A beautiful and huge park in central Munich. Best reached via Odeonsplatz station, then walk through the Residence park.
We went twice during our stay- once in the afternoon and once in the evening. Both times it was buzzing with tourists and locals. Being English, I found it weird how much the layout reminded me of home! We sat on picnic benches at the smaller beer garden by the water and watched the ducks, with beer and excellent food- it is quite expensive to eat here but really you can have one dish between two. The BBQ ribs are amazing.
On our second visit we went to the larger beer garden by the pagoda- this is a lot more German, with the band playing. Beware of the wasps.
Other than the beer gardens, you can just sit on the grass and enjoy the atmosphere, or maybe watch the surfers!
