Beau Rivage is the reason the Biloxi skyline looks the way it does. When Steve Wynn's Mirage Resorts opened it in March 1999 it was far larger and far more expensive than anything the Mississippi coast had built, and it reset what a casino here was expected to be: not a barge with slot machines tied to a pier, but a twenty-nine-storey hotel with a theatre, a spa, a conservatory and a beach across the road. Twenty-seven years later it is still usually cited as the tallest building in the state.
The date that matters more is 29 August 2006. Katrina had closed the resort exactly one year earlier, drowning the ground floor and everything in it, and the reopening on the anniversary was a deliberate piece of theatre by a city that needed one. Almost everything a visitor touches at ground level here is younger than that day.
What you get if you never place a bet is the point of this entry. The central atrium is planted and replanted through the year, and it is the closest thing on this coast to a public winter garden — genuinely worth walking through in December. There is a large outdoor pool deck, a spa, a theatre that takes touring acts and residencies, a run of restaurants from a steakhouse down to a coffee counter, and a buffet that locals still argue about. The beach is directly across US 90 and public.
There is also golf, which is not here. Fallen Oak, the Tom Fazio course associated with the resort, sits inland at Saucier about half an hour north, and access has generally been tied to staying at the property. Check the current arrangement before you plan a round around it.
The constraint to understand in advance is age. Mississippi sets 21 as the minimum for gambling and for being on a casino floor at all, and in a building where the floor sits between the lobby and several restaurants, that shapes how a family moves around.
