Allotment sites are worth a visit. Here some examples.
The German Allotment Gardens
Allotment association "Wühlmäuse 2000", Landesbund der Gartenfreunde in Hamburg
Young allotment site with park character. It invites for a walk, offers   richly structured gardens as well as fruit to be tasted on its public   areas. The association works in an ecological way and is an example for   water management, stimulation of useful animals and protection of   species. It has a flower meadow for bees and insects.

Allotment association "Bachespe", Landesverband Berlin der Gartenfreunde
Dynamic association with a strong social engagement and a tight   cooperation with the Kita „Moosmutzel“. It is a site with only few   fences, low hedges and grassed paths. Also, people living nearby love   and care are very welcome for walks and a stopover in a green   surrounding. Educational paths built with love and care, are easy to   understand and are constantly broadened with new ideas.

Allotment site "Licht-Luft", Landesverband Rheinland-Pfalz der Kleingärtner
The association is characterised by its engagement for young and old.   With the school programme “Young people help the elderly and learn at   the same time” pupils meet elderly people and they both benefit from   their respective knowledge and skills. The programmes organised during   children’s holidays offer exciting activities in the garden for small   children and during the afternoons for the elderly the latter can   socialise. The excess of fruit and vegetables are given to the food   bank, which distributes this food to people in need.

Allotment site "Ulmenweg", Landesverband der Gartenfreunde Sachsen-Anhalt
By stimulating the offspring, child care and extensive specialised   advice in gardening matters, the association cares for its members in an   exceptionally good manner. It cooperates with the home in Merseburg   hosting several generations. Here live together – similarly to the   allotment association – people from all stages of life, starting with   babies up to very old people. They all benefit from the each other. With   this concept the association has been successful in dramatically   reducing the average age of its members.

Allotment association "Südhang", Landesverband Sachsen der Kleingärtner
The association especially cares for children, above all with its   innovative project „Schrebino-Kinderland“. The association offers a   generous allotment area to two Kitas in order to be used as educational   and information garden. The cooperation between tenants, children,   parents and educators is characterised by a relaxed being together and   is exemplary.
