America’s national parks have seen a surge in popularity, with several parks regularly welcoming millions of visitors a year. The crowds are a sign of how beloved these places are — but they also create challenges that are reshaping how people visit.
The Rise in Visitation
Iconic parks such as Zion, Arches, Yosemite, Glacier and Great Smoky Mountains have experienced heavy demand, especially during peak summer and holiday periods. Popular trailheads and scenic drives can reach capacity early in the day, leading to long lines and crowded conditions.
Timed-Entry and Reservation Systems
To manage the crowds, a number of parks have introduced timed-entry or vehicle reservation systems during their busiest seasons. These require visitors to book an entry window in advance, helping spread out arrivals and protect both the visitor experience and the landscape. Systems vary by park and can change year to year, so checking the official park website before a trip is essential.
Other Strategies
- Shuttle systems reduce traffic in busy corridors, as at Zion and parts of the Grand Canyon.
- Parking tags and permits are required at some parks and popular trails.
- Encouraging off-peak visits helps balance demand across seasons and times of day.
Tips for Visiting Popular Parks
- Reserve early. Entry permits and campsites can book out weeks or months ahead.
- Arrive at dawn or visit late in the day to avoid the busiest hours.
- Consider shoulder seasons like spring and fall for thinner crowds.
- Explore lesser-known parks — many offer stunning scenery with a fraction of the visitors.
Protecting the Parks
Heavy use puts pressure on trails, wildlife and facilities. Following Leave No Trace principles, staying on trails and respecting closures all help preserve these places for the future.
With a little planning and flexibility, visitors can still enjoy the parks’ wonders while helping protect them for generations to come.
