The Aqua Marine Park (tunnel aquarium) in Hyderabad will be India’s largest project that will be built with Rs. 300 crores. 

With over 2,50,000 sq. ft built-up area, this tunnel aquarium will come up in the Kothwalguda Eco Park, spread over 4.27 acres. 

The curved tunnel will be at least 100 metres with a 3.5-metre walkway and a 180-degree view.  

"We are also exploring options to set up such multiple tunnels,” said an official from the Municipal Administration and Urban Development (MA&UD) Department. 

This Aqua Marine Park will have tunnels with various aquamarine species, including fish, reptiles etc. 

It will also have a restaurant with a view of exhibits/panel displays, a dome theatre, a virtual aquarium, touch tanks and interactive kiosks for children.  

India’s biggest tunnel aquarium will have a minimum capacity of around 2,500 people.
