Mt Wilson is a two hour drive from Sydney via Bell’s Line of Road, with the turnoff between Bell and Berambing, making a great day out. Extend your visit, make a weekend of it and visit the heritage brick Turkish Bath Museum with its arched windows of stained glass and Italianate decoration, take in scenic views from various lookouts, go walnut or chestnut picking, and for some adventure try canyoning.
I went to visit Breenhold Garden on last year Autumn Seasson. This year, I went to Mt.Wilson a little bit early in the mid April. Not all trees has change colour, however I managed to get a nice autumn picture at Sefton Cottage.
