Discover the fascinating stories of life around Haarlem on this mill to mill boat trip along the Spaarne River. Starting in the city, you’ll pass by museums, castles, heritage buildings, and even a 16th-century weigh house that was an important part of the city’s beer-brewing history. You’ll then head up the river toward Heemstede past houseboats, stately homes, and green landscapes dotted with historic windmills.
