One of the most hidden places that really confused me was Training Facility B-T in Gongaga for the Phenomenon Intel 4: Training Facility B-T quest in Final Fantasy VII Rebirth. Like me, you may have thought it was through the airport to the north of it, but actually, it is the other way around. Gongaga’s jungle-like environment can be confusing to navigate. I wasted a few minutes searching around the airport before realizing the facility is actually on the other side, through the ruins in the jungle.
If you are looking for Phenomenon Intel 1: Trining Facility V-B then follow this link.
To find it, head to the Feind Intel 4: Maddened fast-travel point at the ruins in the western parts of Gongaga. Look for an entrance to the north, right before the monsters in the area (coming from the Feind Intel it will be to your left). If you didn’t open the chocobo stand in there, you will be greeted by the little guy leading you to it, if you opened it already you can use this point to reach to that facility. Continue heading north from there, and you will see a mushroom that will launch you to where the Training Facility B-T is. Happy hunting, and don’t forget the treasure that opens after you finish the quest.
