The long route is 17.5 miles and starts at the Lakeside Car Park in Studley Royal Deer Park which is pay and display £3 per car in 2012 but free to National Trust members. Shorter routes of 7.5 miles and 11.5 miles may be taken and it is possible to start the walk at other points.
Mark Reid (author of 'The Inn Way') has written an informative guide with a detailed and accurate description of the route of the Aislabie Walk together with an OS map. The guide is available free to download and copies can be picked up at pubs along the way.
The terrain consists of undulating paths and bridleways through woodland along river banks and through fields. The paths are occasionally muddy and you will have to cross many stiles along the way. There are some short stretches of road walking to link up the paths.
There is a limited bus service that goes close to the official start point but the most practical option is to travel by car. If you are coming to Studley by car make sure that you use the Lakeside Car Park as the main Fountains Abbey car park is locked fairly early in the day.
