(CNNGo) -- It is the curse of every curious traveler -- you're walking through a new town and you can sense the history, you can smell the restaurant, you can hear the train you're meant to catch, but you have no idea how to get there or discover more.
Thank heavens for augmented reality.
Now, with apps that cost from nothing to a few bucks, you can lay digital worlds over the top of the real world through your phone's camera view. Suddenly data on hotels, restaurants, shop offers, landmarks, social gaming, even menu translations, is at your fingertips.
Here are 10 fantastic AR apps that every traveler should know about.

Platforms: iPhone 3.1+
Download link: itunes.apple.com

Would be great to see this extended to other cities.

While slower than Word Lens, it offers the capability to translate more languages.
