Deep Sea World Aquarium

Perched at Battery Quarry in North Queensferry near Edinburgh, Deep Sea World is a PADI 5 Star Dive Center where the invitation is simple: why not spend a day at the bottom of the sea? This purpose-built facility lets you walk beneath the water through the UK's longest underwater tunnel, surrounded by huge sharks, tropical fish and a myriad of marine life.

What you'll find here

The residents are the real draw — fascinating Sand Tiger sharks, conger eels, whales, turtles, rays and Stella the stingray all share these waters. As a PADI Scuba Diving centre and purpose-built facility, it pairs its aquarium and deep pool with genuine conservation activities, so diving here comes with a wider marine focus.

With parking on site and English spoken, Deep Sea World suits divers and curious first-timers alike who want to see the wonders of the deep up close. It's open through the week from 10:00 AM to 05:00 PM, with slightly later Sunday hours from 11:00 AM.
