Are there free campsites in the UK?

Yes, there are free campsites in the UK, but they are limited and often referred to as "wild camping." Wild camping is the practice of setting up camp outside of designated campgrounds. While it's generally not allowed in England and Wales (except for some parts of Dartmoor National Park), wild camping is more accepted in Scotland, where the Land Reform Act (2003) permits camping on most unenclosed land.

Please note that wild camping should be done responsibly, following the principles of "Leave No Trace" and respecting landowners' rights. It's always best to seek permission from the landowner before setting up camp. Alternatively, consider staying at low-cost campsites or caravan parks for a more secure and legal option.
