St Thomas: Sea Trek Helmet Dive at Coral World Ocean Park

Summary

Walk beneath the waves at Coral World with a Sea Trek helmet dive and see St Thomas marine life up close

You’ll step into St Thomas’ clear waters with a Sea Trek helmet dive, walking along the ocean floor near Coral World Ocean Park. Feel fish brush past your visor, hear only your own breath, and surface with salty hair and wide eyes. Includes park admission and guidance from locals who know every curious creature down there.

What’s the experience like?

"Just keep walking, you’ll feel it click," our guide called out, voice echoing weirdly through the water as I shuffled forward. I’d never worn anything like this Sea Trek helmet before—felt a bit like an astronaut, honestly, except instead of floating off I was anchored to the sandy bottom near Coral World Ocean Park in St Thomas. The water pressed cool against my arms but my hair stayed dry inside the dome, which was almost stranger than breathing normally down there. Fish darted past my visor—one yellow guy in particular seemed determined to photobomb every shot.

I kept glancing at my friend to make sure she was okay (she gave me a thumbs-up so dramatic it made bubbles swirl). Our guide—can’t remember if his name was Marcus or Markel—pointed out a sea cucumber nestled by some rocks, then motioned for us to crouch down and look closer. The sand felt gritty under my fingers. It’s funny how quiet everything gets once you’re under; just your own breath and the faint hum of the air in your helmet. Didn’t expect to feel that calm, honestly.

After about 25 minutes underwater we surfaced near the Underwater Observation Tower, blinking in the sunlight like we’d come back from another planet. My legs felt wobbly but in a good way—the kind you get after doing something new. We hung around Coral World for a while after (entry’s included), still dripping saltwater and grinning at each other. I still think about that one fish with the big eyes staring right back at me—you know when something just sticks in your head?
