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
While São Paulo’s concrete sprawl doesn’t offer the verdant beauty or mythic beaches of Rio de Janeiro, its thriving art and food scene has in recent years transformed what was once just Brazil’s financial capital into its cultural epicenter. Stroll the city’s gritty alleyways and avenues to see where celebrated street artists Os Gemeos and Eduardo Kobra got their start. São Paulo’s Art Biennial, which is second to Venice’s in longevity, kicks off in September 2018 and showcases contemporary talent, both international and homegrown. For a truly immersive experience into Brazilian fare, don’t miss Alex Atala’s D.O.M., named one of the best restaurants in the world. Atala champions native ingredients — from priprioca root to ants, often foraged from the Amazon region by the chef himself — and weaves them into his inventive dishes. The arrival of luxe hotel brands is another signal of the city’s burgeoning cosmopolitan status. The prestigious Oetker Collection, with only nine other properties (in glitzy places like Seychelles and the Côte d’Azur), recently opened Palácio Tangará, a gorgeously appointed mansion set in leafy Burle Marx Park, a welcome oasis from the city’s high-rises. The Four Seasons will also debut a new property in mid 2018, marking the brand’s first foray in the country. —Karen I. Chen
Last summer, the museum expanded its artistic footprint by over 130,000 square feet, making it the largest contemporary art space in the country. The new Building 6 houses long-term installations by artists like James Turrell, Louise Bourgeois, and Jenny Holzer. Two new museums are still in the works for North Adams, both spearheaded by former Guggenheim director Thomas Krens. At the Global Contemporary Art Museum, curators will work directly with artists to acquire and commission site-specific pieces, while the Extreme Model Railroad & Contemporary Architecture Museum will showcase works by the likes of Frank Gehry and Zaha Hadid, all built in miniature as part of an elaborate model train system. Design is also top-of-mind at Tourists, a modern take on the roadside motel that’s set to open this summer. The resort — situated on 55 acres at the convergence of the Appalachian and Mohawk Trails — will have 48 rooms, each with floor-to-ceiling windows that put the focus on surrounding vistas. —Fiorella Valdesolo
