Camping in the United States continues to surge in popularity, and as more families, couples, and solo travelers head outdoors, certain campgrounds are seeing record‑breaking demand.

In this guide, I’m breaking down the 13 campgrounds that are consistently packed year after year, why they’re so popular, what to expect, and bonus tips for how to secure a spot even during busy periods.
