A man-made lagoon with boating and water sports on the Strip—that might sound familiar. It was part of the original plan for the Bellagio, which was called Beau Rivage in its early iteration. The curved blue glass resort would have sat on an island in the middle of the lake, with 360-degree views of the “aquascape” from inside. Instead, we got a smaller lake. Now, Wynn is bringing the idea back, with a twist: The lagoon will anchor a mile-long boardwalk and have a twin-peaked mountain at its center. Shops, ziplines, electric ferries, nightly fireworks—this redevelopment of the Wynn golf course will not lack for things to see.
