Standing before the plaque, head to the right and follow that path down. At the end, stay left, following the path through the bend to the right, and all the way down. This will bring you to a larger road. Once there, turn left and continue on that path. Where this path splits into two, take the right fork, which heads down some more. Continue on that path until you see, on your right, a small set of steps going down, located under three coconut trees. Stop there, facing the stairs, to learn about the Mexican garden.
