Fodor's Expert Review Isola Madre

All of this Borromean island is a botanical garden, with a season that stretches from late March to late October due to the climatic protection of the mighty Alps and the tepid waters of Lake Maggiore. The cacti and palm trees here, so far north and so near the border with Switzerland, are a beautiful surprise. Two special times to visit are April, for the camellias, and May, for azaleas and rhododendrons. Also on the island is a 16th-century palazzo, where the Borromeo family still lives for part of the year.
