To better accommodate the millions who visit Iguazú Falls, a UNESCO site of 275 mighty waterfalls straddling the border of Argentina and Brazil, nearby Cataratas del Iguazú Airport is being modernized and enlarged. Within Iguazú National Park, the Ecological Jungle Train, which takes visitors on a 25-minute journey to the epic Devil’s Throat cascade, is converting from gas to environmentally friendly electric trains. Starting this February, travelers will be able to bed down at the long-awaited Awasi Iguazú resort where 14 rainforest villas will each have plunge pools and guests will have access to a personal excursion guide and 4WD vehicles. Expect visits to native Guarani tribes, river kayaking, and jungle treks led by a resident biologist. Selvaje, an upscale 12-room lodge, will also open early this year and will offer a menu of couple-friendly activities, from picnics to spa treatments. For the ultimate in romance, though, Argentinean travel outfitter Mai 10 (run by Travel + Leisure A-List Agent Maita Barrenechea) can arrange private dinners alongside the falls under the light of a full moon. —Nora Jean Walsh

Though decades of civil war made parts of the island unsafe, tourism is on the rise in Sri Lanka, where international visitors exceeded 2 million for the first time in 2016. The momentum is particularly strong along the south coast, which has the highest concentration of hotels and resorts after Colombo. The 172-room Amari resort recently opened on the beachfront in Galle (known for its UNESCO-protected Dutch fortress) with ocean views from every balcony. Water also plays a central role at Alila Koggala, a new luxury eco-resort with 36 suites and private villas, opening 20 minutes outside of Galle in June. The property sits on the serene shores of Lake Koggala and will feature an ayurvedic spa where treatments can be taken on a platform floating on the lake. Further along the south coast, Mirissa Beach is attracting travelers in need of a full mind-body reset. The laid-back surfer town — think Venice Beach minus the tech crowd — comes alive at night with bars and barbecue restaurants overlooking the turquoise bay; when you’re ready to turn in, there are earthy, low-key lodges peppered throughout the jungle, such as Surf & Yoga, which offers daily on-site yoga and private surf lessons. —Alex Schechter
