I went there around level 4, blew myself up several times trying to find a way through, and finally gave up - concluding that I clearly wasn't equipped to handle what lay beyond the explosives. I was right. I came back later, bypassed the traps, and cleared that area.
Keep in mind that you can walk all the way to the final boss's dungeon without leveling up. Nothing is stopping you, except for traps, and enemies which will kill you in a single turn if they catch you. The game doesn't prevent you from exploring into areas that are too high level for you. You just have to know how to turn back when you hit an obstacle you can't overcome.
