Many trekkers ask whether they should take a porter or can they do on their own? If you are confident in your abilities, you have a lot of trekking experience and you know for sure that you will pass this route with a load of 13-16 kg, then you can not take it. If you can not, we strongly recommend taking Porter!
Although ofcourse for many people such weight will not become a problem, still it is better not to risk if you are not sure. Usually, in groups we take one porter for two people, each giving him 10 kg.
