The extra 6 holes "W, X, X1, X2, Y, Z" begin after hole #15. To play them, the Blue tee for W is near #16's Blue tee, the White tee for W is back and to the left of #15, towards #14's White tee.
X1-X2 are new holes that begin after hole X, take the trail. Play Y after them.
The BLUE (long tee) is to the right of #12's fairway and near hole F's tee, it shoots directly over the water and the rock wall is the O.B. line.
The WHITE (short) tee is a backtrack to the right side of the pond relative to the long tee. It shoots over the corner of the pond.
The WHITE (short) tee is about a 500 ft. walk along the fence! The basket is near straight ahead, beyond the old ball golf green. It has 2 pin positions but they're in a line easy to see which is in.
