City of flowers as they say .. opened b/w feb to may i believe ..
u need to go to Leiden Central Station from where you can take a bus to reach to keukenhoff ..
we visited the large flower park of keukenhoff .. heard that tulip fields around the park are in full bloom in march .. so i think one should visit this place in march .. anyways ..
ps – later i heard that Leiden University is a world famous university .. same goes for Utrecht University
