We have to say that. Pilanita was not well prepared for the trekking. First did not have enough stamina and motivation (but we got a great supply of energy from big amount of food, ie. cookies, muesli, energetic bars, kit kats and by occasionally chats with people that were notoriously lying to us that its really close to the peak of the mountain). We have learned what NOT to wear on the trekking.
1)do not wear baggy trousers- its comfy in the city but too thin for cold night and high altitudes, also not the best idea for climbing the stairs...
2)do not take two pairs of socks.... you can do laundry everyday (so we did) but you will end up walking like a horse-clothes
3)do not take sticks found out in the forest- without a handle of professional walking sticks you can hurt your hands.
4)do not take summer thin sleeping bag or you will end up begging for 3 blankets and sleeping in winter outfit, ie. hats, gloves, woolen socks.
5)do not take the torch bought in 1 euro shop, its not strong enough... definitely not
But..we had great shoes:) don't forget to take that.
