The Best Time to Book a Camping Is Six Months in Advance
You probably know that you need to reserve a campsite if you want to visit a popular park or a specific location, especially during the summer season. You may not realize that you may be booking the site you want months in advance, whether you think your vacation plans will succeed or not.
Recreation.gov mentions that you can generally make reservations six months in advance of your visit, with the exception of Yosemite National Park, which accepts bookings at the windows due to high demand. So if you’re looking to hike to a popular destination or during a busy season (like July 4th or Labor Day weekend), book as soon as your booking opens. Sites like the previously mentioned Reserve America and old favorite FreeCampsites.net can help. You should still book as soon as possible, even if you don’t have details such as who you will go with and how long you will stay in the know because you will have months. sift through the details, otherwise it would be too late.
