I never been there (I live in Los Angeles, United States) but my friend told me that it is amazing. They told me that there many mystic yogis. Some of them are 700 years old, and you'll see him just like a boy of 25 years. That impress me (many people from Western Country will believe this). Any way, the most important thing to go there is to associate with saintly persons to get transcendental knowledge. Like this verse in Srimad Bhagavatam explains: (10.84.13)
yasyätma-buddhih kunape tri-dhätuke
sva-dhih kalaträdiñu bhauma ijya-dhih
yat-tirtha-buddhih salile na karhicij
janesv abhijnesu sa eva go-kharah
yasya—whose; ätma—as his self; buddhih—idea; kuëape—in a corpselike body; tri-dhätuke—made of three basic elements; sva-as his own; dhéù—idea; kalatra-adisu—in wife and so on; bhaume—in earth; ijya—as worshipable; dhih—idea; yat—whose; tértha—as a place of pilgrimage; buddhih—idea; salile—in water; na karhicit—never; janesu—in men; abhijnesu—wise; sah—he; eva—indeed; gah—a cow; kharah—or an ***.
One who identifies his self as the inert body composed of mucus, bile and air, who assumes his wife and family are permanently his own, who thinks an earthen image or the land of his birth is worshipable, or who sees a place of pilgrimage as merely the water there, but who never identifies himself with, feels kinship with, worships or even visits those who are wise in spiritual truth—such a person is no better than a cow or an ***.
(This is Krishna's speaking, no me.)
