Right, no need to make this complicated. Clearly you walked here, so clearly you can walk back. And, in fact, there are your footsteps. Probably yours, at least, and not any of the other hundreds of people milling about here. Right, off you go. After fifteen minutes of late-night stumbling, you somehow arrive at the entrance to a cave in the cliffside you've never seen before, which is weird. There's also a windy path that heads along the outskirts of the festival and there seems to be some movement out that way.
