Kazinga Channel  
Queen Elizabeth National Park, Uganda

The Kazinga Channel slices through Queen Elizabeth National Park in Uganda and is a great place to see classic African wetland wildlife...

personal experience

I stayed in the Queen Elizabeth National Park for a week, and cruised the Kazinga Channel in October 2019.

While it might sound like something Sheldon from Big Bang Theory would say, the name Kazinga is used for a channel of flowing freshwater that connects and drains Lake George into Lake Edward. It is located in the northern section of Queen Elizabeth National Park. It is over 30 kilometres long. Several of the lodges in the national park and just outside it are alongside this waterway, including the Queen Elizabeth Bush Lodge and the Mweya Safari Lodge.  There are several different places from where cruises depart, including from the Bush Lodge/Community, and further down river at the Uganda Wildlife Authority (UWA) centre/Mweya Lodge.

Updates
Throughout the virus I am working in Australia on and off as local borders close, mostly in the Kimberley with Coral Expeditions (May-September). If you can't go travelling until everything settles down, then until then, here I am doing online guided walks for Noble Caledonia and online lectures for Silversea.
