Nice region I found in such as Mississippi area (7)

I believe the answer is:

riviera

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

'area' is the definition.
(I have seen 'Coastal area ' mean 'riviera' so perhaps 'area' could also mean 'riviera')

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for riviera that I've seen before include "French Mediterranean holiday area" , "Med coastal region" , "Nice location" , "I arrive! (Anag)" , "Warm coastal district" .)

I've seen this clue in The Telegraph.
