You could give an entire day to these beautiful botanical gardens a little outside Merano. Exotic cacti and palms, fruit trees and vines, beds of lilies, irises and tulips all cascade down the hillside surrounding a mid-19th-century castle where Sissi – Empress Elisabeth – spent the odd summer. Inside, Touriseum charts two centuries of travel in the region, exploring the changing nature of our yearning for the mountains. There's a restaurant and a cafe by the lily pond.
