7. Bellagio Conservatory & Botanical Gardens
The Bellagio Hotel & Casino (address and info)
Remember, this isn’t your ordinary conservatory -- this is Vegas. The setup at the Bellagio changes about five times a year, as they put on full floral productions inspired by the seasons as well as the Chinese New Year, creating ridiculous displays in the 14,000sq ft space under the glass skylight. Its current summer theme is inspired by the deep sea, touting a mermaid with 1,500 flowers in her tail, jellyfish hanging from the ceiling, and a sea turtle with carnations making up its shell.
