Macau is fascinating, nothing like Hong Kong or China really as it was once a Portuguese Colony. You'll notice that the pavements have beautiful Portuguese tiling as well as many of the houses there. Macau is also now the top gambling market surpassing Las Vegas in 2004. This gives it such a contrast from the traditional houses to the modern casinos and resorts. While we were in Macau, we stayed at the Studio City resort and watched the Batman 4D show which was so surreal. We also got to try a lot of Macau delicacies such as Portuguese tarts, jerky and almond biscuits and ate them by the river with China as my view.
One of the main reasons to visit Macau (apart from gambling) is catch a glimpse at the Ruins of St. Paul which was built in 1602 - 1640. All that is left is the front wall of the church which was under maintenance whilst I was there. There's also a beautiful lotus garden (where I was attacked by mosquitos), Senado Square and some temples to see. If you're tired, there's always a nice resort just around the corner to relax in with air conditioning.
It's strange seeing churches and things associated with Christianity around the place considering the people of Macau are mostly Buddhist or follow Chinese folk religions now. It all acts as reminder of the historic past and it's ruler, the Catholic church.
The downside to Macau is the roads. Seriously, it's such a pain! You know when you're in a shopping centre and you see a shop and don't know how to get to it because there's an awkward glass wall or something in between? That's exactly how the whole of Macau exists. Therefore, you see your destination which in reality should take 10 minutes to walk to but... there is no physical path for you to walk on so you have to catch a bus which goes around in circles and you get there at last an hour later. Getting around is horrendous unless you drive a motorbike like most of the locals and can sneak in between all the traffic. Some days, it took an hour to get from Taipa island to Coloane island.
Overall, I think Macau is an interesting place. It's possible to get it all done in a day actually because of how small it is. It has a unique culture with an interesting history. If you're in Hong Kong and not sure what to do, a trip to Macau is a good idea. Just remember to bring your passport unlike me hahaha!
