This is the tile pattern from the square around the Opera House, the theme is the meeting of the waters. If you have been to Lisbon, Portugal, they have the same pattern on their promenade avenue. I believe they also have this same pattern on the beach walk in Rio.

The tour also included a stop at the local zoo.

Boa Constrictors

This is the area around the port.

This area above is around the port. The port is also walking distance to the Opera house, just in a different direction. I saw some great photo opportunities on the way back into town from the zoo and in hind sight, it would have been nice to skip the zoo part of the tour and spend more time around the Opera House.
