80s, 90s Horror - Woman climbs ladder to escape monster

There is a scene where a woman is walking through an old western-style town and falls into an underground tunnel, and there are cutscenes where a monster of some sort is coming for her. The monster is in first person going through the tunnel during these scenes. The woman, I believe, realizes she can't make it back up from where she fell, and goes through the tunnel until she finds a ladder and escapes before the beast gets her.

Maybe "Creep"

https://en.wikipedia.org/wiki/Creep_%282004_film%29

Party-loving Kate wakes up in a London tube station to find the place locked up and deserted. With no choice but to stay there until morning, Kate soon finds that some things are much more frightening than being alone, as she heads into the labyrinth of tunnels beneath the city, pursued by an unknown attacker.

or "The Canal"?

https://en.wikipedia.org/wiki/The_Canal_%282014_film%29

David and his family move into a period house by a canal, and dismiss rumors of the place being haunted. David starts having nightmarish visions when he suspects his wife is cheating, and he begins to descend into madness.
Those are really good suggestions, but it is a much older movie
