You should now be able to cross the bridge and enter the Black Canyon Mines. To the north-west, there is a Lost Caravan. You might also end up fighting elite bosses here, particularly Beyatt The Elusive One. It is not guaranteed that Beyatt will appear, but this area is the only zone that he can possibly spawn in throughout the entire game.
There are also several side dungeons and event quests to be found in this area, including Sirocco Caverns, Tunnels of the Rockworm, Deserted Cellars, Blood Cellar, The Ruins, Chamber of the Lost Idol (The Idol of Rygnar), The Crumbling Vault and the Restless Sands.
