|Red line shows the route|
It is quite a tortuous route, with a few branches, so we loaded up an iPad with Google maps so we could follow our progress and check which branch of the channels to take. Following the tour boats does not always work as they often head off down the side channels.
|Lots of monkeys - even during the day|
At each end the channel is quite wide but in the middle it narrows and shallows. Apparently there used to be a tunnel at the narrowest point, but it is now a cutting.
