I've wandered the redwoods which I guess are old growth on account of many of them predate Julius Caesar. But sadly from New England everything was clear cut by about 1840. Couple small patches of old growth out in the Berkshires apparently

There’s a few old growth spots left on the edges of the Everglades that ive been in. It is a primeval feeling to stand next to thousand year old cypress trees. In North Carolina I think theres a 2000+ year old cypress stand too

I've been to some in deep northern California. It was awesome to see them in person. Pictures didn't capture the density of vegetation correctly.

yeah
lilley cornett woods in eastern ky is nice, but you gotta call them and reserve a day to hike in advance and its a guided hike
i still havent asked what happens if you have to poop I assume they make you bring a poop bag and pack it out
:( but they do have bathrooms at the visitors center for before and after the hike
