I was on a hike and read a plaque that said this area used to be completely covered by water. My question is, where did all that water go? Just absorbed into the ground? Evaporated?

It would have been absorbed into the ground and/or tied up in glaciers and polar ice caps.
It’s not the water that changed but the geology.
Duo to the movement of continental plates, some parts of the planet were once ocean floor but have been pushed above water.
Depends on what area you were at precisely, but the water most likely didn’t go anywhere, it’s the ground that moved. Some areas the ground is lifting up, the others it’s sinking, Earth isn’t so rock solid over geological timeframes.
Once upon a time there was an ocean (or maybe a sea, or a lake?). Over time, sediment (sand and silt) settled on the bottom of that ocean. Eventually that sediment was buried so deeply, and was under so much pressure and heat that it became rock.
While this was happening, the continents slowly drifted, and in some places, this caused the rock to be pushed upwards, until it was no longer under water.
So the water didn’t go anywhere. the sea-bed was lifted up until it was above water.
Lots of different things OP.
Water could’ve gone underground, it also could’ve been absorbed in some extent by the biosphere (trees, plants, etc). Water inside of you means water that isn’t on the ground after all. You could also have water that’s in the air, climate change is infamous for increasing global temperatures and hotter air holds more water in it.
Also glaciers! Yeah a whole lot of places it could be
