Sea Walking at the Largest Pontoon of South East Asia (Borneo Reef World)

Have you ever imagined walking under the sea without gill? Well, it is not a dream, you don’t even need to know how to swim or have special skill such as scuba diving. I had tried sea walking last week at Borneo Reef World, the largest reef activity pontoon in Southeast Asia (second largest on the world). This pontoon is a floating platform on the sea off Sapi Island of Kota Kinabalu (KK), Sabah, Malaysia.

There are a few fun stuffs to check out on this pontoon. Let’s start with their Underwater Observatory.

Underwater Observatory

Just follow the staircase that leads to the bottom of the deck and you would be greeted by hundreds of reef fishes living in Tunku Abdul Rahman Marine Park.

The Underwater Observatory is a 20-Meter air-conditioned walkway about 4 Meters under the sea.

So who is in the “fish tank”? Fishes or people?

Sea Walking

Sea Walking (or Helmet Diving) is the highlight of my tour. Though I am a scuba diver, I wonder if the feeling is the same in sea walking.

briefing before sea walking
Pic: Briefing before the sea walking. This activity is so safe that even non-swimmers can join. A few staffs will follow you into the water and watch your every steps. The sea walking is carried out 5-Meter underwater for 20 minutes (Fee: RM150 ? USD50).

entering the water
Basically, they just put a helmet over your head, and a long (yellow) pipe, which provides oxygen, is connected to this helmet. When you walk deeper into the sea, you will feel a bit of discomfort in your eardrum in the beginning, due to increased water pressure. Just pause once in a while, equalize (as instructed in briefing) and let your ears adapt, and you shall be fine to proceed. Scuba divers can dive more than 20 Meters deep without problem, so 5-Meter is… nothing. Just go slow and don’t be panic.

Walking with this helmet under the sea was like having an adventure in outer space and Abyss. The feeling is funny in the water with dry head. Don’t worry, the helmet won’t float away.

There were schools of fishes swimming around me, so close that I could almost touch them. It was very quiet under the ocean. All I heard was the bubbling from my helmet. We couldn’t hear one another talking too.

Hey, someone shit on her helmet!

sea cucumber
Just kidding, it is a sea cucumber.

This sea cucumber turned long in lady’s hand. Don’t know why..

To keep our eyes and hands busy, the staffs brought us some coral and sea cucumber for a touch & feel experience.

The snorkeling mask, fins and life jacket are provided onboard, so you can snorkel in the sea near Sapi and Gaya islands.

brain coral
The corals there are in ok condition and I saw many colorful fishes. The day was cloudy so the visibility was poor underwater that day, otherwise I would have gotten better photos.

If you really love watersport, you may join their Discovery Scuba Diving, which requires no open diver license.

The Pontoon

The reef activity pontoon of Borneo Reef World is 880 Square Meters in size and 37.35 Meters in length. It can accommodate up to 500 people onboard. Personally, I think it’s the most suitable for a group of 100 people to have a private party. The pontoon has 3 levels, i.e., underwater observatory, lower deck and upper deck.

The pontoon is stable (in case you are prone to seasick) and built with high marine grade rust-proof aluminium. There are already some pontoons operate in Great Barrier Reef of Australia. I’m happy that Sabah has the largest pontoon in South East Asia.

  1. What happened to not disturbing the environment by not touching anything. Letting guest touch anenome, might as well give them jelly fish to touch. That would be more fun. Keep this up and there will not be anything left to see

    1. Hi Chris, thank you for your comment. Just to clear the misunderstanding. This pontoon is environmentally friendly and the operator also contributes to the conservation (e.g. coral planting) of the marine park. Please read more at:

      IMHO, touching the sea cucumber and anemone is no big deal and I view it as an awareness programme. Besides, many places have Touch Tank that allows tourists to touch the marine lives, and no environmental body complains that such practice hurts the animals.

  2. Hi dear,

    I’m first time visiting Kota Kinabalu.
    I’m so interested into the sea-walking activity and snorkeling at Pulau Sapi. I read the comment from internet, Pulau Sapi have less visitor thus it is more clean.

    My question is simple, is the sea-walking package come with snorkelling? Recently I saw a promotion in groupon which cost RM220 for an adult for under sea walking, im not sure it is worth to buy. Looks expensive to me tho.

    1. Hi Quinnie, the standard price of sea walking is RM295, so you got a good deal. Normally sea walking package includes snorkeling. However, you better check with your agent just to be sure.
