Optimise drying during the night
If you have spent the whole day hiking in the rain and are base camping, i.e. day hiking and returning to the same base camp every evening, remember to dry your clothing during the day for the next day. Even if your first reaction is to attend to basic needs such as eating or resting, take a few minutes to hang up your clothing or lay it out in a place that is sheltered from any overnight downpours.~
If you have the misfortune to get the inside of your boots wet, take the insoles out, loosen the laces and, above all, do not place them too close to a heat source, as this makes them lose their shape so that you end up with sore feet the next day!
The added extra: you can also make the most of any sunny spells during the day to dry your things by hanging them from your bag (which has been dried itself) or on a tree during a break. Make the most of every ray of sunshine.
Safety advice: Experiencing a shower during a hike is one thing, hiking in driving rain with no visibility is another.~
We strongly recommend that you do not leave if the conditions of visibility are sub-optimal. ~
And of course, even though it doesn't protect you from the rain, remember to take one or more torches that can be fastened to the head or other elements so that you can be seen, even from a distance.
