Daymaniyat Islands: Snorkeling Guide

Everything you need to know before you visit Oman's first marine reserve: turtles, whale sharks, permits, the best season, and how to choose a trip.

The Daymaniyat Islands are the jewel of Oman's coast: nine uninhabited islands and the country's first protected marine reserve, just 40 minutes by boat from Muscat. This guide covers what they are, what you'll see, the permits, the best time to go, and how to make the most of a visit.

What are the Daymaniyat Islands?

The Daymaniyat Islands (also spelled Dimaniyat, Ad Dimaniyat, Damaniyat or Daymaniat, all the same place) sit about 18 km off the coast between Muscat and Barka. Designated a nature reserve in 1996, the islands and their reefs are protected by Oman's Environment Authority. They're uninhabited, which is exactly what keeps the water and reefs so pristine. It's Oman's most popular marine reserve.

What you'll see underwater

  • Sea turtles: resident green and hawksbill turtles, the headline attraction
  • Rays: gliding eagle rays and stingrays over the sandy shallows
  • Coral gardens: hard and soft corals in remarkably good health
  • Schooling fish: parrotfish, fusiliers and snappers
  • Whale sharks: seasonal summer visitors; see our whale shark guide

Permits: what you need to know

Because it's a protected reserve, every visitor needs an Environment Authority permit, and the islands have daily visitor limits. You don't arrange this yourself. A licensed operator does it for you. On our Shared Half-Day Snorkeling Tour the permit is included; on private charters it's arranged per guest.

Best time to visit

Nov-Apr (high season)Cooler air, calm seas, visibility 20-25 mBest all-round snorkeling; overnight camping
May-Oct (warm season)Warm water, whale shark season; landings restricted for nesting, snorkeling boat-basedWhale sharks, quieter reefs

How to get there

There's no public ferry. You reach the islands on a licensed boat from a Muscat marina. We depart Al Mouj Marina, a roughly 40-minute crossing on a custom-built 36-foot boat with shade and a toilet.

How to choose a trip

  • Join a small group, or go private for the whole boat and your own pace
  • Check the boat and gear: newer is more comfortable and safer for the crossing
  • Look for safety and licensing: life jackets for all, a guide in the water, permits arranged, insurance
  • Choose an operator who protects the reserve: small groups, buoy mooring, no single-use plastic
