Went on a hike in Uldum Kær, which is Denmark's largest non-tidal marsh, covering 1200 hectares — not huge but definitely big enough for anyone to get lost.

The area is rich with bird life and has Denmark's longets river the Gudenå running right through it.

From birders I know this place is even more interesting in the spring when the migrating birds return, so I will definitely be back to experience that.
