During our vacation 6/12 - 6/19, we rented a Yamaha Rhino & took off to find the Natural Pool. It wasn't easy, but we found it using directions I found on the net. While I was there, I recorded the GPS coordinates for future use. If you are planning to go it alone, these might come in handy:
12 degrees, 31.42 N
069 degrees, 55.84 W

Have Fun!!!!!!!!!
