Your best chance will probably be the Lake Louise Gondola. Other than that you might spot them on any road in the region, Bow Valley Parkway, Lake Moraine Road, Lake Minnewanka Snenic Drive. Out of Canmore the Smith Dorrien Trail. Best time will be either dusk or dawn.
The above is your best bet......
....or you could try hanging a large uncooked roast wrapped in raw salmon around your neck and go for a walk in the woods...
That would help........
Go camping. They find YOU.
Just kidding. To be honest, your odds are not great of seeing a bear on any given trip; they tend to stay away from areas popular with people; they like privacy.
But the Lake Louise gondola sounds like your best bet. It's above a ski hill, and apparently bears love to forage on ski runs in the summer, something about the vegetation. No promises, but you might be lucky there. :)
If it's bears you want to see head to Glacier NP in Montana. Chances of seeing bears mid August to late Sept at Many Glacier very good. They are often seen on hillsides and lake shores very close to the road
It would not be uncommon to see black bears along the highway. But grizzly bears tend to be in the high country and you would need to be hiking to find them and this means that you need to worry about safety. Most backcountry hikers take steps to avoid bears as they can be dangerous. Stop at a park visitor center. They will usually have a log of wildlife sightings. Based on your question, it is obvious that you are not experienced at travel in bear country. If you see a bear along the road, stay in your car.
Around Lake Louise, the alpine is usually not free of snow until the second week of July, give or take. Therefore, at the time you will be here, grizzlies will still be foraging in the lower meadows and avalanche runouts where the food sources are. As the vegetation and berries mature in later summer (August), they then start moving to higher ground. So your chances of catching a glimpse along the 1A, Trans-Canada, Smith-Dorrien, Minnewanka roads etc. are as good as anywhere, particularly at dawn or dusk. But it's a crapshoot of course. Like the last poster said, for the sake of everything holy and decent please help keep the bears from becoming habituated to humans and certainly stay inside your car :)
Any time I've run into a grizzly in the backcountry or while driving, it's been when I least expect it. I hope you see one, and have a good trip.
been to banff and jasper national parks probably...a hundred times. seen 3 - 5 bears. as suggested...if you really want to see a bear...be irresponsible...camp in the "out back" and leave food all over the place....but be prepared to get mauled. hope you see one at a safe distance.
No one seems to appreciate it when I point out that by far the most reliable place to find bears is the city dump....
Not here, at least not anymore. The dump, er, transfer station, is surrounded by an electric fence. Banff's too, I am sure. The goal is not to allow bears to become habituated, seeking food sources from humans.
