Veiled Grotto

It's called "Veiled" for a reason. Well worth the effort though. It gives you a great vantage point for future WQs in the area.

There is an alternative to avoid most of the Mogu area. Here is that path with the additional waypoints.

Path from Xibala up into the jungle starts at 42.75, 68.90
Path splits, stay straight at Warport Rastari - 44.70, 63.63
Path splits, turn left at Village in the Vines (bridge to Dazar'alor on right) - 52.78, 49.32
Path splits, stay straight on Old Merchant Road to avoid Mogu area - 52.25, 43.98
Path splits, turn left on Old Merchant Road - 52.69, 40.45
North Entrance to Temple of the Prophet - 49.65, 38.01
Stairs up to jungle path in Temple of the Prophet (turn right after entering temple) - 49.37, 38.70
Faded path to Veiled Grotto - 44.79, 37.72

Happy Hunting!

The key bit here, whether you're coming from the south, east, or north, is to enter the Temple of the Prophet area's north entrance at roughly 50, 38. Headed south through two arches, take the first set of stairs on your right. From there sticking to the path is obvious.

If you also have Grimwatt's Crash, you can glider to there from here.
