Trompenburg Tuinen & Arboretum is a seven-hectare garden and arboretum in Kralingen, with carefully designed paths through collections of trees, shrubs, perennials, and bulbs. The site dates back to the 19th century and offers a quieter, greener side of Rotterdam.
It is a good stop for plant lovers or anyone looking for a calm walk away from the busier architecture and harbour sights.
