Good plans : - Find out about weather conditions before you leave. - Inform someone of your itinerary, as communication may be limited. - Make sure you leave in the morning, so as not to be caught unawares at night, and let someone know if you're going alone. - The routes you take are your own responsibility. - Choose an itinerary suited to your physical and technical ability. If in doubt, don't hesitate to contact mountain professionals. - Make sure you're properly equipped for safe hiking and weather conditions. - This hike is best done in summer, when there's no more snow.
