Hallaniyat Islands Oman
Expedition diving and Arabian Sea megafauna off Dhofar's wild island frontier
Updated Feb 13, 2026 • 20 sources
Safety And Conservation
Hallaniyat Islands are remote and sea conditions can change quickly. Plan conservatively, use experienced operators, and treat wildlife encounters as a privilege. The islands are within a newly established marine buffer zone reserve, so access rules and enforcement are expected to tighten over time.
Top Risks
- Primary risk: Khareef monsoon sea state
- Secondary risk: Strong currents and blue-water ascents
- Emergency contact: Royal Oman Police Operations Center (9999)
- Safety overview: Hallaniyat Islands are remote and sea conditions can change quickly.
Dive safety
Operational Reality
- This is boat diving in open-ocean conditions, not a sheltered shore-diving destination.
- Briefings should include currents, drift procedures, pickup signals, and lost-diver protocol.
Core Safety Habits
- Carry an SMB and deploy it on every ascent.
- Use a conservative gas plan and avoid pushing decompression obligations in a remote area.
- Maintain buddy contact in current and surge.
- Consider nitrox for margin on repetitive dive days (when available and trained).
Emergency Response
- For urgent emergencies in Oman, call 9999 (ambulance, fire, police).
- In Dhofar, hospital care is centered in Salalah.
Diving Injuries and Chambers
- Hyperbaric care in Oman is available at the National Hyperbaric Medicine Center at the Royal Hospital in Muscat.
- Because Hallaniyat is far from major facilities, evacuation time can be significant. Diving insurance that covers chamber treatment and medevac is strongly recommended.
Snorkel and freedive safety
Khareef monsoon sea state
June to September can bring rough seas and low visibility that limit crossings and offshore diving in southern Oman. Have a mainland Plan B and keep schedules flexible.
Strong currents and blue-water ascents
Currents can run around points and channels. Agree on drift procedures, deploy SMBs early, and keep ascents controlled and conservative.
Remoteness and delayed medical access
Evacuation from the islands can be slow. Carry dive insurance that covers chamber treatment and medevac, and confirm the operator's emergency action plan.
Fishing gear and lines
You are in active fishing waters. Carry a cutting tool and stay alert around lines, nets, and floating debris, especially near bays and anchorages.
Wildlife and protected areas
Reserve and Rules
- The Hallaniyat Islands Marine Buffer Zone reserve was established by Royal Decree 96/2025. The Environment Authority is mandated to define entry rules, fees, visiting times, permitted and banned activities, and penalties.
- Expect tighter controls over time, including permits for entry, camping, research, and potentially filming.
Wildlife Etiquette (minimum Standards)
- Whales and dolphins: never chase, cut off, or crowd. Reduce speed early and keep encounters passive.
- Mantas: no touching, no blocking cleaning stations, and avoid repeated close passes.
- Turtles and birds: keep distance, avoid flash and bright lights at night on beaches, and never approach nests.
Leave-no-trace Behavior
- Do not collect wildlife, shells, stones, or artifacts.
- Do not leave fishing line, plastic, or food waste.
- Follow any designated tracks and landing restrictions when going ashore.
Do Not Do This
Avoid entering when khareef monsoon sea state. Confirm local briefings before committing.
