See the reef and its fish without getting in the water — a glass-bottom boat, a real submarine dive with Blue Safari, or a helmeted walk on the sea bed. None require swimming, which makes all three a common pick for families with young children and for non-swimmers. Below: verified operators by region, each with a contact we sourced ourselves, and any age or health detail only when the operator itself publishes one.

For whom?
All three activities are built for non-swimmers and families — nobody needs to put their face in the water. The one operator here that publishes specific age and health guidance is Blue Safari, for its submarine and subscooter: the submarine accepts children from 9 months (useful for ear equalization at the end of the dive) and is not recommended for severe claustrophobia or heart problems, though pregnant women can ride; the subscooter requires a minimum age of 8 and is not recommended during pregnancy or for severe eardrum, asthma or cardiovascular conditions (blue-safari.com, consulted 2026-11-06). No other operator below publishes this level of detail — ask directly if a health condition applies to your group.
No. A glass-bottom boat, the submarine and the undersea walk all keep you dry (the undersea walk uses a sealed helmet fed with air from the surface) — none of them require swimming, making them a common choice for non-swimmers and young children.
What's the difference between the three?
A glass-bottom boat stays on the surface, looking down through a viewing window — no special conditions beyond being on a boat. The submarine (Blue Safari) actually submerges, with passengers seated behind portholes. An undersea walk has you walk on the sea bed in a helmet that keeps your head dry while you breathe normally, no diving training needed.
Is there a minimum age or health restriction for the submarine?
Blue Safari's own FAQ (consulted 2026-11-06) states a minimum age of 9 months for the submarine and 8 years for its subscooter, and advises against the submarine for severe claustrophobia or heart problems — pregnant women can ride if they wish. See the "For whom?" section below for the full detail and source. We only show an age or health claim when the operator itself publishes one; ask the others listed here directly.
Where can I do this in Mauritius?
DivingMauritius lists verified operators in 3 regions — the east coast (Belle Mare) has the most glass-bottom and undersea-walk operators, the submarine departs from the north-west (Trou aux Biches).
How do I book?
Contact the operator directly using the sourced phone, WhatsApp, email or website on its card — DivingMauritius does not take bookings.
