All optional tombs completed.

In total, there are seven Tombs scattered around the island. Their locations may not always be noticeable or even obvious, so tracking them down can be tough. They can usually be found by noticing white chalk markings scratched on the rocks and cliffs of the island this means that a Tomb is nearby. Alternatively, purchasing the Cartography skill in the Survivor Skill tree will also reveal the locations of all the Tombs on the island. Take note that you will need to purchase the Specialist skill before purchasing Cartography

Overall, each Tomb will essentially be laid out as a puzzle, where the reward is a grand Treasure Map that shows all collectibles for a specific area of the island. It is up to you to figure out how to proceed through the Tomb by using your Instinct ability and solving these puzzles.
