This guide will let you know how to get to the Mushroom Forest in Subnautica. You have to follow the simple instructions in the guide to get there.
Starting from the coral tube sticking up out of the water, you have to make your way northwest or 1 bump to the left or right of the northwest, and you will reach the northwestern mushroom forest.
It is recommended to have a sea moth with an Mk1 depth module, a high capacity 02 tank, a sea glide, and a seacon to mark the mushroom forest to make coming back to it easier.
The only threat you might encounter in this mushroom forest is the bone shark which you can either avoid or kill using the survival knife. And there aren’t many bone sharks in this mushroom forest, so there shouldn’t be any threats.
The coordinates for the location are (-919, -177, 508).
