'highly attractive part' is the definition.
'ardennes' can be an answer for 'part' (I have seen 'part of France' mean 'ardennes' so perhaps 'part' could also mean 'ardennes'). I'm not sure about the 'highly attractive' bit.

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for ardennes that I've seen before include "Region of France/Belgium" , "battleground" , "Wooded region of south-east Belgium, extending into Luxembourg, France and Germany" , "Wooded area of northeast France" , "part of France" .)

I've seen this clue in The Globe and Mail.
