The first part of the journey was pleasant enough. The alpine meadows were delightful and the conversation was playful. The switch back trail was a bit more of a challenge as our calf muscles began to feel the strain. But when we reached the cliffs, I wondered if we were up to the challenge. Before us lay a series of cliffs into which the Swiss had embedded a series of wooden ladders. My fear of heights began to surface. But I was determined to give the first cliff a try. So one by one we began to climb.
