Ask anyone in Muscat where to go snorkelling and you will get the same answer: the Daymaniyat Islands. They are the benchmark every other spot in Oman gets measured against — and after running boats out there nearly every day, we still haven't found anywhere that beats them. This guide covers everything we get asked at the marina: where the islands are, how to reach them, what you'll see, when to go, what it costs and what to bring.
Where Are the Daymaniyat Islands?
The Daymaniyat Islands (also written Ad Dimaniyat) are a chain of nine small limestone islands in the Sea of Oman, lying roughly 18 km off Oman's Al Batinah coast, between Muscat and Barka. Declared a nature reserve in 1996 — the first marine nature reserve in Oman — they are protected by the Environment Authority for good reason: the surrounding reefs hold some of the healthiest coral in the Arabian Peninsula, and the beaches are among the region's most important nesting sites for hawksbill and green sea turtles.
Because the islands sit well offshore, the water around them is clearer than anywhere on the mainland coast — visibility of 10 to 20 metres is normal on a good day. That distance is also why you cannot simply drive there: every visit happens by boat.
How Do You Get to the Daymaniyat Islands from Muscat?
There is no ferry or public boat service to the Daymaniyat Islands. The only way to visit is with a licensed tour operator, and the trip works like this:
- Book a tour — either a shared snorkelling trip or a private charter.
- Meet at the marina. Our boats depart from Al Mouj Marina, Street 6, Muscat — about 15 minutes from Muscat International Airport.
- Cruise out. The crossing takes 35 to 45 minutes depending on the sea, and dolphins frequently join the boat on the way.
- Snorkel two to three different sites around the islands, chosen on the day for conditions and visibility.
Departing from Al Mouj Marina on Muscat's west side puts you on the correct side of the city for the islands — it is one of the closest departure points to the reserve, which means more time in the water and less time commuting across the sea.
What Will You See Snorkelling the Daymaniyat Islands?
Sea Turtles
Hawksbill and green sea turtles live around the islands year-round, grazing on the reef and surfacing to breathe right next to snorkellers. Seeing at least one turtle is the norm rather than the exception on our trips — many guests lose count.
Whale Sharks
From roughly August to November, whale sharks — the largest fish in the sea, and completely harmless — pass through the waters around the Daymaniyats. Swimming alongside one is an experience people fly across the world for, and in season the Daymaniyats are one of the most reliable places in the Gulf to do it.
Coral Reefs and Everything That Lives on Them
The reserve protects dense gardens of hard and soft coral that host hundreds of species of reef fish: parrotfish, angelfish, clownfish, fusiliers, snappers and clouds of sergeant majors. Look closer and you'll find moray eels, rays gliding over the sand, cuttlefish, and the occasional harmless blacktip reef shark patrolling the drop-off.
The Daymaniyats are the kind of place you describe in before-and-after terms. Before, you thought snorkelling in Oman was nice. After, you measure everywhere else against them.
When Is the Best Time to Snorkel the Daymaniyat Islands?
The honest answer: there is no bad season, only different ones.
- October to May — the calmest seas and the best visibility of the year. If you want textbook conditions, this is your window.
- May to October — turtle nesting season. Landing on the islands themselves is restricted to protect the nests, but snorkelling around them is still permitted — and the water is at its warmest.
- August to November — whale shark season. The sea can be a little livelier, but this is when the giants show up.
If you are visiting Muscat in the European winter — December to March — you happen to be arriving at peak conditions: warm water, light winds and superb visibility.
Do You Need a Permit to Visit?
Yes. The Daymaniyat Islands are a protected nature reserve, and every visitor needs a permit from Oman's Environment Authority. When you book with a licensed operator the permit is arranged for you — with Horizon Blue it is included in every tour price, along with the marine park rules briefing. You do not need to organise anything yourself.
How Much Does a Daymaniyat Snorkelling Trip Cost?
A shared half-day snorkelling tour with Horizon Blue starts from 30 OMR per adult and runs about five hours, with two departures daily from Al Mouj Marina — 8:30 AM and 2:00 PM. The price includes the licensed captain and crew, the reserve permit, all snorkelling equipment and refreshments on board.
If you want the boat to yourselves — your own pace, your own stops, your own music — a private half-day or full-day charter covers the same reefs with a completely flexible itinerary.
What Should You Bring?
- Swimwear (wear it under your clothes — it saves a changing-room scramble)
- A towel and a set of dry clothes for the ride home
- Reef-safe sunscreen, a hat and sunglasses — the sun out there is serious
- Motion-sickness tablets if you're prone, taken before departure
- A waterproof phone pouch or action camera if you have one
Masks, snorkels, fins and life jackets are provided on board, so you don't need to own or rent any equipment.
Can Non-Swimmers and Children Join?
Yes. Life jackets are provided and the crew picks calm, sheltered bays for entering the water, so confident floating is enough to enjoy the reef — plenty of our guests see their first turtle while holding onto a float line. Families with children join the shared trips all the time; just tell us the ages when you book and we'll make sure everyone is looked after.
