2. Botanical Gardens
The University of Copenhagen Botanical Garden was established in 1600, and moved to its current location in 1874. Its 10 hectares feature more than 13,000 species of plants from around the world, including many local Danish varieties. You can visit 27 historic glasshouse conservatories that display rhododendron gardens, cacti, Arctic plants and more. It’s a pleasant – and free – place to poke around for an afternoon in any season.
