In the Azure Span in Dragonflight, there is a tuskarr boat in Iskaara that offers an around the Azeroth trip! We’ve sat on the boat and taken the entire trip.
The trip starts by the dock in Iskaara, Azure Span, and stays docked for the usual 3 minutes while there. The Tuskarr boat moves slower than your usual boat, and the entire trip takes around 50 minutes.
