Saw the sights (6)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">saw the sights</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for toured that I've seen before include "Went on holiday journey" , "Went on sight-seeing expedition as to foreign parts" , "Went on sight-seeing journey" .)
