Most bear watching vacations are in small groups, with expert guides and so they follow strict seasonal timetables.
If you don’t like the cold, then you might want to avoid polar bear watching in Churchill, Canada, in October/November. Temperatures can get as low as -30°C . July and August are much more popular, and it never gets too crowded up in these parts.
The early summer months of May and June are perfect polar bear viewing times in Svalbard, Norway.
Brook Falls, Alaska, is a top spot for seeing grizzlies grab salmon. As it is a US state, you might want to avoid the 4 July public vacation as it will pack out. However, the king salmon come here to spawn in late June and early July and coho salmon in late August and September. So, feast your eyes on the feast.
If you want to see female polar bears emerging from dens with their babies, March is the time, and Churchill the perfect place. But only if you book couple of years in advance.
For brown and black bears, summer is not always the best time for seeing them, as they can get very hot and go high in the hills to keep cool, making them hard to see.
In December, January and March, the bears like to sleep. Wouldn't we all?
