The journey ahead is an unforgettable adventure, taking you from the lush rainforest to the historic city of Cusco, and finally to the breathtaking Machu Picchu. However, I can’t help but worry about altitude sickness along the way. As a child, I frequently visited Yunnan, strolling through Dali and Lijiang without any issues.

But this time is different—I’ve never hiked at high altitudes or spent a night above 4,000 meters. Aside from considering Diamox as a preventive measure, what else should I prepare to ensure a smooth experience? I’ve already signed up for the Alpaca Inca Trail to Machu Picchu, a thrilling 4-day, 3-night expedition.
