Does the Carcassonne Hunters & Gatherers tile with 3 fish, 2 rivers and 2 forests have a menhir?
Simple answer: If the tile doesn't have a picture of a menhir, it doesn't contain a menhir.
I suspect the point of confusion here is differentiating between &quot;tiles with a menhir on them&quot; and &quot;menhir tiles&quot;. The menhir tiles are a special stack of tiles that you play from after you complete a forest with a menhir in it; these ones all have a special back and should not be shuffled in with the regular tiles:

(note: other editions of the rulebook refer to the menhir tiles as &quot;bonus tiles&quot;, which is boring but also less ambiguous.)
Those menhir tiles are the ones listed in the instructions you quoted, to showcase their added value. This does not mean, nor is meant to mean, that the menhir tiles also contain a menhir.
