There are plenty of things to do at the battle frontier. I won't go into it for the sake of time. There are 7 facilities in the frontier. In each of the places, your abilities and pokemon are tested on other trainers. If you beat 7 trainers in a row, you earn different amounts of Battle Points (a.k.a. BP) . Its that simple. Once you earn enough BP, you can get really good items such as TMs taught to your pokemon, Rare Candies, Calcium, Iron, HP Up, Carbos, Protein, a variety of pokemon dolls, and other interesting items.
