Lumina is the name given to the fountain in the main Porte Corchere of Aria. Although certainly not as grand as the one at Bellagio, it is still nevertheless impressive, with intricately timed bursts of water lit with neon colors that are visible even during the day. Of course nighttime really brings out the splendor here, with the dancing waters and colors looking like brightly colored fountains of paint arcing, colliding, and exploding.

Lining the curved wall of Aria is Focus, a 270 foot long waterfall of sorts that flows down into a shallow reflecting pool. The water can be timed to go in sheets, at angles, or in other designs.

In the Crystals mall two additional features take water in new directions.

Halo, located in the center of the mall on the first level, is a series of crystal tubes, each with its own vortex of water lit in various bright colors. The tubes sit at angles, which forces the mini water-spouts to twist and turn as they naturally want to right themselves. WET bills this as their first water feature that guests can actually go inside of with walking space between and above the tubes.

Glacia is located at the front of the Crystals at the entrance from The Strip. This one features 15 columns of solid water, otherwise known as ice. Each is formed overnight and then rise up out of a shallow pool and are randomly carved on the way up. Then they melt. It doesn't sound like much, but the endless combinations of shapes, sizes, and textures (the ice can be clear, cloudy, or opaque) and the unpredictable ways in which they melt make this an ever changing icy sculpture garden of sorts. Note the background music: it was composed by Grateful Dead drummer Mickey Hart.

All of the water features are accessible to the general public (mall operating hours only for Glacia and Halo) and there is no charge to view them.
