Park in the disabled car park near the National Trust Longshaw Café / Shop. In front of the café a path leads to the estate.
After passing through a gate there are 2 options: a path leads down to a small, pretty lake where you can sit and enjoy the views. Alternatively, a favourite of Accessible Derbyshire is to take the path which goes straight ahead. This level path has great views and you can continue your walk until you eventually reach an inaccessible gate.
Return by the same route.
