Ashen Volcano is probably the best place to chest farm because ganking usually takes place near towns like Castillian shore and East Peninsula, and Bronze Grasslands can make players hide themselves in the grass. So here you go, my Ashen Volcano chest route: 
Make sure you follow the colours:

Notes
------------------------------
- When doing this at night, make sure you have a torch, as it is hard to see in Ashen at night.
- When going to the
(middle platform in the volcano), try to get as high as you can and use your high jumps. Make sure you land on the 2 rocks, a fall from high up will kill you when you land because your character glitches through the ground and touches the lava underneath, making you die. - When leaving the middle platform, wait for your high jump cooldown to end. Then, jump towards the wall of the volcano towards the
marker. there should be a piece of land underneath. - When you reach , you can go back to and collect chests or raid ships on the way back .
I will add the cave to this when you can destroy blocks again.
