Warning: yelp address is wrong. Takes you to a weird place that is definitely not the Bluffs.
Also tried the google maps address which takes you to a small park at the top of the bluffs. There's a nice view of Lake Ontario but not much else.
Take Brimley all the way south. Parking lot is at the very end.
Bluffs are decent. It doesn't take long to visit/ take pictures of the actual Bluffs though. But there are some walking paths there that are nice.
