Northern Pakistan is very beautiful esp' Hunza Valley. Hunza is a place full of charm and I will never forget my wonderful experience there. We stayed in a lovely hotel, Darbar Hotel and they would serve you the biggest, juicest cherries in beautiful, handmade backets made from fresh leaves. There is a fairy-tale kind of place a 800 year old Baltit Fort to visit there as well, which is amazing. Its a Hunza landmark. Hunza people are so beautiful with soft pink complexion. I met so many who were older than 120 years! They will share their secrets of long life with you too including what their diet is and what they do everyday. They hide away from strangers though so you'll have to find someone local who can speak their lanuage and introduce you to their families.

It is said that cancer has not yet been invented in Hunza. And I believe it!

Muree is a great place to visit esp' during the winter months. Nathiagali is about 32 km from Muree. The bazaar there is amazing, you can find so many suveniors, girfts and handicrafts etc.
