Trekking difficulty depends on the specific route, and our treks typically involve multiple days of walking on rough terrain. Generally, the longer the trek and higher the altitude the tougher the trek will be. Other factors for assessment include terrain, amount of ascending and descending, expected climate. For treks listed as strenuous, it can be manageable if you are physically fit and have maintained a suitable level of activity up to the trek. We can also customise treks to try to best match your fitness concerns.
