I could never find a way to bring my sub down into the really deep places, which meant that I used the mech suit and built a serious survival base down there, and until I had that base really built up, I was ferrying things back and forth through that entire area from my sub. I probably made 15-20 total two-way trips.
IIRC the mats for the biggest depth module were in the inactive lava zone. I built a little base by the tree as a staging ground before heading deeper, but got the mats I needed on the first voyage and only stopped back in a few more times when passing by, mostly because I also set up a little farm there and also because it was just so beautiful there, hanging over a dark void surrounded by all the glowing plants and fish.
yeah it wasnt the depth i had issues with, it was literally fitting my submarine down there. my entrance to that entire subterranean area was too narrow for the sub. but yeah, i also made my base near the tree, i never really felt the need to build any deeper than that. excursions staged from there seemed to do just fine.

There is an entrance large enough for the sub in the north between the bulb zone and mountains.

IIRC there are three entrances to the river and two are large enough to get the sub through, though one of those is a tight fit.
