Although a departure from a day outdoors to practice hiking, trekking, mountaineering, camping, etc. is not an issue scanning or much less, and by definition usually develop near the city, not be overlooked that some planning regarding equipment, first aid and supplies to be carried for the journey. This is equally true if we organize the tour we are (in a particular group) or we will be guided by a professional guide in the context of a group gathered through an agency or multisport adventure activities.
The first is to consider the material, equipment or equipment necessary to maintain security (protection against inclement weather, means of guidance and proper accident prevention activity) and provide first aid (primary healing of the injury or the most common injuries waiting for medical intervention).
You have to remember is that accidents happen everywhere, and although they are less likely to occur the less last march, and will be less severe in its consequences is the closer to a place where they can receive medical help , rescue or proper disposal, it is also true that the possibility of accidents is reduced even further if we care to eliminate as many risks as it is in our hands, and avoid all that we can not remove.
Thus, not only will reduce the possibility of accidents, but we will avoid wasting resources on mobilizing search and rescue operations to fix minor mishaps ourselves that had not been anticipated, may require outside help.
