We want everyone to have a safe and enjoyable holiday and recommend a certain level of fitness for multi-day or moderate to difficult hikes in the Countries, as many involve hiking at high altitudes and over steep terrain. A good level of fitness and endurance will help you enjoy the trek, and moving slowly and steadily will help you avoid altitude sickness. We therefore ask that you confirm when booking your trip that you are fit and able to fully participate in all elements of the trek.
