Restorative and romantic, Copenhagen's Botanic Garden lays claim to the largest collection of living plants in Denmark. You can amble along tranquil trails punctuated with quotes from Danish poets and writers (in Danish), escape to warmer climes in the 19th-century Palmehus glasshouse and even pick up honey made using the garden's own bees at the gorgeous little gift shop.

At the garden's northwest corner lies the old-fashioned Geologisk Museum, worth a trip for its exhibition of botanical drawings and dazzling mineral displays.
