My favourite place was a look out point after a steep incline, it offered spectacular views for miles. We hoped to see whales passing by but no such luck. We did see some eagles, deer and a couple of seals.
We took the entire day to do this drive, I would recommend planning for at least 4 or 5 ours so you don't have to rush. There are cute little galleries, cafe's and a few restaurants at certain points throughout the drive so you can stop for something to eat to break up the drive.
This area is by far one of my favourite things about Nova Scotia.
