Cold beach, popular with an eccentric (14)

I believe the answer is:

unapproachable

'cold' is the definition.
(thesaurus)

'beach popular with an eccentric' is the wordplay.
'with' means one lot of letters go next to another.
'eccentric' indicates an anagram.
'beach'+'popular'+'an'='beachpopularan'
'beachpopularan' anagrammed gives 'UNAPPROACHABLE'.

I've seen this clue in The Independent.
