In the grass but Suicune moves a lot so you will not always find it there.
You first find suicune at cianwood city. Then at Vermilion city. then at rout 14. you fight suicune at route 25
If I remember right, suicune is on the right hand side floating on the water. Ofcoarse you can't actually get to him but once you see him, there will be a short clip of suicune running away from you again
Suicune can be found anywhere where grass is the best route is route 1.
Anywhere around kanto usually its found on route 1.
(NOTE: The Following Information is for Pokemon HeartGold) The first time U come across Suicune wil be at Ecruteak City at the Burned Tower, then at Cianwood City, and you'll even run into Suicune on rout 42. Afterwards I don't know I haven't gone that far just yet.im improvin.after u see suicune at route 42 by mt.mortar go to route 14 and 15 and he should be on the water.after that u go where misty is on her date by bills house and that's where u faint of catch him.And hes not a runner:)
suicune apears at the port in vermillon city and later at route 14 and at last go to route 25 and catch suicune
suicune is on the right side somewhere on route 14. after encountering suicune there, if you met misty at the end of route 25, you'll find suicune there and you can battle it.
After route 14 he will go to his final location: Route 25. But! If you kill him in route 25, he will re-appear after you beat Red.
To get Suicune first you will see it north of Cianwood City, then you will see it outside the entrance to Mt.Mortar in Route 42. After that you will see it in Vermillion City, then route 14. Only after Misty has returned to her gym you will fight Suicune on Route 25 outside of Bill's House.

you go to the ocean/sea (next or in between rout 14 & 15)then you'll see suicune. it'll then run up the water. then a man will come and challenge you to find suicune the fastest.
In Pokemon HeartGold and SoulSilver you can catch Suicune in Route 25 however if you have knocked it out during battle then you can defeat Lance and then Suicune can be found for future battles in the Burned Tower however Suicune cannot be found in Route 25 until you have released it from the Burned Tower and then you have encountered it in Cianwood City, in Route 42 which is the outside entrance of Mt.
