Ruins of St. Paul's and Senado Square — the stone facade of a 1602 church is Macau's icon, and it is free. The walk up from Senado Square's wave-patterned tiles passes bakeries handing out free almond-cookie samples. Come before 10 am to beat the tour groups.
Macau Tower — the observation deck at 223 metres costs around MOP 195 ($25). The reason thrill-seekers fly in is the world's highest commercial bungy at around MOP 4,000 ($500), plus a skywalk around the open outer rim for about MOP 888 ($110). Sunset slots go first.
The Venetian Macao — the world's biggest casino resort, with canals and singing gondoliers indoors. Walking in is free; a gondola ride is about MOP 145 ($18). Worth an hour even if you never gamble.
teamLab SuperNature — a huge digital-art space at The Venetian, similar to Tokyo's teamLab. Tickets around MOP 268 ($34). The best rainy-day option in the city and very photo-friendly.
Resort shows and the Cotai Strip at night — walk the strip past the Parisian's half-scale Eiffel Tower (deck entry about MOP 88 / $11), the Londoner and the MGM light displays. Lobbies and outdoor shows are free. The headline ticketed show is the water-stage spectacular at City of Dreams — book ahead for weekend seats.
A-Ma Temple — the 500-year-old seafront temple that gave Macau its name, free to wander and a calm counterweight to Cotai. Skip the decorative cable car at Wynn Palace if pressed for time — it is a short loop, not a viewpoint.
