A long post, for which I am not sorry. I have found 'the official' website concerning the M.o.D. training areas around us. All the details are on https://www.gov.uk/guidance/defence-infrastructure-organisation-and-the-defence-training-estate but here are the salient bits for the three sites around us ...
Aldershot and Minley training areas are located to the west of Aldershot and north west of Farnborough in Hampshire.
Access opportunities Public access is permitted along all public rights of way within both training areas at all times. Open access on foot is allowed in areas within the managed access symbol on the Ordnance Survey Explorer maps. This access is subject to the terms and conditions of the Aldershot and district military byelaws which are displayed at the principal access points onto the training areas. Do not interrupt any military training activities and please observe the conditions of the byelaws all times.
For further information on access please contact the defence training estate training area Officer on 01483 798357.
Ash and Pirbright range danger areas are found to the east and north-east of Aldershot and Farnborough.
Pirbright range danger area is closed at all times with no permitted access, due to unexploded ordnance risk.
Ash range danger area is closed only when the red flags or red lamps are displayed. At all other times Ash range danger area is open to the public for access on foot. Access is subject to the terms and conditions of the Aldershot and district military byelaws which are displayed at all major access points onto the danger area.
For further information on access to the range danger area at Ash please contact the senior range officer on 01252 325233.
Hankley & Elstead Commons are located on the Longmoor training area which is situated on the boundary of Surrey and Hampshire between the towns of Bordon, Liphook, Farnham and Guildford.
Public access is permitted along public rights of way across both commons at all times. This includes two walks across the open heathland of Elstead and Royal commons. In addition open access on foot is available in those areas delineated by the managed access symbol on Ordnance Survey Explorer maps. When walking in the training area you are requested not to interrupt military training and to observe the byelaws.
For further information on access to the commons telephone 01420 483375.
