Anyone who lives in the Altitude 100 neighborhood knows or should know about it because Duden! It is large, quiet, with lots of levels, small and large clearings, trees in abundance, the beautiful castle Duden and in addition it is properly maintained.
The top is to go to enjoy the large clearing sloping side castle to rest a few moments in the sun, very often in calm.
The only two regrets I would have are the lack of water (it brings mosquitoes but also the freshness in summer ...) and the absence of flowers or shrubs with flowers.
