you want to get on that log highlighted in yellow. shoot your hook at red X, then swing in direction that red line. you will probably have to rehook onto that yellow log as you wont get much height.
Once on that yellow log shoot directly up (its best to jump then shoot in air) at the log above you (2nd highest log).swing forwards and backwards to get height (not round in circles) then rehook onto that top log when you are VERY close to it and at height of swing. If you are going at a speed you arent confident with when you are supposed to hook onto that top log, return to yellow log and try again at another angle.
