You’re lying in bed, staring into a dark, pulsing blue. It’s not a TV screen. It’s the Indian Ocean. Every few minutes, a silver flash of a trumpet fish darts past your nose, separated only by a thick pane of glass. This is the reality of the Manta Resort underwater room, a three-story floating structure anchored about 250 meters off the coast of Pemba Island. Honestly, it’s a bit eerie at first. You realize you aren’t just looking at the ocean; you’re an exhibit inside it.
Most people see the photos on Instagram and assume it’s just a fancy hotel room with a view. It’s much weirder than that. Pemba is the quieter, wilder cousin of Zanzibar. While Zanzibar has the crowds and the spice tours, Pemba has the "Blue Hole," a circular depression in the coral reef where the Manta Resort decided to drop a literal house into the sea. It’s isolated. There’s no Wi-Fi out there. Just you, a kayak, and a lot of water.
Why the Manta Resort Underwater Room is Different from Dubai or Maldives
When people think of underwater hotels, they usually think of the Conrad Maldives Rangali Island or the Atlantis in Dubai. Those are feats of engineering—massive, concrete-reinforced tunnels or suites built into aquarium walls. They feel like high-end bunkers. The Manta Resort underwater room is a totally different animal.
Designed by Mikael Genberg of Genberg Underwater Hotels, the structure is a floating island. It’s made of local hardwood and Swedish engineering. It doesn't feel like a bunker; it feels like a raft that happened to grow a basement.
The top deck is for sunbathing and stargazing. The middle deck, at sea level, has your lounge area and bathroom facilities. Then you climb down a ladder into the bedroom. That’s where things get intense. Because the structure floats, it moves. You’ll feel the subtle sway of the tides. It isn't for people who get seasick easily, though the anchoring system is incredibly sturdy. You’re basically living in a buoy with a king-sized bed.

The Reality of Sleeping Four Meters Below the Surface
Let’s talk about the light. During the day, the water is a bright, piercing turquoise. You can see the reef fish—batfish, Spanish dancers, and the occasional octopus—going about their business. But the magic (and the slightly spooky part) happens at night.
The room has exterior spotlights under the windows. These lights attract plankton. The plankton attracts smaller fish. The smaller fish attract predators.
It’s not uncommon to wake up at 3:00 AM and see a squid staring back at you. Or a shy reef shark circling the perimeter. It’s a literal food chain happening inches from your face. Swedish artist Mikael Genberg, who also created the Utter Inn in a Swedish lake, wanted people to feel the "sublime" nature of the ocean. He succeeded. It’s silent down there, except for the muffled, rhythmic thumping of the ocean against the hull.
The room is part of a conservation effort too. The Kwanini Marine Conservation Area was established around the resort to protect the reef from dynamite fishing, which was a huge problem in the region. By staying in the Manta Resort underwater room, you’re essentially paying for the guards who patrol the reef to ensure the ecosystem stays intact. It’s a rare case where luxury tourism actually helps keep the local environment from collapsing.

What Most People Get Wrong About Pemba Island
If you're planning to trek all the way to Pemba, you need to know that this isn't a "polished" luxury experience. It’s "off-grid" luxury.
- The boat ride out to the room can be choppy.
- The bathroom is on the sea-level deck, so if you need to go in the middle of the night, you have to climb a ladder out of your underwater cocoon.
- Maintenance is a constant battle against salt and barnacles.
Pemba is one of the most fertile islands in the world, famous for cloves. The air smells like Christmas even in July. But the infrastructure is rugged. You fly into a tiny airstrip on a Cessna, drive through dense forests and villages, and eventually hit the northern tip where the resort sits. It’s a journey. If you want white-glove service where someone peels your grapes, go to the Maldives. If you want to feel like a pioneer in a Jacques Cousteau film, this is it.
The Logistics of Booking and Staying
You can't just book the underwater room for a week. Well, you could, but the resort usually recommends staying in one of their "land" villas first and then doing one or two nights in the underwater suite as a highlight. It’s expensive—usually hovering around $1,800 USD per night for two people.
Included in that price is a dedicated service team. They bring your meals out to you by boat. You can specify when you want to be left alone and when you want your sundowners delivered. Most guests spend the afternoon kayaking around the "Blue Hole" or snorkeling right off the deck. The reef edge is only a few meters away, dropping off into the deep dark blue.

One thing people rarely mention is the "fish-bowl effect." During the day, local fishermen might pass by in their dhows. They’re used to the room being there, but it’s a reminder that you aren’t in a private bubble; you’re in a living, working ocean.
Actionable Steps for the Aspiring Underwater Traveler
If you are actually serious about booking the Manta Resort underwater room, don't just wing it.
- Check the Moon Cycles: Seriously. A full moon provides incredible natural light for seeing the silhouettes of larger fish, but a new moon makes the artificial spotlights much more dramatic.
- Pack Light and Waterproof: You’ll be transferring from a beach to a small boat to a floating platform. Bring a dry bag for your electronics.
- Book 6-12 Months Out: There is only one underwater room. Just one. It’s often booked out a year in advance for honeymoons and milestone birthdays.
- Understand the "Pemba Shake": The small planes to the island have strict weight limits. Don't bring your massive hardside suitcase. Use a duffel.
- Engage with the Kwanini Foundation: Ask the staff about their conservation work. It makes the stay feel much more meaningful when you see the actual rangers protecting the waters you’re sleeping in.
The Manta Resort underwater room isn't just a hotel stay; it’s a psychological shift. You go from being a terrestrial creature to an observer of a world that usually ignores us. When the lights go out and you’re staring into the abyss of the Indian Ocean, you realize how small we really are. It’s humbling. It’s beautiful. And yeah, it’s a little bit terrifying. That’s exactly why it’s worth it.
