It is very important to counterjungling early, or else you are putting yourself at a disadvantage by not abusing your early clear and 1v1 potential.

Ganking is an important part of jungling, your best way to gank is to activate your e, and try to get your fear off behind your enemy, to make him walk to your turret, you can do this by:

1. Being behind him in the first place

2. Holding down your Q to go through your enemy

After level 6 and maybe a tanky item, you can tower dive, also, your ult is a fantastic ganking tool, abuse it.

The unique thing about Warwick is your ability to solo jungle camps, that means if it is not warded, you can just hop over to someone's red or blue, and start there, try to get to a bush early with your speed boost at the start of the game and make sure no one wards the bush. Ward the buff after you kill it and go to your jungle to continue your clear.

Onto your actual pathing, determine which lanes are the most gankable. If your teammate at top has cc, will not push the wave up and is not losing, then they are very easy to gank. Start on their side for an early gank, and start on the opposite to get a level 3 gank off.

Your first clear should always avoid raptors as they will put you on low health.
