A cool spring enabled the flowers to bloom for the complete eight weeks that the gardens are open, organisers of the annual event said.
The large number of visitors was the result of the publicity around a Van Gogh theme and the increasing popularity of Keukenhof among American, German and Chinese visitors, and other visitors from South-East Asia.
The average age of the visitors was noticeably lower than in previous years. More Dutch families have visited Keukenhof this year thanks to new events and extra children's activities.
In 2015 Keukenhof, with partner Arriva, transported more than 200.000 visitors by public transport. An increase of 20%.
The Keukenhof theme for 2016 is 'The Golden Age'. Keukenhof 2016 is open from 24 March up to and including 16 May.
