The Key West Aquarium is one of America’s oldest aquariums, opened in 1934 as a Works Progress Administration project. Located at 1 Whitehead Street at Mallory Square, it has been a Key West family attraction for over 90 years. The 8-tank facility focuses entirely on Florida Keys native marine life — parrotfish, yellowtail snapper, sergeant majors, nurse sharks, southern stingrays, sea turtles, queen angels, and the occasional tarpon — rather than the global menagerie of mainland aquariums. The intimate scale (90-minute typical visit) and four-times-daily shark feedings make it ideal for families with kids ages 3-12. This guide covers everything visitors need to know — current 2026 admission pricing, hours, exhibit descriptions, feeding schedule, the 2-day re-entry policy that doubles the value, parking strategy, and accessibility notes. Written by Key West locals who recommend the Aquarium to first-time families weekly.
You will get current ticket prices ($22.56 walk-up adults / $20.30 online; $12.89 walk-up kids 4-12 / $11.60 online; under 4 free), the four daily shark feeding times (11 AM, 1 PM, 3 PM, 4:30 PM), the three sea turtle conservation tour times, the touch tank and Atlantic Shores Native Habitat details, the smart 2-day re-entry strategy, combo passes with the Shipwreck Treasure Museum next door, parking options, and accessibility notes.

2-Day Re-Entry: The Value Hack
Key West Aquarium tickets are valid for 2 consecutive days. This is the single most under-discussed feature of the Aquarium experience.
Strategy 1: Visit in the morning, leave when kids tire, return the next morning to catch missed exhibits or feedings. Same ticket, no extra cost.
Strategy 2: Time the visit to catch shark feedings on both days (4 daily). Watch the 11 AM Tuesday, return 1 PM Wednesday for a different feeding spot.
Strategy 3: Split the visit between adults-only morning (touch tank, exhibits) and family-with-kids afternoon visit. Same ticket.
Most travelers use the ticket only once and don’t realize the 2-day re-entry exists. Save your wristband and use it again the following day.
Hours and Best Times to Visit
Hours: 9 AM – 6 PM daily, 365 days/year.
Best times:
9-10 AM: Lightest crowds, freshest exhibit experience.
11 AM: First shark feeding (highly visible and family-friendly).
1 PM: Second shark feeding. Crowds peaking but feeding draws them.
3 PM: Third feeding plus 3:15 PM sea turtle conservation tour.
4:30 PM: Final shark feeding. Crowds thinning. Catch the last feeding then exit before sunset.
Avoid the 11 AM – 2 PM window during peak season (December-March) for crowds.
Shark Feedings (4 Daily)

Times: 11 AM, 1 PM, 3 PM, 4:30 PM.
What happens: A staff member feeds the resident sharks (nurse sharks plus others) and stingrays. The feeding lasts about 15-20 minutes with narration explaining shark biology, behavior, and conservation. Touch tank engagement often follows.
Best viewing: Arrive 10 minutes before feeding time to secure a spot at the railing. The 1 PM and 3 PM feedings are typically the most crowded.
Touch tank during feedings: Sometimes available. Staff allow gentle touching of nurse shark tails (not heads/sides).
Sea Turtle Conservation Tours
Times: 10:15 AM, 12:45 PM, 3:15 PM (typically 3 daily).
Format: 15-20 minute guided tour focused on the Aquarium’s rescued sea turtles. Past residents have included Rocky, Lola, Spike, and Hector. The Aquarium partners with the Florida Keys Sea Turtle Hospital for rehabilitation and education.
Best for: Older kids (8+) and adults interested in marine conservation.
Free with admission (no separate ticket).

Sea Turtle Stories

The Key West Aquarium partners with the Florida Keys Sea Turtle Hospital (in Marathon) for rehabilitation and education. Past resident sea turtles have included:
Rocky — A sea turtle with a buoyancy issue making him unable to dive (and therefore unable to be released to the wild). Lives at the Aquarium long-term.
Lola — A green sea turtle in long-term rehabilitation.
Spike — A loggerhead in recovery.
Hector — Various other rescued turtles cycle through.
The 3:15 PM Sea Turtle Conservation Tour covers each turtle’s story — what happened, why they’re at the Aquarium, and conservation efforts to protect wild populations.
Family Tips
Best for ages: 3-12. Older kids may find the visit short; younger toddlers may struggle with attention but enjoy the touch tank.
Strollers welcome.
Bathroom located inside the facility.
Gift shop: At the exit. Plush sea turtles, books, conch shells.
Combine with: Mallory Square Sunset Celebration after the 4:30 PM shark feeding. Walk over to Mallory Square (next door) for the sunset performers.
Pre-visit prep: Watch a Florida Keys reef video on YouTube before visiting. Kids who recognize species are more engaged.
History of the Key West Aquarium
Built 1932-1934 as a Works Progress Administration project during the Great Depression. The Aquarium was Key West’s first major tourism investment, designed to draw visitors during the economic downturn. Originally focused on regional Florida Keys species — and that focus continues today.
Renovations and expansions over the decades have added the touch tank, the Atlantic Shores Native Habitat, and updated displays. The original 1934 building structure remains, making the Aquarium one of America’s oldest continuously-operating aquariums.
What Locals Wish You Knew
The Aquarium is a favorite recommendation for families with kids ages 3-12. Locals wish more visitors knew:
Save your wristband for 2-day re-entry. The single most under-used feature.
Buy online for 10% discount. Walk-up pricing is significantly higher.
Time your visit for the 4:30 PM feeding then walk over to Mallory Square for sunset. The Aquarium-to-sunset combination is the perfect family afternoon.
The Atlantic Shores tank is the best photography spot. Wide-angle shots through the glass capture the rays and tarpon swimming together.
Touch tank rules vary by staff. Some allow more touching than others. Be polite and ask.
