God Of War Ragnarok Washed Ashore Treasure Map Solution
First you will need to get the treasure map.
This can be obtained by going to Alberich Island. Once here use a spear to climb the wall on the right (👀 the spear is unlocked during chapter 10). Then destroy the green rocks on the left with sonic (green) arrows on your left.
On the other side of the rocks go right and then look right to see a rock that you can destroy with the spear. Return to where the rocks were and grapple across to the big wooden platform. You will be able to find the treasure map next to the device on the right.
To find the treasure you will have to go to Dragon Beach. Here go to the right end of the beach to find the treasure.
