You know you will need to pass them and then head west past another Yrthak nest and then further away through less open tunnels.

Stealth Roll by everyone with advantage beats DC 14
You sneak up to the goblins and either quickly kill them or surprise them and they take off running. With them dealt with you are able to continue west through the cave and avoid an encounter with the far deadlier Yrthak.
Someone Fails the stealth roll.
One of the goblins spots you and they all find defensive positions behind remnants of wagons and rocks. One of them sends a light up into the air and you can see goblins coming from the tower. Then one of them comes out and attempts to use Drow sign. "Pig hand speak. You give we go."
At best you think maybe he’s trying to shake you down for some gold. In all honesty though he is just the absolute worst and you practically want to gouge your eyes out before watching him butcher the elegant hand motions of Drow sign even more.
"I’ve Eilistraee’s guidance, for any who need it." He signaled to the others.
He lowered his piwafi, but took the lead to provide a path that avoided detection for the others.
