I never though I was going to have so much fun doing camping and trekking for 4 days... But that's one of the most fantastic experience of my life ! It was fun, beautiful, the guides are incredible, funny and knowledgeable.
Yes, you suffer, but you don't think much about that when you have the best views ever and fun ! Still, I do think that you got to be able to adapt a bit (we wake up very early to start the trek and you may also spend a day under the rain) but if you keep smiling and be happy to be there then you'll have the time of your life !
