Sea Trek Helmet Dive at Coral World: Walk Underwater Easily

Your head stays dry and you breathe normally while walking upright on the seafloor.

Sea Trek is an underwater helmet diving activity at Coral World Ocean Park in St Thomas where you walk along a marked trail on the ocean floor while wearing a weighted helmet that supplies air and keeps your head completely dry. The 45-minute program includes about 25 minutes underwater, a guide-led orientation, and free admission to Coral World. Children must be at least 8 years old and weigh at least 80 pounds.

The experience

You arrive at Coral World Ocean Park and head straight to the Sea Trek station: no certification courses, no prerequisites beyond the ability to walk and breathe normally. After a brief orientation, your guide fits you with the helmet, which supplies air from the surface and provides the weight and stability to keep you upright on the seafloor. The helmet seals around your neck. Your head and hair stay completely dry inside it, and you breathe like you would on land.

The guide leads you along an underwater trail near Coral World's Underwater Observation Tower. Fish and other sea creatures swim right up to your visor as you walk. The weightlessness of moving underwater without the bulk of scuba gear means you can turn, crouch, and explore without fighting the equipment. About 25 minutes of the 45-minute program happens underwater. The rest is orientation, suiting up, and getting back to the surface.

Free admission to Coral World is included with your Sea Trek booking, so you can spend time in the park before or after your dive: the observation tower, the touch pools, and the rest of the exhibits are yours to explore on the same day.

Top questions

Can children come?

Yes. Ticket types: Child (8 to 12 years). Children under 8 can't be included in the booking.

What happens if it rains?

It may be canceled due to bad weather. If that happens, you're offered another date or a refund. No refund if you cancel.

What's the difference between Sea Trek and regular scuba diving?

Sea Trek requires no training or certification. If you can walk and breathe, you can do it. You walk upright on the seafloor in a helmet that supplies air from the surface, rather than wearing tanks on your back and managing buoyancy underwater. Your head stays dry and you breathe normally, not through a regulator.

Will my hair and head get wet?

No. The helmet seals around your neck and keeps your head and hair completely dry. You breathe normally inside it, and the air comes from the surface through a hose.

How long do I actually spend underwater?

The total program is about 45 minutes, with approximately 25 minutes spent walking on the seafloor. The rest covers orientation, getting into the helmet, and returning to the surface.

What should I bring?

Wear or bring swimwear with a cover-up and a towel. You'll change into your swim clothes before the orientation, and you'll want to dry off afterward.

Is Sea Trek included with Coral World admission, or do I need to buy both?

Sea Trek is a separate activity you book independently. Free admission to Coral World Ocean Park is included in your Sea Trek booking, so you don't pay entry separately.
