Worth it? NO — it is CLOSED. This is a hard "skip": the Miami Seaquarium ceased operating Oct 12, 2025 and cannot be visited. Beyond closure, its final decades drew sustained animal-welfare criticism (USDA violations; the 2023 death of the orca Lolita/Tokitae) — a history we report honestly rather than nostalgically. For marine life on the island, point readers to the Biscayne Nature Center's seagrass program and the parks instead.
Who it’s NOT for: Everyone, for now — the Seaquarium is permanently closed (Oct 2025); there is nothing to visit. A future non-marine-mammal aquarium is planned but not built. Anyone told (by an old guidebook/listing) that it's a Key Biscayne must-do — that information is stale; correct it.
Skip it if: Always, until/unless the planned replacement aquarium opens (no timeline as of 2026). If a reader asks, the honest answer is: closed — visit Bill Baggs, Crandon, or the Nature Center instead.
Time needed: N/A — closed. (Formerly a half-day attraction.)
Best time: N/A — closed permanently since Oct 12, 2025.
Cost: n/aBooking: N/A — closed. Redirect readers to open island nature: Bill Baggs, Crandon Park, the Biscayne Nature Center's seagrass wade, or a mangrove kayak.
