The Edmonton zoo is cute and sad all at the same time and world famous because all these celebs including Bob Barker (spay and neuter you pets) wants to save Lucy the Elephant! That's about the only reason to go and even then, you'll probably see her pound her head agains the huge metal doors and it will tear your heart out while watching the zoo keepers "trick" her into stopping that by giving her vegetable to eat. It's awful...she takes like a dozen steps back and litteraly runs into the doors... you can hear the "slam" just about anywhere in the zoo including the parking lot it's that loud. Wow, I'm depressed now I'm going to stop.
Calgary has a dinosaur park, brand spanking new penguin attraction 2012, lions, tigers lots of big cats, hippo, giraffe it's just an awesome place and well worth visiting several times.
Go first thing Sunday morning when they open (10am I think) and buy the lunch buffet/admission ticket. It seems a bit expensive but includes zoo admission and a breakfast/lunch buffet overlooking the giraffes = priceless! Oh, and this ain't no chines el cheapo buffet either, real bacon cooked right, eggs benny, yes eggs benny in a buffet, this is great suff that you should experience once in your life. It's been over 7 years since we did the giraffe buffet as the kids call it and we still talk about to this day telling anyone who will listen about how great that was.
You could in effect spend two full days at the zoo and not be bored.
