Measuring time during treks is important. The Cuban nature is able to incorporate us among its attractions and track of time could be lost. It is important to wear a wrist watch because if we want to return to some place to rest it is not recommendable to do it at night because it can be dangerous, besides not having the day light if you had already planned another important activity. 

There are different kinds of watches but the important thing is not to forget bringing it, in order to know how to administer time well and prevent the facing of an unexpected event during our trekking and taking in mind the measuring of the events experienced, such as trekking duration as to evaluate return time and not letting the night to take us by surprise through unknown paths. The sky and the sun light can be the best clock if we know how to manage it correctly.
