The Greina Plateau lies between the cantons of Graubünden and Ticino. Even as early as the Roman era, important routes across the Alps led through this region. The plateau has remained an untouched jewel because it is still only reached on foot.
Even the ancient inhabitants of pile-dwellings chose Erlach on Lake Biel and St. Peter's Island as their abodes. The Romans too left traces. Bishops and members of the nobility ruled from here in the Middle Ages. Today both are popular destinations for nature lovers and visitors seeking rest and relaxation.
The mild climate at Lago Maggiore is unique in Switzerland, and enables subtropical plants to flourish in the open air on Isola Grande, the large island. The Botanical Gardens of the Canton of Ticino house around 1,700 plant species.
