Home to beaches and national parks, Sydney is a city outdoor lovers can embrace. Expanding that appeal, two new developments have turned industrial plots into beauty spots. Opened in September, the new Barangaroo Reserve reclaimed 14 acres once piled with shipping containers on the harbor. Inspired by the precolonial landscape, the newly contoured headland edged in sandstone features a shoreside promenade and, temporarily, the Copenhagen restaurant Noma, which will take up residency this month for 10 weeks. The Goods Line, a new elevated walkway, opened in August, repurposing a defunct train line. More reclamation: the new Old Clare Hotel joining a 19th-century pub and brewery offices. More convenience: American Airlines introduced daily Sydney to Los Angeles flights in December.
