Travel to view spectacle first (8)
I believe the answer is:
sightsee
'travel to' is the definition.
(sightseeing is a kind of travelling to)
'view spectacle first' is the wordplay.
'view' becomes 'see' (synonyms).
'spectacle' becomes 'sight' (spectacle can mean a sight or display).
'first' says to put letters next to each other.
'see' put after 'sight' is 'SIGHTSEE'.
(Other definitions for sightsee that I've seen before include "Play the tourist" , "Visit places of interest" , "do this in a tourist spot" , "take in views" , "What a tourist does with vision" .)
