The entrance to Threave Estate is at the southern end of Castle Douglas just south of Carlingwark Loch and is easy to find. The Threave estate, owned by the National Trust for Scotland, has numerous public paths, by-passing the gardens. Park in the car-park at the gardens and follow the yellow arrow route markers. There are lots of choices to make during the route to extend the roate to take in other attractions and things of interest. The Walking Scotland Website has lots more information about what’s available.
