From small spaces in quiet locations to large holiday centers with fun for all the family, all the sites are professionally inspected on an annual basis for each edition of the guide. Top-rated sites receive the coveted gold pennant award and the best regional sites are highlighted in an annual awards ceremony. Glamping-only sites receive a green pennant award and are highlighted through the guide. For the guide's half-century celebration, there is a special feature on how camping has changed since ratings first began in the 1960s.
