Since the start of the pandemic, more Americans have been sleeping under the stars than ever before. Much of that uptick comes from new campers: a 2020 report from Kampgrounds of America (KOA) found that 25 percent of campers last year had taken their first camping trip, and most said they plan to continue camping into 2021. All of which is to say: this summer is going to be a busy one at campgrounds. With many sites booked out months in advance, now is the time to start planning your getaway. “Many state parks open for reservations four to six months in advance, while most national parks open six months in advance,” says Ashleigh Rudolph, founder and lead trip planner of Pine Road Travel Co., an outfitter that plans custom RV and van trips. “Have these dates on your calendar, as the more popular campgrounds can sell out in seconds. For the campgrounds that don’t sell out the minute they go on sale, you’ll still want to grab the best site within the campground, and the only way to do that is to book early.”
