Visitors to Yosemite National Park have criticised a change to its booking system, saying it has contributed to severe overcrowding. The complaints matter because crowd-management rules are intended to protect visitors’ experience, road access and the park’s natural environment during busy periods.

The supplied material identifies the change as “moronic” and describes crowds as “crushing”, but does not provide details of the revised policy, visitor figures or an official response. It therefore supports the broad account of visitor dissatisfaction but not more specific claims about causes or scale.
