Downtown Summerlin is a 400-acre outdoor shopping, dining, and entertainment district in Summerlin South, developed by The Howard Hughes Corporation and opened in October 2014. It sits adjacent to Red Rock Resort and includes a large amount of retail space, commonly cited at roughly 1.6 million square feet, along with a mix of restaurants, entertainment venues, and Class A office space. Before it took its current form, the site had gone through a couple of earlier names and a slower path to completion, a common pattern for large mixed-use developments that get planned years before they're actually built.
Unlike a typical enclosed mall, Downtown Summerlin is built as a walkable, open-air district, with wide pathways and shaded outdoor seating rather than a single indoor structure. The layout is meant to function less like a conventional shopping center and more like a town square, something Summerlin's own materials describe as the community's gathering place rather than just a retail destination. Mountain views are visible from several points throughout the district. My Living in Summerlin overview covers how this district fits into the broader community if you're comparing Summerlin against other parts of the valley first.
Before settling into its current form, the site went through a few name changes tied to different ownership groups over roughly two decades. It was originally known as Summerlin Centre, then The Shops at Summerlin Centre, before The Howard Hughes Corporation took over development and opened it under its current name in October 2014. Ownership passed through several companies during that stretch, including the Rouse Company and General Growth Properties, which is fairly typical for a large mixed-use development that takes decades to reach its final form.
Downtown Summerlin is also served by an RTC Transit facility located within the district itself, giving residents without a car a direct public transit option to reach the area, in addition to the surface and garage parking already available for drivers. Current routes and schedules are available through RTC Transit's own site.
