Tours are different. I indicated load in the table on a scale of 1 to 3.
The trips involves lots of walking around, going upwards and downwards. Nevertheless, it's not a classic camping hike – all the trips are radial, one and rarely two days long. You will not have a heavy backpack encumbering you – only the most necessary things: food, water, camera/phone and personal belongings.
Anyway, physical fitness is welcome, but I'll tune the complexity and intensity of our route to fit the group.
