Sent for a trip along the esplanade (3,5)
I believe the answer is:
sea front
'along the esplanade' is the definition.
(esplanade can mean a walkway by the sea)
'sent for a trip' is the wordplay.
'trip' indicates anagramming the letters.
'sent'+'for'+'a'='sentfora'
'sentfora' is an anagram of 'SEA-FRONT'.
(Other definitions for sea front that I've seen before include "Eg, promenade" , "No faster (anag.)" .)
