Anyone who visits the mausloeum fells dwarfed by the magnificence of the building and the atmoshpere of spirituality which pervades the structure. When I visited the site entrance was free.If you are in the city of Turkestan you will not have problem finding the mausoleum ,because all taxi drivers, actually everyone knows where it is.Once you are there, you should defninitely go inside and visit all the chambers including the burial-vault, which is preceded by wonderfully carved doors. Be sure to visit the chamber with a well. Khoja Ahmed Yasawi spent last years of his life in this well, because he didn't want to live longer than the Prophet.
