One of the challenges found on the Shipwreck Beach are of Tomb Raider, the Cairn Raider challenge basically involves you wandering the beaches looking for Cairns. They’re simply little piles of stones arranged as landmarks. Here’s where to find them:
Cairn #1: Coordinates – 712470, 3416008
Location. Head to the waterfall at these coordinates. Directly opposite the falling water is a tall pillar of rock with a climbable surface on it. You can’t reach it though, as the surface is just a little too high for Lara to reach. There should be some buoys wrapped in rope nearby though, and you can use your rope arrows to yank them under the wall and use them to get some extra height.
Cairn #2: Coordinates – 712484, 3415992
Location. These coordinates lead you to a large rocky hill north of the northern tomb entrance. Take the path that circles around and up the hill, and you’ll find this Cairn on a ledge above.
Cairn #3: Coordinates – 712471, 3415995
Location. From where you first come onto the beach, there’s a platform that will be in front of you with a cairn on top of it. You can also see a large battleship in front of you off the shore from here.
Cairn #4: Coordinates – 712503, 3415950
Location. To the east of the southern tomb entrance on the map, there is a path along the edge of the ocean that has a wooden fence. The cairn is found along that path right next to the fence.
Cairn #5: Coordinates – 712522, 3415950
Location. To the south, on the other side of the water that blocks the beach, there is a climbable structure you must ascend. Once you’re up top, use a pole to swing over to the rocky platform. The cairn will be on the ground at the end of the platform next to a large tree.
