Downe Activity Centre is an 86-acre outdoor adventure site set among ancient woodland and grassland in Downe, near Orpington in the London Borough of Bromley — just 16 miles from central London.

Originally established as a Scout camp in 1929 and opened by Baden-Powell, the site has a rich history that includes use as a Home Guard training ground during World War II.

It is now operated by the Friends of Downe Activity Centre (FoDAC), a registered charity that purchased the site in 2024.

The grounds offer a mix of open grass fields and woodland campsites alongside indoor accommodation blocks with kitchen facilities and nearby toilet and shower blocks.

The centre welcomes Scout and Guide groups, school trips, Duke of Edinburgh expeditions, and family campers, with a growing range of outdoor activities on offer. It is accessible from Orpington and Chelsfield rail stations.
