Holes in the ground can be found on Plateau (cave entrance), Lynx (on top of rock), Canyon (various places), Paradise (sulphur cave entrance), and Spire (cave entrance, not mithril cave). I'd reccomend paradise, as it's got plenty of noobs to trap, and the hole leads into a dark cave. The only flaw is that you can jump out from the platform you enter onto.

While you can't dig a hole, you can raise the height of the ground (such as with a lot of thick structure walls), then have a hole in that. If you were to do this, I'd make a convincing(ish) extension to a mainland plateau out of medieval support walls, and roof the top off with compost or leaves. Then you could make a gap in the roof, and you'd have a deep hole you could trap someone in. This would likely be the best way to make a hole for noob trapping, albeit the most difficult.

Probably the best way to make a noob trap however is to just trick one into entering a cave, then abandoning them. Much less hassle.
