South of the map, there should a road that ends going south and splits left and right. (There should be bucket list 19 there) Near that, (the more west side of a few houses) the stone wall ends and that big hill that's present in the rainforest starts. There, there should be a small opening where if you are going at the right speed you can get over the walls and soon if you travel further you just fall out of the map.
If anyone didn't already know, get into a convoy and head to the airport runway. Wait for a message to pop-up above and say *"CONVOY RACE TO KIEWA VALLY?"*, hit X to accept and follow carefully: *cut across the grass and hills to the FINISH LINE point*, and you will see a boat hidden in the ground. That is, if you followed these instructions. Head to my XBOX account; *StormyTundra21* to see the boat taken in a screenshot with a Nissan 240SX.
imagine they put a barn find on the third hidden place. It would be awesome. edit: peeps thought I said the rock, but I meant the little island in which they put a number 3 on it. Smh
