The green heart of Bonn is a park that runs along both sides of the Rhine. Covering an area of 160 hectares, it is almost as large as Bonn city centre. One of its major attractions is Auensee lake, where boats can be hired. The Japanese Garden, apiary, sensory garden and Rheinauensee lake are also very popular.Botanical gardens
Bonn University's botanical gardens behind Poppelsdorf Palace were created in the early 19th century, with greenhouses and open spaces replacing the royal gardens. Thanks to Bonn's mild Atlantic climate, around 3,000 species of plant from the earth's temperate latitudes thrive here. In total, more than 8,000 different plants are cultivated on the 6.5 hectare site.
