The Arena is occupied Friday through Sunday. Nanjing East Road will not be a place to drive. If you have tickets, go. If you do not, this is not a weekend for Xinyi.
Silvergrass on Yangmingshan has started. Qingtiangang is the postcard; it is also a bus, a layer, and an hour of wind that is not the basin. Go in the morning. The mountain makes its own weather, and it does not consult the Arena schedule. Eat noodles in the village. Be down before you are tired of being wet.
The other honest option is Yingge. The New Taipei Green Life Festival is on the museum grounds this Saturday and Sunday — outdoor, ceramic, and actually for families rather than for a timeline. Take the TRA. Come back with one object you will use, not three you will photograph.
The city is loud this weekend. You do not have to be in the loud part.
