Placement of "off the beaten track" in context

Yes, you can.

"Off the beaten track" means out of the ordinary or unusual, but that's not its only meaning. It can also mean in a remote location, or somewhere that's out of the way or out of a central, popular or touristy area.

You can use it as an attributive adjective:

They found a quiet off-the-beaten-track resort.

Like what @J.R. commented, you'll need hyphens to make an adjective out of a phrase.

You can also use it as a predicative adjective:

The farmhouse we stayed in was completely off the beaten track.

It's often used for things and places, but it can also be used to talk about people:

What do they think of you being so far off the beaten track?
