Camp sites are getting expensive. Spend up to $50 a night and all you get are loud neighbors, a picnic bench, and a fire pit. Glamorous camping (aka glamping) might include cleaner bathroom facilities with flush toilets and hot showers, but the prices go up accordingly. Still, there are many campsites with cheap fees if you know where to look. Cheapism.com found beautiful and inexpensive sites across the country. And while you can always set up a tent in the wilderness and camp for free (check local laws first), the focus here is on tent camping at sites with toilets, potable water, and a maximum charge of $20 a night. Cheapism found private and public campgrounds by searching through the state and national parks websites, Recreation.gov, Yelp, FreeCampsites.net, TripAdvisor, and regionally-focused publications. We used these sources to gauge campgrounds' popularity and appeal by the number of positive reviews and mentions in "best of" camping lists.Prices at many campgrounds vary by season. The prices listed here pertain to the campsite before tax or fees; when stated as a range, they reflect seasonal changes. National and state parks usually impose additional entrance fees and may charge to reserve a site online; state parks may charge more for nonresidents. Annual passes for government-run parks can decrease the overall cost if you'll be camping several times during the year. There are also discounts available at most campsites for seniors, veterans, people with disabilities, AAA members, and members of camping-focused organizations.
