Guinsa Buddhist Temple in South Korea. A temple complex, with tons of temples nestled into the mountains, going up, up, up. Each section seems like the whole, because you can't see anything else but the buildings towering above you almost as much as the mountains are. But then you glimpse this little hidden staircase and keep climbing and discover yet another level of the complex, brightly painted temples and footbridges all around. You look back, and discover that hidden staircase was one of many, a myriad of winding routes all leading to the same place... eventually.
