besides at the K-Gardens, where are the next best places to watch the parade?
The floats are good fun to walk around after the parade when they are parked in Haarlem.
I've enjoyed watching them pass in Hillegom and in Heemstede. Just find a nice place on the side of the road and do what everybody else is doing.
If you watch at the Gardens, which I hear comes through around 3:30, is it possible to travel the road to Haarlem after that?
There is a multilingual - including English in third - map available at the bloemen corso website. The map is at http://bloemencorso-bollenstreek.nl/media/10032/BCB2014-publieksfolder-web.pdf which will show you a number of routes to Haarlem. If you try to follow the parade you will go at a walking pace or slower.
Have a read of the bloemen corso program - English at http://bloemencorso-bollenstreek.nl/en/ - which is very informative.
I appreciate your advice and websites here. I think we will get to the gardens by noon and then be there for the parade at 3:30. Then we can find the small roads to get to Haarlem, explore the town and wait for the floats to end there. How does that sound?
Thank you!
