Preparations for a relaxing camping holiday usually begin by choosing a departure date. It is therefore useful to know when the entire family will be free. You can see below when school students in England have their holidays.
Each region or county has its own calender for school holidays. You can find out school term and holiday dates on schoolholidayseurope, the official government website for UK citizens.
Advice: always enquire at the school exactly when the holidays start and finish.
