Hiking boots, should be in good condition and waterproof
Rubber boots (toilet walk is 800m each way and we prefer staying dry on our feet, grass is always wet. Many people wear wellington boots for the entire trip as the ground can stay wet, so bring boots that are comfortable. Also useful for getting in and out of the zodiac, and for crossing streams)

Water bottle, like the 500cl plastic bottle or something
Battery alarm clock
Other stuff you might like to bring:
Bear in mind that there are no electric charging points at Hornvik. Therefore, you need to avoid electrical items, i.e. bring book instead of electronic reader, a manual toothbrush rather than an electric one, a battery-powered alarm clock rather than a phone, sufficient spare batteries for cameras etc.
