Muscat And Daymaniyat Islands Oman
Boat dive a protected nine-island sanctuary, then eat shawarma on the corniche

Safety And Conservation
Muscat diving is generally straightforward, but it is still open-ocean boat diving with variable currents and visibility. Carry an SMB, follow local briefings, and treat the Daymaniyat reserve rules as strict. For diving medicine, Muscat has hyperbaric capability at The Royal Hospital.
Top Risks
- Primary risk: Dimaniyat landing and camping restrictions
- Secondary risk: Variable visibility and plankton blooms
- Emergency contact: Royal Oman Police Operations Center (9999)

Dive safety
On-water Practices That Matter Here
- Stay close to your buddy on reef edges and walls, especially when visibility drops.
- Carry and know how to deploy an SMB, and expect live boat pickups.
- If current is running, follow the guide's plan and avoid separating from the group.
- Manage heat on the boat with shade, hydration, and electrolytes.
Flight and Driving Planning
- Keep conservative profiles, track nitrogen loading with a computer, and follow standard no-fly guidance before flying.
- If you are doing long mountain day trips after diving, keep the timing conservative and discuss plans with your operator.
Muscat's primary reference for dive-related injuries is The Royal Hospital, which lists a National Hyperbaric Medicine Center and a 24/7 call center. If you suspect decompression illness, call emergency services immediately and follow DAN-style first aid: oxygen if available, keep the diver hydrated if conscious, and avoid exertion.
Carry dive accident insurance (DAN or equivalent) and store your policy number and emergency hotline in your phone before the trip.
Snorkel and freedive safety
Dimaniyat landing and camping restrictions
Entering or camping in the reserve is prohibited from May to October. Even outside that window, camping is only allowed on specified islands and under strict capacity limits. Do not assume you can step on shore.
Variable visibility and plankton blooms
Visibility can change fast between sites and seasons. If the water is green, slow down and stay tighter to your buddy and guide, especially on wall dives.
Currents around corners and channels
Some Daymaniyat sites run as drifts when current picks up. Carry an SMB and be ready for live pickups.
Heat stress on boats
From late spring through early autumn, heat and sun exposure are serious. Hydrate early, use shade, and bring electrolytes.
Wildlife and protected areas
Dimaniyat Islands Nature Reserve Rules (high Level)
- Paid permits are required to enter the reserve, with different categories for visiting, diving, and overnight stays.
- Entering or camping is prohibited from May to October. Outside this period, camping is only allowed on specified islands and under capacity limits.
- No-take behavior is enforced: collecting or destroying corals and marine life is prohibited.
- Turtle rules are strict: disturbing nesting turtles or their eggs is prohibited.
- Leave no trace: remove all trash, do not dump waste, and do not damage signs or facilities.
Treat wildlife as the priority. Keep distance, do not chase animals for photos, and follow your operator's approach protocols for turtles and whale sharks.
Do Not Do This
Avoid entering when dimaniyat landing and camping restrictions. Confirm local briefings before committing.
