In the past there was on the today´s Spa Island a riparian woodland, mainly with the willow-trees and the poplars. A lot of the small lakes and a water-logged soil considerably make more difficult a movement on the island. Anyway, it was a natural area rich on a flora and a fauna. The remains of these biotopes are situated along the Slňava lake. With a drainage of the Spa Island before more than 200 years were the conditions in a nature changed. Instead of the plants preferred a humidity were used by a rebuilding of the Spa Park mainly the xerophily plants, whereby a local climate and the soil conditions were considered. The gardeners of Earl Erdödy naturalized here the trees and the bushes from all over the world, mainly from eastern Asia and North America, so that nowadays the exotic plants create about 80 percent of all sorts on the Spa Island. The oldest trees in the Spa Park are about 150 years old. A lot of the trees and the bushes beautify the Spa Island all the year and make the convenient conditions for a comfortable and relaxing spa stay.
A barycentre of the Spa Island is more than 100 years ago created a main alley with the pyramid poplars. It leads from the Colonnade Bridge along all the Spa Island to a golf course and was created in the north-eastern direction to be the medieval castle ruin Tematín seen on a horizon – on the top of the Inovec mountains.
