Shark Reef Aquarium Halloween: 2023 Hallow-Reef Event

Halloween is a holiday for everything spooky! Make it extra special with this year’s Shark Reef Aquarium Halloween 2023! Also known as the Hallow-Reef Event, the Shark Reef Aquarium at Mandalay Bay! 

Enjoy the extended hours in the exquisite aquarium as your adorable children scatter around with excitement in their costumes! Marvel in the wonders of the Shark Reef Aquarium’s rare underwater friends! 

Not only does Mandalay Bay’s Aquarium provide special views of over 2,000 species, but it also promotes Red Cross Donations by hosting a blood drive! Become a good samaritan and spooky ghoul this Halloween at Mandala Bay! 

A Gathering of Exotic Animals

Mandalay Bay is more than just pomp and circumstance. All of the animals residing in the Shark Reef Aquarium are protected and promoted for conservation! The aquarium itself recycles exhibit lighting to LED, water, and sustainable seafood for its residents!

The goal of the Shark Reef Aquarium is to promote the breeding of these unique and endangered animals, help marine biologists learn more about sharks, and rescue rare sea turtles!

Have your family learn more about animal breeding and witness the majestic exotic fishes available for viewing in the aquarium. Visit the glass tunnel that has its audience marveling as the animals swim above and around you!

Do you want more than just the fish and the sharks? Not to worry! Because Shark Reef Aquarium is home to one of the rarest species on the planet: a Komodo Dragon! 

Feeding the Animals

As fun as it sounds, feeding a komodo dragon is a dangerous activity. However, the aquarium does allow people of all ages to feed their other more friendly residents! 

Why not have you and your children experience feeding a real-life stingray? If you’re up for it, you can even feed the sharks on the reef themselves! 

Don’t worry too much about getting drenched in aquarium water, especially if you plan on feeding the turtles instead!


Tourists will have no trouble finding this iconic jewel of Las Vegas! That’s because Mandalay Bay Shark Reef is in one of the most well-known hotels on the strip! 

Mandalay Bay is a 43-story hotel located at the heart of the strip. MGM Resorts International owns the hotel, making it a safe place to book if you want to spend more time there!
