You can't go to Hoenn in Pokemon HG/SS.
You cannot actually go to Hoenn in SoulSilver, but you can catch Pokemon from Hoenn on Wednesdays with Hoenn Music on the radio.
No, it is not possible to access the Hoenn region in either SoulSilver or HeartGold. However, you can catch Pokemon from Hoenn. On Wednesday, the Pokemon march station is a Hoenn sound. To get the Hoenn Pokemon all you have to do is set your Pokegear radio onto the Pokemon march station on Wednesday after you have defeated Red.
You are already there. Hoenn is the entire region in Pokemon Ruby/Sapphire/Emerald.
You can get some by using Hoenn Sounds on your radio and some Hoenn Pokemon are just in the grass and in the pokewalker. Go to Serebii.net for info on where to get certain pokemon.
