  • We recommend bringing water and sunscreen in summer, especially for children.
  • Remember to carry poles, which can be of great help in descents, stony or muddy areas and warm clothes and raincoat for higher altitudes. In the mountains, the weather can suddenly change abruptly.
  • Perhaps on this route you will find a mastiff dog protecting the livestock. These animals are working, so do not approach them to pet or feed them, nor allow them to follow you and leave their herd. They are NOT abandoned, they are simply doing their job. Avoid approaching livestock and in case cows, sheep or goats are interrupting the path, try to get as far away from them as possible.
