You'll climb steep trails all the way to 4,200m in fantastic and diverse mountainous country. The trek takes you through lush cloud forest, green valleys and high passes with breathtaking views of snow-capped Andean peaks. You'll also have time to stop and explore fascinating Inca temples and settlements along the way.

Here at Macmillan we understand what it takes to train for and take on such a challenge. That's why we'll be there for you from the start with a dedicated overseas challenge team providing both fundraising and training advice. We'll prepare you for the challenge with our newsletters and briefing meeting, support you throughout the 10 day challenge, and be on hand to celebrate with you as you conquer this epic achievement.

By joining Macmillan, you will be helping us to provide immediate practical, emotional, medical and financial support that will change the lives of people living with cancer in the UK today. The challenge will be tough at times but you'll return with a real sense of pride in your achievement, and you'll have found yourself 60 new friends!

'This has to be the toughest, but most rewarding thing I've ever done. Beautiful country, friendly people, great company and a tremendous feeling of self achievement and all for a good cause! An experience I'll never forget.' Aileen, challenge participant
