Diani Glass-Bottom Boat Ride to Robinson Island

The Diani glass bottom boat trip to Robinson Island goes over the reef to the Robinson Island sandbank for snorkelling and swimming, for KES 2,000 per adult with a Kenyan ID or USD 40 per international adult.

If you book outside that window, you can miss the landing or sit in poorer water. Use listed-price booking so departure is timed to the tidal calendar rather than a broker guess on the sand.

Booking with Diani Excursions Office ensures your trip is scheduled correctly within this window. Unregistered beach operators can misjudge the tides, leading to a missed landing or navigating rough water as the sandbank disappears under two metres of ocean.

Diani Glass Bottom Boat Trip Step by Step

The excursion begins from a designated departure point along Diani Beach. On board, large glass panels in the boat's hull allow you to observe the marine ecosystem below, including various corals and reef fish, without entering the water. The sandbank that boat crews call Robinson Island Diani appears only around low tide.

As the tide recedes to its lowest point, the boat moves towards the emerging sandbank. The crew anchors nearby, so you can disembark to walk on the pure white sand, surrounded by clear ocean. You will have a set period here to swim and take photographs before the tide begins to rise again, after which the boat returns to shore.

Diani Sandbank Trip for Families and Non Swimmers

This trip suits a wide range of travellers because of its relaxed nature. The activity is an excellent choice for families with young children, who can experience the underwater world safely from the boat. It is also suitable for non-swimmers who wish to see marine life without snorkelling.

Couples and small groups looking for a short, scenic marine outing will find the sandbank visit offers a memorable experience. The setting provides fantastic opportunities for photography in an environment that only exists for a few hours each day.

Tide Windows for the Diani Sandbank Trip

The Diani sandbank is not a permanent island; it is a sand formation exposed only during low tide. The timing of low tide changes daily according to the lunar cycle, which creates a narrow and predictable window for any visit. Reaching the sandbank outside this window is either impossible or unsafe. Read how Diani tides change boat times and snorkelling visibility before you pick a date.

Booking with an operator who does not schedule trips according to the official tidal calendar carries a significant risk. You may arrive to find the sandbank is still submerged or that you have very little time before conditions become unsafe. Diani Excursions Office plans every sandbank trip to coincide with the low tide, ensuring you have a safe and complete experience.

Getting to the Diani Glass Bottom Boat Departure Point

Our listed packages for the sandbank excursion include return transport from any hotel, resort, or private villa in the Diani Beach and Ukunda area. This service removes any uncertainty about finding the correct departure point along the coast.

Once your booking is confirmed, our office will contact you to arrange the specific details for your collection. A driver will meet you at your accommodation at the agreed-upon moment, ensuring you arrive at the boat in good time for a departure that aligns with the day's tides.

Diani Sandbank Trip Safety Rules

All our vessels are equipped with life jackets for every passenger, and the crew provides a safety briefing before departure. You must follow the captain's instructions at all times, especially when moving around the boat or disembarking at the sandbank. See what to wear on a glass bottom boat, including reef shoes for the sandbank.

We encourage responsible tourism to protect Diani's marine environment. Please use reef-safe sunscreen to avoid damaging the coral. Do not touch or stand on the coral reef, and do not remove any shells, coral, or marine life from the ocean. These conservation principles are important for preserving our local reefs.

Diani Sandbank Trip Key Facts

Diani Glass Bottom Boat Price

The Diani glass bottom boat costs KES 2,000 per adult and KES 1,000 per child under 12 for Kenyan ID holders (citizen rate), or USD 40 per adult and USD 25 per child under 12 for international visitors. The price includes the glass bottom boat ride, snorkelling and swimming at Robinson Island.

Add a Robinson Island photo shoot on a clear kayak or boat, with drone shots and a set of photos and videos, for KES 12,000 or USD 120 per session.

How Long You Get on the Sandbank

The sandbank is only above water around low tide. The landing window lasts about three hours, centred on the lowest point of the tide, and low tide comes about 50 minutes later each day, so the boat time changes daily. A typical stay on the sand is one to two hours before the water returns.

Avoid trips timed for mid tide. The sandbank is then half covered or being covered, the water is often cloudier and currents are stronger, so the landing can be cut short.

Why Your Pickup Time Changes With the Tide

Because the trip follows the tide, we confirm your exact pickup time on WhatsApp on the morning of the trip. Keep your phone on, and do not book the boat on a flight, airport transfer or checkout day, because the time can move by an hour or two.

Glass Bottom Boat Trips for Non-Swimmers

You do not need to swim to enjoy the trip. You can watch the reef through the glass panel and stay dry, and every passenger gets a life jacket and a safety briefing before departure.

If you snorkel, test the mask before you set off: hold it to your face without the strap and breathe in gently through your nose. If it stays in place, it seals. Bringing your own silicone mask is the easiest way to avoid leaks.

What the Boat Price Does Not Cover

Food and crew tips are not part of the boat price, and tipping the crew is up to you. Bring reef-safe sunscreen, a hat and reef shoes for the sandbank.
