Get into the world's largest aquarium before public doors open, then go behind the glass with a whale shark encounter few visitors ever see.
What to expect
After a safety briefing and wetsuit fitting, you snorkel inside the Ocean Voyager tank alongside whale sharks, manta rays, and hammerheads, guided by aquarium biologists the whole time. Above water, the exhibit itself — one of the largest indoor aquariums on Earth — is worth lingering in afterward. It's equal parts marine biology lesson and adrenaline.
Good to know
Book the Gentle Giants encounter weeks ahead — sessions are limited and fill fast. Arrive 30 minutes early for the wetsuit fitting; the aquarium is a short walk from downtown hotels.
