If you have some spare time, the Dorset Scenic Lookout Trail is well worth the drive. Although I have not walked the trail myself, I have most definitely visited the top of the Dorset Fire Tower for one of the most amazing views available.
If you can conquer your fear of heights (the tower stands at 30 m high), there's nothing like being able to stand at the top of the fire tower, in the open air looking over the tops of the trees at the view over Lake of Bays.
The absolute best time to go is during the fall of the year as the leaves change colours - what a kaleidoscope of beauty to behold.
