Before the opening of the campsite, scouts in Kowloon set up an unofficial campsite in Diamond Hill in the New Kowloon in 1940s. The campsite was proved to be too small when number of scouts increased rapidly. Another campsite of the association, Chaiwan campsite, by the transportation at that time was too far from Kowloon where is not a good choice for Scouts in Kowloon. In 1957, the Prince of Wales Banner Competition for Venture Scout was held between Mau Tso Ngam and Lo Shue Tin in Sha Tin. The Scouters found a good place for camping at the south of Mau Tso Ngam, open and with water nearby. They soon recommended it to the association and the association applied for the use of land through Tai Po District Office. In 1960 the land was granted by Hong Kong Government and the Gilwell campsite was established at that time. It takes three years to prepare the site for camping. Facilities for campfire and camping, and bridges were built. The Typhoon Mary of 1964 destroyed Golden Jubilee House. The house was rebuilt in 1968 and a ceremony was held on 23 November of the year. The first major camping event was a jamboree held in 1967 to celebrate 60 anniversary of the World Scout Movement. The summer of 1967 is also in the midst of 1967 riots in Hong Kong. At that time, the jamboree lasted for 5 days and 4 nights, with support from Hong Kong Government and Royal Hong Kong Jockey Club, inviting all Scouts in the territory and children from children's homes. The jamboree was deemed as a support for improving social services in government policy during the period of unrest. The camp site is likely named for Gilwell Park, a Scouting camp site in England.
Environment
430 metres above sea level, the land was granted by Hong Kong Government with an area of 200,000 square metres. The campsite is located in a valley between Tung Yeung Shan and Tate's Cairn. Several streams runs nearby. A road from Kowloon leads from Tate's Pass in the south which continues north to Mau Tso Ngam and Fu Yung Pei. The campsite is the only site in Hong Kong run by the Scout Association for wild camping only. Unlike other campsites managing by the Scout Association, the camp does not provide catering services. The site has only a few buildings for offices, lectures and activities.
