King's Day - Amsterdam
The Netherlands' national celebration turns central Amsterdam into one continuous street party, with huge crowds pressed along narrow streets beside open water.
Why the crowd presents risks
- •Narrow streets beside open canals — limited escape and a fall risk at the edges.
- •City-wide density with people funnelling across a few bridges.
- •All-day alcohol and very high footfall.

Working this event?
Stewards and volunteers at events of this scale benefit from basic crowd safety training — learning density thresholds, route clearance, and emergency protocols.
These are our own event profiles, compiled from public information. We are not affiliated with, nor do we endorse, these events. Attendance figures are planning estimates, and the recommended number of trained crowd-safety volunteers is a rough guide based on common steward ratios — not an official figure or a legal requirement.
