When you go on trail, don't forget . . . . .
. . . and tell them where you are going, and when you planned to come back.
I mean, with someone who remains back home, friends who do not go hiking, or the owner of the apartment where you are staying, the supermarket owner, or possibly your travel agency host.
Do not go alone. Certainly not the more difficult tracks.
Take no risks. You are responsible for yourself and your partner.
