Hi! Beaver are very resilient and so if the big floods did do some damage, they wouldn't have gone too far and are likely back already. Beaver are quite abundant in Alberta, even within the City limits of Calgary, but the trick is actually seeing them, as they are a bit shy and mainly nocturnal. Many of the City parks have thousands of trees that they have protected against beaver gnawing them down. The Inglewood Bird Sanctuary has them, and they are reviewed here on Tripadvisor. If you can connect with them by phone or email, they may give you some good suggestions as to where and when (likely VERY early a.m.) in Calgary, and other places you can spot them. Ditto any of the Kananaskis Info Centres, and Banff Park too. Cheers!

I would agree about 30 mins by the time you stop, listen to the birds & the river.

Yes few parking lots. Some are restricted to 2 hours. Parking are actually everywhere around. Have a nice trip!
