I├óΓé¼Γäóm assuming you came to find out where the Hidden Tower is. To go to the Hidden Tower, go to Faerieland, then head to Faerie City. You’ll see a big building or castle. The link is located at the upper-left of the castle. The image below will show you where the Hidden Tower is.
Here you can take your Neopet, Neopets, to go visit and browse through some of the most expensive items in all of Neopia. It is much cheaper to buy HT items off the Auctions or Trades than from the Hidden Tower. If I ever go there it├óΓé¼Γäós just to look at the items.
You can also click this link to go there directly.
