The only way for an outsider to enter Wano is to go over the Waterfalls. For most pirates it was a seemingly impossible task. Even the Beast Pirates were surprised that the Big Mom pirates were able to do it. Now even though Rocks never actually went to Wano, there is little doubt that he didn't know about Wano's importance. Considering he know about the Ancient Giant Shipwrights and the truth about Imu and Davy D Jones.
But what if Rock specifically sought out Shiki for his Devil Fruit to be able to float over the Waterfalls and get to Wano eventually. but just never had the chance to actually get there.
