We'll never forget the incredible sights of fields of tulips and Europe's largest spring garden in full bloom. But also the sights and many different flavors of not just the Netherlands, but also next-door Belgium, from jaw-dropping Amsterdam to more off-the-beaten-path towns like Ghent and Antwerp in Belgium, to picturesque villages in the Dutch countryside.

It's not until you take a river cruise that you realize the perfect way to see the countryside is sailing through the heart of a destination on a river ship. On the Avalon Vista, floor-to-ceiling sliding glass doors facing your bed bring the outdoors to you, and early morning and daytime sailing means we enjoyed the journey as much as the destinations.
