Pathfinder Achievement in Unravel
Make it to the water wheel without using a log raft
How to unlock Pathfinder
This will be found in Chapter 5, "Off the Rails". After you have crossed the first bridge in the chapter you’ll come up to the area where this achievement will be unlocked. After reaching the yarn checkpoint you’ll see an area above you with a door flap and the log that can be used in this section. Underneath that will be a lasso point that you’ll want to jump to then swing over to the right where the wall comes out of the water. Climb up on top of it and lasso up to the point above you and to the left. Stand on the mini wooden ledge and jump over to the circular wheel to the right to drop down and hang there. Then swing on over to the wooden platform on the right. Hop on the wooden post, lasso up onto the wooden dock, jump over the opening then you’ll reach another point where you’ll need to swing. Drop down while holding to give yourself enough slack to swing over to the metal chain. Then just swing from the metal chain over to the rock and jump up to reach the yarn checkpoint and unlock the achievement!
