The excursion

Robinson Island Glass Bottom Boat Tour

That is the appeal of a Robinson Island glass bottom boat tour from Diani Beach. The excursion combines coastal scenery with an opportunity to view marine life through a glass bottom boat, with snorkelling available on some packages. The sandbank known locally as Robinson Island emerges with the tide and is not a permanent island.

Plentiful Adventures can help you enquire about arranging this coastal experience, with the final itinerary, price and inclusions confirmed before booking.

What makes Robinson Island special?

Robinson Island is the local name used for a tidal sandbank off Diani Beach. The boat journey takes visitors over shallow coastal waters towards the reef and sandbank area. The precise duration, route and stop depend on the operator and sea conditions.

It is a good option to consider if you want to experience the coast from the water rather than spend the whole day on the beach.

What to expect on the excursion

1. A glass bottom boat ride

Enjoy views of the water beneath the boat as the crew navigates the coastal area. Depending on underwater visibility, you may be able to see fish, coral and other marine features through the viewing panels.

Visibility varies with weather, tides, water movement and local conditions, so particular sightings cannot be guaranteed.

2. A possible snorkelling stop

Some Robinson Island packages combine the glass bottom boat ride with snorkelling. This gives confident swimmers an opportunity to explore the water more closely when conditions allow.

Before booking, confirm whether snorkelling equipment, guidance and any required fees are included. Follow the crew’s instructions, wear appropriate flotation or safety equipment, and never touch or stand on coral.

3. Time on the tidal sandbank

When the tide allows, the sandbank can offer a memorable place to pause, enjoy the ocean views and take photographs. Its size and accessibility change with water levels, so the stop is dependent on the tide and cannot be guaranteed at every departure time.

4. Coastal photography

The combination of the boat, reef scenery, open water and exposed sand can provide excellent photography opportunities. Protect phones and cameras from saltwater, and follow the crew’s instructions about where it is safe to move around the boat.

Is this trip suitable for people who cannot swim?

A glass bottom boat ride can be an option for people who prefer to stay aboard and view the marine environment without entering the water. Some operators explicitly market their glass bottom boat experience to families and people who cannot swim.

However, snorkelling and swimming are separate activities. Tell the operator if anyone in your group cannot swim, has mobility needs or is travelling with young children, and confirm the safety arrangements before booking.

When is the best time to go?

The tide is an important factor because the sandbank is exposed only during part of the tidal cycle. Operators may adjust departure times to align the excursion with the expected water levels.

Ask for the confirmed departure time for your chosen date instead of assuming that every trip leaves at the same hour. Sea conditions and underwater visibility can also affect the experience.

What should you bring?

  • Swimwear and a towel if you intend to swim or snorkel.
  • Sunscreen, sunglasses and a hat.
  • Water friendly footwear.
  • A waterproof bag for valuables.
  • Drinking water, according to your operator’s guidance.
  • Any personal medication you may need.

Confirm whether the boat operator provides snorkelling gear, life jackets and refreshments, as these inclusions differ between packages.

How much does the Robinson Island tour cost?

The price depends on the operator, group size, transport arrangements and activities included. Published offers differ, so ask Plentiful Adventures for a current quote rather than relying on another operator’s advertised price.

Before confirming, ask whether the package includes hotel pickup, the glass bottom boat ride, snorkelling equipment, a guide, refreshments and any applicable fees.
