What to Know Before Visiting U.S. National Parks This Summer

"To manage heavy visitation, the park uses timed-entry reservations for peak periods, so planning ahead is important—slots may be released well in advance and can affect impromptu park-hopping. With reduced ranger and seasonal staff across parks, expect constrained visitor services and programing; research current hours and shuttle schedules, bring essentials, and aim for off-peak hours to avoid the worst congestion." - Stephanie Vermillion Stephanie Vermillion Stephanie Vermillion is a travel journalist and photographer covering culture and adventure for Travel + Leisure Outside, and more.
