Hey Guys,
This is the first guide I've written, so here goes. I've considered Olaf my main for a while now, and have tried several effective builds and have narrowed down the build that works almost all the time, regardless of enemies. Olaf is one of the best jungles imo even better than WW in some cases if you get this jungle guide down to a perfection. Olaf in this build is an AD/HP carry who is able to initiate team fights and able to chase down and kill champs.

My rune choice for my jungle olaf is different from other guides but it works alot better when playing him. I use Greater Mark of Desolatio, Greater Glyph of Celerity, Greater Seal of Resilience and Greater Quintessence of Alacrity. these help me really speed through the jungle and makes the jungle pretty easy. this allows your to spam your W to really keep your HP high and avoid being in low hp.

Small Golems, Wraiths, Wolves, Blue Golem, small golems, red lizard, wraiths, wolves, and then start looking to gank. you should be about the same level as your mid if your a fast jungler. When ganking from the forest make sure that you warn whomever is in that lane that you are about to gank.

when ganking you need to look where the enemys are in the lane. if they are pushed up to far then you should pop your ghost, run in pop your w, throw the hammer so that it hits them but ur still able to pick it up while running, then auto attack and hopefully you will get a kill or an assist.

I go fairly standard masteries, no major surprises. I go 21-0-9, taking improved ghost and ghost I take the improved duration of buffs in Utility as well as 4 points in experience. No need to take defensive masteries because of our seal runes.

Well thats pretty much it, ill keep updating if i find a better build than what i have above but im pretty certain this guide is top notch. Hope your enjoy playing olaf as much as i do. PLEASE TELL ME YOUR OPINNIONS AND WHAT I SHOULD DO TO MAKE THIS GUIDE BETTER. thank your all and vote up!!
