Gerudo Desert - Piece of Heart Location

There is only one piece of heart for you to get in Gerudo Desert and it's located in the Bulbin Fortress just before the entrance to Arbiter's Grounds.

There's a large beast roasting on the fire just before the stairs leading up to Arbiter's Grounds that you can smack with your sword a few times and destroy for a piece of heart. That's really all there is to this one, it's super easy to get.
