of the programme specifically focuses on adventurous activities with hiking, rock climbing, kayaking, sailing, caving and shooting proving popular with units. Many Explorer Scouts can become quite proficient in their chosen activities, and some attain instructor's qualifications as recognised by the activity's national governing body (for example, BCU coaches for kayaking) as part of the Scouts adventurous activity permit scheme. There are a number of national and international events open to Explorer Scouts in addition to project and events held at more local levels. Examples of prominent events that have taken place in the past include the Sun Run, a weekend of activities culminating in night hike through the surrounding hillsides starting with participants watching the sun set and High Adventure, an orienteering event in a location unknown to the participants before the start of the event and incorporating a wild camp. In addition to events, community based projects are also run. One such example is the Epping Forest Scout Conservation Project, which ran between 1989 and 2015, as a residential experience looking at conservation and forestry techniques that linked to the section's top awards. World Scout Jamboree The World Scout Jamboree takes place every four years in countries across the world and is a wide-scale gathering of Scouts. The UK sends approximately 4,000 young people aged 14 to 17 from across the country, split into some 40 units with their own leaders and branding. Preparation and fundraising for a World Scout Jamboree takes many years and so older Scouts who would be Explorers by the time of the Jamboree often work in their troops to help fundraise for the trip to the jamboree. The purpose of the event is to take part in activities with Scouts from across the world with some 45,000 scouts from 152 countries at the most recent 24th World Scout Jamboree at the Summit Bechtel Reserve, United States. Scout Association events The Scout Association, through their Scout Adventures subsidiary, run a number of national events for members of the Explorer Scout section. These are centred on the nationally owned scout centres such as Gilwell Park. Gilwell 24 is an annual event that takes place at the home of UK Scouting, Gilwell Park, North London. It comprises a set of activities and challenges over a 24-hour period for some 5,000 Explorer Scouts and Rangers. It is often used as an event to mark occasions within the
