I believe the answer is:

idyllic

I'm a little stuck... Click here to teach me more about this clue!

'picturesque' is the definition.
(I've seen this in another clue)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for idyllic that I've seen before include "Blissfully pastoral" , "Peaceful and happy, quite perfect" , "Heavenly" , "Delightful in every respect" , "Charming, picturesque" .)

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