If you are ferfering to the cave painting in the cavern in Celestic town, then let me the first to tell you that it doesn't open. The best entrance is by the cycling road, but you won't be able to go all the way until the leader of team galactic goes there. If you are refering to the gate blocked by rocks in the cavern, then again I say that it will only open when the boss heads up to spear pillar (after you release the lake Pokemon from galactic hq).
