The Aquarium at Silverton Casino

The Aquarium at Silverton Casino is one of the rare Las Vegas outings where the headline number is zero. Admission is free, and the listing notes it was voted Best Free Attraction in Las Vegas. The tank sits inside the Silverton at 3333 Blue Diamond Rd in the 89139 zip code, and the aquarium is viewable 24 hours a day, seven days a week, year round. That around the clock access means it can absorb an odd schedule, a toddler who wakes at dawn, or a spare half hour before dinner nearby.

Two programs appear on the listing: live mermaid shows and a Mermaid School, where kids can learn to swim like a mermaid. There is also a Dive Ventures experience for certified divers recorded at $300, which is a separate paid add on rather than part of a normal visit. A gift shop rounds out the amenities alongside the aquarium and the live shows.

The listing's age range is 0 to 18, which is this directory's default range rather than a posted policy from the venue, though the brackets on file, 0 to 3, 4 to 6, 7 to 12, and 13 to 18, reflect that an aquarium viewing works for essentially any age. The listing also marks the venue as special needs friendly, though no specific accommodations are described, so ask directly if your child has particular needs.

One practical note a local parent would give you: the aquarium is inside a casino property, so you will walk through a casino environment to reach it. Plan your route with kids accordingly.

Google reviewers rate it 4.6 across 1,880 reviews, a solid average for a free attraction with heavy foot traffic. Programming is in English. For show times, Mermaid School details, or questions about the dive experience, call (702) 263-7777. Since viewing costs nothing, this is an easy first stop to test whether your kids are aquarium kids before paying for a larger attraction elsewhere.
