nearby sulphur springs, the cascading waterfall is a garden highlight. The mineral baths, also fed by the sulphur springs, were first built in 1785 for the French troops. Unless you really want to soak, skip the extra fee required for a dip in the outdoor pools, and spend more time in the garden.
