Anyway, less stuffposting, actual questionanswer...
There's no "Always start from here" sort of trick, you just kinda brute force your way up then.
Alright, time to start swinging again. Seems I get halfway up and slam into one too many branches too fast and splat, or miss a hook and fall... to a splat.
Here's how you beat the log challenge.
go to the volcano and farm dynamite. get at least 20, so if you mess up you can try again.
obtain a shield.
find the area on the log challenge that has a high cliff, sorry i dont have a picture.
drop i think 4 dynamite and then AIM YOUR SHIELD DOWN
the blast will take you to the top but BE READY TO HOOK ON.
hopes this helps~!
