The Japanese Garden in Clingendael Park is open from 14 to 29 October this year from 10:00-16:00 every day. I went there today as the weather was amazingly warm for October to see the autumn colours in the garden. It was particularly busy as some of the Dutch schools and international schools are on holiday this week.
I must admit that although it was beautiful, I still prefer the Japanese Garden in the spring as it is even more stunning particularly with its beautiful azalea bushes. But it’s still worth visiting!
