You can enjoy watching the birds as they gather to rest along the Okavango river (these white herons were on Angola's side), or try to spot the occasional crocodile snoozing on the river bank...
Mokoro or canoe(s), whichever you c hoose is great for cruising along the Okavango River and enjoying the scenery. There's a lot of life along the river. The locals use it for many things, including bathing, doing their laundry, and washing their cars.
