For a little light relaxation, or maybe a picnic after all the sightseeing, consider a visit to Munke Mose Park, which has pedal boats for hire during the summer.
This was once part of a factory grounds (Monks Mill), but was bought by the municipality in 1881 and eventually turned into a pleasant waterside recreation space.
There's a very popular playground, and in peak season, boats depart here for the zoo. Various festivals and celebrations take place in the park throughout the year.
