No, Pokemon Sapphire Version does not have a Battle Frontier. However, Pokemon Emerald and Pokemon Platinum do have the Battle Frontier.
There isn't one in sapphire its just in emereld.
Pokemon Ruby and Pokemon Sapphire do not have the Battle Frontier, instead they only have the Battle Tower. It was not until Emerald version that the Battle Frontier was added to the game.
=No, But there is a Battle Tower there. The battle frontier was added only to Emerald Version, and therefore is Completely unaccessible to ruby/Sapphire Version. Sorry.=

Pokemon Sapphire is a GBA game - since a DSi does not have the GBA slot unlike the regular DS or the lite, it cannot play Pokemon Sapphire.
Beat the Elite 4, after which construction on the ferry will be completed and you'll be able to go to the Battle Tower (Ruby and Sapphire)/Battle Frontier (Emerald).
