Easy way to skip that part: Right at the starting area (down the slope with the grunt.) sneak past the enemies, go behind the buildings across the street and in a corner you should find a pile of trash. Drop a grenade at your feet and jump at the right time. You should get up on the ledge above the pile. From here, you can climb up to the top of the building. Once there, facing the courtyard and building, go right and across the buildings. Take another right and go over the gate. Go across the bridge here and jump down. You should see a sign that says Zanzibar. This method is effective because it allows you to conserve plenty of time.
