Temporary stay during Thurso journey (7)
I believe the answer is:
sojourn
'temporary stay' is the definition.
(I've seen this before)
'during thurso journey' is the wordplay.
'during' says the answer is hidden in the clue.
'SOJOURN' is hidden within 'thurso journey'.
(Other definitions for sojourn that I've seen before include "Stay temporarily" , "Relaxed, tolerant" , "Stop" , "Reside temporarily" , "Temporary residence" .)
