Where We Go
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.
“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!”
“I had an excellent experience with Horizon Blue. The entire trip was professionally managed from start to finish, with a strong focus on safety, comfort, and customer satisfaction. The crew was knowledgeable, friendly, and attentive, making the journey both relaxing and enjoyable. Anyone looking to go to Daymaniyat, book with horizon blue !”

The Journal
Travel TipsOn 1 November the Daymaniyat Islands open their beaches to visitors again. Here is what changes for travellers, tour agents and DMCs: beach landings, a full-day trip with an Omani BBQ, short climbs to the island viewpoints and an itinerary built around your group.
AdventuresFrom the turtle reel that opened June to the reef roll-call we posted as September closed: summer 2026 at the Daymaniyat Islands, told reel by reel through our own Instagram feed. Every picture is from our own posts.
Travel TipsSeptember is the month the guidebooks skip and the crews quietly rate: the heart of whale shark season, water at 29–31°C, sooty falcon chicks fledging on the cliffs, and some of the emptiest boats of the year. Here's what September at the Daymaniyats is actually like — including the one trade-off nobody explains properly.

Plan Your Trip
Quick answers about our tours, departure point and what to expect.
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.
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.
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.
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.
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.
All snorkelling gear (mask, snorkel, fins, life jacket), water, juice and light snacks, and a licensed captain and crew. On the sharing tour the Daymaniyat Islands Nature Reserve permit is included in the price; on private charters permits are charged per person and confirmed at booking.
Swimwear, a towel, reef-safe sunscreen, sunglasses and a hat. Everything else is on board.
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.
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.
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.
