It's a short, narrow smooth hole, there's no good or easy way to climb out. Any rescue effort will be an hour long process for sure. As you fall down you rip apart layer and layers of cobweb.

The spiders aren't venomous. They aren't huge - in fact they are tiny, most of them not even larger than a centimeter or two. But there's hundreds of thousands of them. You close your eyes, you hold your breath as you feel them covering every single inch of your body. You are in utter darkness and the only sound you will be hearing until your party catches up in half an hour is the occasional noise of them crawling into your ears.
