How Parks Radar™ works

Parks Radar reads each park's sourced crowd, hours and live waits and rates each day by how busy it will be, relative to that park's own normal. Green is a comfortable day, yellow is busy, and red means near the park's capacity.

Ratings and hours are forecasts, not official figures. Always confirm on the official park site.
