Underwater hiking: an activity accessible to all

How it works

Underwater hiking involves walking along the bottom of the lagoon with a helmet on your shoulders, supplied with compressed air. You descend a ladder from the boat, place your feet on the sand at a depth of 3 meters, and walk freely among the corals and fish, your head above water thanks to the helmet, while being completely submerged.

You breathe normally, as if you were in open air. No breathing techniques to master, no mask on your face, no stress related to water in your eyes or nose.

The advantages

• No experience required : you just need to be able to walk

• No swimming skills required : ideal for non-swimmers and apprehensive individuals.

• From age 6 and up : the most inclusive activity in the lagoon

• State-certified guide by your side underwater : maximum safety at all times

• Direct contact with marine wildlife : you walk among the fish, you can hand-feed them, and the stingray often comes to visit you.

• High-definition souvenir photos taken by your guide

The limits

• Depth limited to 3 meters: you will not have access to the deep sea.

• Reduced mobility compared to freediving: you walk, you don't swim

• Guided activity with a set schedule: less freedom than solo snorkeling

For whom?

Underwater hiking is the ideal choice if you cannot swim, if you are travelling with children or seniors, if you are apprehensive about putting your head underwater, or if you are looking for a guided and safe experience with privileged contact with marine life.

Snorkeling: freedom on the surface

How it works

Snorkeling involves swimming on the surface, with your head underwater, equipped with a mask and snorkel. You observe the seabed from the surface, occasionally diving down to get closer to what interests you.

The advantages

• Great freedom of movement : you go wherever you want, whenever you want.

• Easy to practice for all swimmers, even without prior experience

• Ideal for exploring the lagoon at your own pace , especially from the overwater bungalows.

  
  

The limits

• Knowing how to swim is essential : without it, snorkeling is dangerous.

• You're staying on the surface : the most beautiful fish and the densest corals are often found in the depths.

• A less immersive experience : you observe marine life from a distance, without really being in it.

• Depending on visibility and sea conditions: a slight swell can be enough to disturb the water

• Most packages do not include an underwater guide : you are solely responsible for your own safety.

For whom?

Snorkeling is perfect if you're a good swimmer, looking for a relaxed and unstructured activity, and simply want to observe marine life from the surface. It's also a great option to complement another, more immersive activity.

Scuba diving: for explorers of the deep sea

How it works

Scuba diving allows you to descend to depths of between 5 and 20 meters, equipped with a wetsuit, mask, fins, and an oxygen tank on your back. It comes in two forms: introductory dives (accessible without certification, supervised by an instructor) and certified dives (for divers holding a PADI, CMAS, or equivalent certification).

In Bora Bora, diving offers access to exceptional dive sites: the Anau drop-off, shark passes, manta rays... We also offer this service with Bora Ocean Adventure

The advantages

• Access to the deep sea and to biodiversity inaccessible on the surface

• Spectacular encounters : lagoon sharks, manta rays, barracudas, turtles

• An intense and memorable experience for thrill-seekers

• On-site training is available, including a guided introductory session led by a certified instructor.

The limits

• Knowing how to swim is essential and a certain level of comfort in the water is recommended.

• Techniques to master : ear equalization, bottle management, balancing

• Medical contraindications : asthma, heart problems, pregnancy

• Minimum age of 8 years for a first dive, 12 years for certified diving

• Not accessible without certification for independent diving

For whom?

Scuba diving is for experienced swimmers who wish to explore deep waters, have access to pelagic species (sharks, manta rays) and live a more technical and engaging experience.

Our verdict: which activity should you choose based on your profile?

You can't swim → Underwater hiking

This is the only one of the three activities that doesn't require swimming skills. No other option will allow you to safely descend below the surface of the lagoon.

Traveling with children? → Underwater hiking

Accessible from age 6, supervised by state-certified guides, with no stress from getting water in your face — it's the perfect family activity in Bora Bora. Children love hand-feeding the fish.

You're on your honeymoon → Private underwater hike

Aqua Safari's private tour is the perfect romantic getaway: just the two of you, a dedicated guide, in the tranquility of the Bora Bora lagoon. An experience that couples describe as the highlight of their stay.

Are you a good swimmer? → Snorkeling or Scuba Diving

If you are a confident swimmer and prefer to explore at your own pace without a set schedule, snorkeling from your bungalow or during a boat trip is an excellent option: a complement to underwater hiking.

Are you a certified diver or looking to explore the deep sea? → Scuba Diving

If you have your certification and dream of swimming with sharks or manta rays in open water, scuba diving with our partner Bora Ocean Adventures is for you.

You want to do everything → Combine!

You can easily combine underwater hiking in the morning with snorkeling in the afternoon, or even try scuba diving as an addition. Many of our clients enjoy multi-day activities: Bora Bora is perfect for this.

The question we are asked most often

"Do you see as much while snorkeling as you do while scuba diving?"

The honest answer: not the same things, but often more things up close. At 3 meters deep, in our coral garden, you'll be surrounded by fish: they're within easy reach, curious, and accustomed to human presence. The stingray that circles you is an experience many certified divers have never had so close.

Diving provides access to other species (sharks, manta rays, deep-sea fish) but requires going deeper and mastering techniques that can reduce mental availability to simply observe and marvel.

The two activities are complementary, not competitive.
