My friend visited this garden during autumn last year. It was pretty, but quite windy too. It's because the location is next to the sea. That's why it is quite windy.
Might as well come a little bit more prepared next time!
When you go see these flowers in April or May, when they are in full bloom you will be surrounded by millions of tiny little blue and purplish Nemophila flowers that are almost reflecting the sky above you. The park itself was already really nice, but the high light itself was definitely at the end were we could see the fields. I loved the fresh air since it was close to sea and there were a few really nice spots to take pictures and enjoy the view. The only down point is that there were quite a lot of people. But nevertheless it was a wonderful experience.
