Find the 3rd backpack in Solarpunk on the far-left island, tucked in a recessed tree spot, and unlock six full rows of inventory with one careful drive.
The third backpack in Solarpunk is one of those pickups that’s easy once you know exactly where to point your vehicle — and frustrating until you do. It lives on its own island out on the far-left edge of the map, far from the central spawn area, on a recessed spot that’s normally hidden under a tree. The run below is short, but the handling matters: ease off the throttle, park with care, and remember how to back out again.
The 3rd backpack sits on the far-left island, well out past the center of the map — drive out to it, carefully park on the low spot where a tree normally stands, and grab the backpack to unlock the full six rows of inventory.

Frequently Asked Questions
How many inventory rows does the 3rd backpack give you?
It completes the full six rows — the 1-2-3-4-5-6 layout. Picking it up takes your inventory to its maximum size, which is exactly why it’s worth the trip out to the far-left island.
Do you need a vehicle to reach the far-left island?
Yes — the island sits well out from the center of the map, so you make the trip in a vehicle, park it on the low spot, and reverse back out afterward. The pickup is built around driving out and parking carefully rather than walking there.
Does the 3rd backpack cost anything to claim?
There’s no cost for it. On the spot itself it’s simply picked up once you park on the low area and jump out.
Where are the earlier backpacks, like the 2nd one?
Backpacks unlock by location rather than all at once, and there’s a separate 2nd backpack spot to find as well.
