When the step-sons where here for the Australian school holidays we went to the Seoul Zoo. It's part of a huge sprawling complex that also includes a theme park and art museum, as well as parks, lakes, hills, hiking trails and, of course, hikers.
It was a gorgeous sunny day, and a weekend, and we were a bit taken aback by the mass of people (silly, I know). It was really, really packed. Which kind of added to the festive air and the Korean-ness of it all, but limited our actual ability to see any animals. Which probably wasn't a bad thing, as whilst a lot of the enclosures where quite large and appropriate, some of them were a bit depressing (seeing my favourite animal - the pygmy hippo - in a concrete bunker nearly broke my heart).
On the positive side the giant river otters looked happy and playful and super cute, and the lions had a big family unit and lots of space to roam about. Plus, there were awesome balloons everywhere, and a super long chairlift ride with fabulous views. Three stars.
