Even though the food is the most important thing on such a trip, I think one should also prepare for not getting into risky situations. A proper equipment is really worth the while. First aid and a compass are equally important in case of emergencies. There are actually a few watch brands which offer a range of models able to fulfill the purpose of a compass very well. Most of them are quite simple in their usage and as they are worn like wristwatches, they do not obstruct the wearer in any way.
