Please Pay Attention to Where You're Going

As you might imagine, there are a few signs of erosion along the coast, where the relentless ocean has scoured away for millennia at the coral cliffs. If you weren't paying attention to where you were going, you might fall through a hole like this and end up forty or so feet on the beach below.

If you did that, you'd find yourself on a beach of Bottom Bay–like beauty, but I'm not sure how you would get off it.
