I think doing something different, taking you out of your comfort zone and normal home comforts and being challenged a bit is great.
It was thoughtful thinking of those who did the trip without all the comforts we had like waterproof trousers and food etc… escapism, time to think, time to get to know people, time to get to know yourself and how you adapt to situations. It was very varied, each day was different, it was great being outside in nature away from everything!
