Guia Park is the largest park on the Macau peninsula, and a popular green space for locals and visitors alike. There are gardens, a small church, the world’s shortest cable car, tunnels (former air raid shelters), and at the summit, a fortress, lighthouse, and great views!
We highly recommend running in Guia, although it’s hard to escape the hills. The best bet for running is on one of the smaller roads or trails (not seen on Google Maps) that basically parallel the main loop road. It’s just shy of 2 km and has 215 feet of elevation (not overly steep). A good place to start the run is Jardim da Flora, take the steps to one of the trails, and do the loop. There are billboard maps that have trail details.
