Wonder and whimsy are hallmarks of Cirque du Soleil. Add in the element of water and you’ve got “O” (Bellagio, 702.693.8866), a one-of-a-kind spectacle that can only be seen in Las Vegas.

Many consider “O” to be the crown jewel of entertainment on the Strip. The signature production at Bellagio has been thrilling audiences for more than 20 years and, with thousands of performances already in the books, it shows no signs of slowing down.

The technical wizardry of “O” remains unmatched to this day. Bizarre, colorful characters arise from the depths of a pool in the center of the stage and sail through the air on elaborate devices that make the impossible seem real. Yet it’s the dazzling artistry of its performers that gives the production its heart.

Through dance, diving, water ballet and amazing acrobatic feats, an international cast of 85 celebrates the most vital element of life. Visual poetry fills a huge stage where carousel horses drift by and umbrellas float on the water. The effect is visceral, touching emotions in a way that’s impossible to resist. You may not be able to describe what you’ve seen, but you’ll never forget the magic of “O”.

Bellagio, 7 & 9:30 p.m. Wed.-Sun., $98.50-$155 plus tax and fee. 702.693.8866
