Keukenhof in the Netherlands. I love the park, but it's an overcrowded flower zoo. It takes the most cliche aspects of Dutch culture and combines them with an overall perfect selfie experience. I doubt people are reading the names of the growers on the flower beds, going on the bicycle tour, and then appreciating the actual farms when they encounter them nearby.

It's contributing to the Disneyland effect ongoing in the area. Many people attending the park are incredibly inconsiderate and contribute to ongoing issues in the region. When renting bicycles, they're throwing themselves in front of cars and disobeying traffic laws. It causes drivers to develop a phobia of bicycles during flower season, and they'll erratically brake in dangerous situations. Traffic is a nightmare from the hoards of bicycles, pedestrians, and stopped cars, impeding the lives of local people.

The actual farms growing flowers for the park suffer from these visitors too. Visitors trespass on their land, cross-contaminating fields with their shoes, and carrying disease/pests between fields (or crushing flowers). Some of these pests are so bad, entire fields of flower bulbs need to be destroyed. At the end of the season, the farmers will simply destroy thousands of infested bulbs. The infected production field is then flooded for an extended period, making it unavailable for growing. When these farms no longer become profitable, they are being shut down and sold off for development into houses. It's hard to see as an tourist, but we are losing historical flower land and open countryside because of this nonsense.
