Our regular readers will know we love nothing better than incorporating national parks into our family road trips, but certainly the humble national park trip can come with its challenges.
National parks have always been popular with US residents and international visitors alike but recent years have seen numbers swell at many locations to unsustainable levels.
Rather than deny entry to any of the country’s 63 national parks, a timed entry system was introduced by the National Parks Service in 2020 to stem the flow of traffic throughout the day at those receiving the highest visitor numbers.
Not only can the crowds have a devastating impact on the parks that are supposed to be protected, but they can also cause overcrowding in the surrounding towns that comply don’t have the infrastructure to support the number of visitors
Whilst many parks have already operated permits for camping and other activities within the park for many years, this timed entry system applies to simply enter the park or key roads, trails, or parking lots within the parks at peak times.
These timed systems will be continuing in 2023 with a small fee for the service, booked through recreation.gov. Here’s what you need to know and which national parks will be impacted in summer 2023.
Top Tip – You can register your account with recreation.gov in advance of reservations opening to save you time when you go to make your reservation.

Will More National Parks Be Added In The Future?
It’s interesting to note that only one of the top 10 most visited US National Park sites in 2021 is on this year’s list of National Parks requiring reservations in 2023.
Some of the country’s most popular parks, including Yellowstone, Grand Canyon, and the Great Smoky Mountains, are accessible without reservation.
This does not mean they will not require reservations in the future, nor that you may see significant congestion, lack of parking spaces, and tailbacks within the parks; if parking lots are full, rangers will close particular areas within the parks.
Information correct at the time of publication, last updated January 2023. Parks may put emergency measures in place or subsequently change their entry policy at any time, so always check information directly with NPS and recreation.gov before planning your national park visit to avoid disappointment.
