THE REEF
Where We Go
Where Do We Go? The Daymaniyat Islands Nature Reserve
Daymaniyat Islands
The Daymaniyat Islands are a protected nature reserve off the coast of Muscat - home to some of the richest marine biodiversity in the Arabian Sea. The islands lie roughly 18 km offshore - a 45–50 minute crossing from Al Mouj Marina - with visibility of 15–25 metres between October and May. Crystal-clear waters, vibrant coral reefs, sea turtles, and exotic tropical fish await.

“Perfect morning at the Daymaniyat Islands with our two young children (4 and 6)!
Everything was perfect from start to finish. The team was very responsive on WhatsApp before the trip, and the welcome at Al Mouj Marina was excellent. Our captain was fantastic, and the whole crew took great care of us, especially the kids: life jackets, noodles and lots of patience in the water.
The snorkelling spots were beautiful and the snacks on board were very welcome. A great family experience that we highly recommend. Thank you, Horizon Blue!”

“Superb day out. Lovely people with no pressure sales. Big boat but small numbers. Caring captain who looked after us, didn't feel rushed. Lovely gopro videos shared fur free.
Good snacky brunch as well. Would go again”

“We had an amazing time at Daymaniyat Island, even swimming with turtles! We booked with Horizon Blue at the Muscat Marina, and Adnan was super nice and gave us tons of advice. The skipper was really professional and helpful. The food on board was great, including juice and water. We totally recommend doing this if you're visiting Oman, and definitely book with Horizon Blue at Al Mouj Marina!”
Quick answers about our tours, departure point and what to expect.
What tours does Horizon Blue run from Muscat?
Snorkelling tours and fishing charters out of Al Mouj Marina in Muscat. Three flavours: a shared half-day snorkelling trip to the Daymaniyat Islands (most popular, easiest to book onto), private snorkelling charters where the boat is yours for the day, and private fishing trips with a licensed captain who knows where the fish actually are.
Where do Daymaniyat Islands tours depart from?
Al Mouj Marina, Street 6, Muscat 113 - about 15 minutes from Muscat International Airport and 25 minutes from central Muscat. We send full directions when you book, but if you drop "Al Mouj Marina" into Google Maps you will land right at our gate.
How far is it to the Daymaniyat Islands?
Roughly 18 km offshore - a 45–50 minute boat ride from Al Mouj Marina, depending on the sea. Dolphins often turn up on the way, so the journey is part of the show.
What will we actually see down there?
Hawksbill and green sea turtles year-round, hundreds of species of tropical reef fish, vibrant hard and soft corals, stingrays, and moray eels - the full reef cast. From June to November, whale sharks pass through the Daymaniyat Islands waters. Nobody honest guarantees marine life, but turtle sightings on our snorkelling tours are very, very common.
When's the best time to come?
October to May is prime time - calmest seas, clearest water (visibility usually 15–25 metres), and the most comfortable weather. May to October is sea turtle nesting season, so the islands themselves are off-limits to land on, but the snorkelling around them stays excellent. If whale sharks are top of your list, aim for late August to early October, the peak of the June to November season.
What's included in the price?
All snorkelling gear (mask, snorkel, fins, life jacket), water, juice and light snacks, and a licensed captain and crew. The Daymaniyat Islands Nature Reserve permit is not part of the trip price: it is OMR 3 per adult and OMR 1 per child on the sharing tour (OMR 0.5–3 per person on private charters, depending on nationality), added to your booking and arranged by us.
What should I bring?
Swimwear, a towel, reef-safe sunscreen, sunglasses and a hat. Everything else is on board.
Is it suitable for children or weak swimmers?
Yes - life jackets in all sizes are provided and required for non-confident swimmers, and our snorkelling stops are chosen for calm, relatively shallow water. Children are welcome with a parent or guardian, and under-5s join the sharing tour free.
What happens if the weather turns?
If the coastguard closes the sea or conditions are unsafe, we cancel the trip ourselves - you can move your booking to another day or receive a full refund.
How do I book?
Online is fastest - head to horizonblueom.com/book and pick your trip. Or call +968 93232 837, or message us on Instagram @horizonblue.om. We reply quickly. If you are putting something custom together (private group, specific dates, hotel pickup), say so in the booking notes and we will sort it.
