A Day Out On the Mountain Range.

First you have to take a lot of drinking water and some food.
The second, take some winter clothes in case the weather changes, and very important, take a map with you if you don´t know the area.
When you have all these things in your bag, you can start your trekking on the mountain, much better if you go with some friends, but remember, when you return you have to take the rubbish with you.
It is also advisable to get a book with information about the route you are taking.
