Miami Seaquarium Closes; New $100 Million Marina Plans Unveiled

UPDATE: The iconic Miami Seaquarium has officially closed its gates on October 12, 2025, after serving as a tourist attraction for 70 years. As the park transitions to new ownership, developer David Martin is set to launch a transformative project that could reshape the Virginia Key waterfront.

The Seaquarium’s closure comes amidst a complex bankruptcy process, with Martin planning to invest upwards of $100 million into a new marina and entertainment complex. This urgent redevelopment is aimed at revitalizing the site, which is currently owned by Miami-Dade County.

During a recent tour of the property, Martin outlined an ambitious vision that includes a state-of-the-art aquarium complex and a scenic baywalk promenade featuring a restaurant hub inspired by the proposed Fishermen’s Village. The centerpiece of his plan—a large marina with piers and floating docks—aims to be the primary revenue generator, offering visitors a fresh waterfront experience.

“We’re looking at creating an all-weather event space under the iconic gold geodesic dome,” Martin shared. “We want to ensure that our offerings are both accessible and cater to upscale dining experiences.”

The Seaquarium’s current marine life, including dolphins and sea lions, must be relocated before Martin takes control of the lease, which is pending approval from a bankruptcy judge. His proposed $22.5 million bid is considered the best option for the financially strapped Dolphin Company, the Seaquarium’s former parent organization.

As Martin prepares for this transition, he has received backing from key officials including Miami-Dade Mayor Daniella Levine Cava, who has advocated for the Seaquarium’s closure due to alleged animal mistreatment, and Commissioner Raquel Regalado, who represents the Virginia Key area.

Martin’s plans not only focus on commercial success but also on educational initiatives, including a partnership with the University of Miami for coral conservation education. “We’re excited about the potential for a nature center that enriches marine education,” he stated.

Environmental considerations are also at the forefront of Martin’s strategy. He is consulting with experts on low-impact dredging techniques to minimize ecological disturbances as the marina takes shape. “We’re committed to optimizing the marina’s design while protecting local seagrass habitats,” he emphasized.

This redevelopment marks a significant shift for the area, moving from a traditional theme park to a vibrant marina and entertainment hub. Martin, who is also involved in other substantial developments across Miami, is determined to retain the Seaquarium brand while ensuring that the site remains a destination for families and marine enthusiasts alike.

As the project progresses, the community will be watching closely. The transformation of the Seaquarium could redefine how Miami engages with its waterfront, integrating leisure, education, and environmental stewardship into one of the city’s most cherished locations.

For those eager to see what the future holds, the coming months will be crucial. Approval from Miami-Dade County is expected soon, and Martin’s ambitious plans could soon become a reality, reshaping the former Seaquarium into a thriving marina and public space.
