Ventas Rumbas waterfall in Kuldīga is the widest waterfall in Europe.  To give an idea of its magnificence, there is a reason that no one calls Ventas Rumbas the horizontal Angel Falls.  Ventas Rumbas is quirky and pretty, but you are not going to be staring at it in awe when you have an awkward teenager nephew back home taller than the waterfall.

When I was in Latvia in 2016, I never imagined that Kuldīga would even be considered for the UNESCO world heritage designation, so the town was a mere brief stop on my way to another destination.  As such, I did not explore much of Kuldīga other than the waterfall and its immediate surroundings.  I can confirm that the immediate surroundings were just as idyllic and charming as the waterfall, but due to my limited experience of the town, my rating is based on the waterfall only.
