My son got driving license for motorbike this summer and he was asking that can we go to Tornio and Haparanda to buy some candies. So that we did, but as we didn’t want to ride on big E4 road we planned route that goes as near as possible E4 but is as much as possible gravel roads. We did good job all the way to Simo but after that it was tarmac to Tornio.
Here is link to GPX file (I don’t take any responsibility about route or is it legal or not, so it is fully your own responsibility when / if using this) :
