Mary River houseboats is one of the best things you can do in Darwin. See the wetlands, fish a little, crocs, birds, have a few drinks, it is fantastic. It is one of those trips that you always take visitors on but never gets old.
Make sure you don’t use any lights! Finish dinner and clean up well before sunset. Wetlands is another name for a swamp, getting every single mozzie and midgee in your boat is what will happen if you leave the light on.
Life is a bit easier if you have a small boat with it. Easy to tow, but you don’t have to worry about getting stuck against the wind, as you can just tow yourself out.
A single night really is enough to see everything, more is good, but it isn’t necessary.
