Greg is a fantastic guide! He knows the Pyrenees as the palm of his hand and is extremely fit. He worries about the safety and well-being of people around, and pays attention to "little" things - checking if you are having a good time, putting sun protection or drinking enough water. He thinks of everything we may need for the hike and, if you want, he will give you little tips on how to read the terrain. Not even in the Himalayas I have seen someone so passionate and knowledgeable about mountains. Best of all, he can make you laugh when you least expect. If you love nature, it's guaranteed fun! :-)
