Agder Natural History Museum & Botanic Gardens Kristiansand

The winding paths through the established 50-hectare park at Gimle Estate lead through a botanic garden that also contains rocks, minerals, stuffed animals and greenhouses containing the largest collection of cacti in Norway. The estate house has 19th-century period interiors and extraordinary teethlike columns at the front, and there's also a historic rose garden dating from 1850. It's just over 1km from the centre, across the Oddernes bridge.
