On the blue side, have one going over the wall from the side gate into a point between wolves and blue buff wall. One from that end tunnel directly into blue. One across mid-lane (out of sight from your opponent). One from around raptor bush directly into red, one from red out into red river bush (the one facing the river), one from the side bush red wall into golems (the other red buff bush), and from base wall side gate directly into red. It helps a lot to control your tri bush as reksai because it makes it a lot easier and safer to gank from there. You don't want to focus too much on tunneling on your blue side because blue side is the easiest to counter jungle. Having one that goes into wolves and into blue should suffice for the blue side. Also, tunnel from top of blue side jungle into river side bush for quick lane entry. But don't go there and setup tunnel, usually doesn't stay up long and they'll knw you were there. The reason i really like the mid lane tunnel is because if your mid is being dived and you ulti there in time, its an easy save. some other bushes you can tunnel in is top and bot lanes. If the opponent doesn't see you go into the bush, tunnel directly into the edge of the map and it'll cut the tunnel short, effectively hiding it.
