The good folks at Roberts Retreat Lodge say that Google's directions to the cabin are wrong. So following these instead: 

HERE ARE THE DRIVING DIRECTIONS:

Unfortunately, Google Maps and Mapquest do not take you to the correct location with the address. From wherever you are located, you can google "Vamoosa, OK" and the property is only 4 miles East from there, so this will give you an approximate driving time. So first look up directions to Vamoosa, OK and then follow these instructions ...

•Off Hwy 377/99, turn EAST onto EW1400 Rd - there is a black sign with white letters “Vamoosa Baptist Church” where you turn (this road is directly on the N side of the Vamoosa Cemetery)

•Continue straight past the church on your Right, through the 4-way stop, stay to the Right when the road V’s (by the mailboxes on the right), and continue past the “Dead End” sign

•Turn Right into the Roberts Retreat gate entrance

•Go for ¼ of a mile and make your FIRST LEFT

•Continue on this road and take your FIRST RIGHT (do NOT go through the RED gates)
​
•Go through the black gate and continue to the Lodge
