I did take that walk and am glad I did. The port at cairns is beautiful with wonderful gardens and playgrounds for the kids. I haven't seen that at any USA ports. I had a nice walk along the wharf area and down the esplanade in town. There was a pool area in the middle of town and the locals were enjoying the water too cool off from the heat. I went wading. On my return to the ship, they greeted us with iced towels - it was heavenly! I was dripping with sweat, red in the face and overheated. Those towels provided wonderful relief. The heat took all my energy so I went to bed after dinner.
