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. Mortar, in Vermilion City and then in Route 14.
In kanto, it appears first at the pier in vermilion, then on the windmill route east of fuschia and finally it can be battled on cerulean cape(route 25).
you have to follow Suicune first. To get Suicune on the run, go to Cinnawood Island. THIS IS IMPORTANT! When you get there someone will battle you. Next, go to Mount. Mortar to the right of Eruteat City(SURF IS NEEDED ALONG WITH CUT). Surf to the right until you get to land. Then, go to Vermilion City on the pier. After that, go left of Fusha City at route 14. Finally, you will find Suicune at Cape Cod after Misty leaves. Good Luck!
You find Suicune sitting on the Cerulean Cape (where Misty was at before she went back to her Gym) after you have found it in Cianwood City, near the Mt. Mortar entrance, Vermilion City and Route 14, it must be chased off each time until you get to the Cerulean Cape. Suicune will only be on Cerulean Cape after you have defeated Misty in a Gym Battle.
Yes you can get Suicune. To get him, you need to go see him in these areas: Burned Tower, Cianwood City, Route 42, Vermilion City, Route 14, and Route 25 is where you will see him.
