My partner and my son and I went on the Morning Cruise with Lake Argyle Cruises. I would highly recommend it!
This cruise is a beautiful way to see Lake Argyle. We saw rock wallabies, fresh water crocodiles and fed archer fish by hand. My partner and son had a swim in the lake too, at one of the deepest and bluest parts. It was just stunning (too cold for me though)!
Our guide was a fun, intelligent and articulate local/ owner of the cruise company. The coach and the cruising vessel were both in excellent condition and very comfortable. The tour was very well run.
We also hired a canoes for the three of us for half a day and enjoyed paddling about the lake and swimming at the bottom of a pontoon. It was just beautiful.
