The Hortus Botanicus, a bite-size version of Kew Gardens, is one of the oldest botanic gardens in the world. Despite its small size, there are more than 6,000 plants growing in the garden and the greenhouses.
The highlight of the gardens is the collection of prehistoric cycads, some of which are up to 300 years old.
Unfortunately also preserved in the café is the traditional Dutch attitude to service. After sitting at a table for ten minutes we went up to the counter to make sure that we weren't meant to order there and were told that some one would come to serve us. After another quarter of an hour of being ignored, we walked out.
Worth a visit, but make sure you are not hungry or thirsty before you go.
