Aspley Woods, which lies between Woburn Sands, Bow Brickhill and Aspley Guise, is privately owned by The Bedford Estates which allows public access only via a network of permissive paths, in addition to public rights of way and bridleways which cross the land. The Greensand Trust manages an Access Agreement between Bedford Estates, Milton Keynes Council and Central Bedfordshire Council which allows members of the public access to Permissive Paths across private land they would otherwise not be allowed to use.

The Bedford Estates has recently requested the implementation of a Dogs on Lead policy, in line with the rest of the estate, to enable all users of the woods to enjoy the area safely following a number of incidents reported at the site. The Users Group for the site and the Access Agreement partners were involved in this process, and signage communicating this, alongside guidance for all other users, is being erected at site entrances.

These measures are also intended to protect wildlife on the 326ha site which has areas of semi-ancient natural woodland, a Scheduled Ancient Monument at Danesborough Hill and Wavendon Ponds Site of Special Scientific Interest (SSSI).

Dog walkers should ensure that their dogs are on a lead and that they are in full control of them at all times. By doing this dogs will no longer be able to stray from the permissive paths and are less likely to be involved in incidents involving other visitors and dogs or disturb wildlife. 

The Greensand Trust manages public access to the site and administers a permit scheme for cyclists and horse riders - The Greensand Pass protects both the user and landowner against third-party liability and helps to fund the maintenance and safety checks of these paths by its rangers.

Central Bedfordshire Council Dog Control Orders operate at areas within this site applying to dog fouling and dogs on a lead by direction as applied across all Central Bedfordshire managed sites.
