Certification & difficulty

Advanced Open Water - advanced conditions (currents/depth); dive within your training.

Snorkelling

Not a snorkel site - Not confirmed site-specific; Daymaniyat sites generally offer shallow reef-top snorkeling, and Aquarium's shallow 7m start could suit snorkeling, but no direct source confirms snorkeling at this exact site

Safety notes

Thermoclines with 7-8C temperature drops; occasional old fishing-net debris; site lies partly outside reserve protection so boat traffic/current exposure can be higher than inner reserve sites

Permits & fees

Diamaniyat/Dimaniyat Islands Nature Reserve entry permit required via Oman's Environment Authority (apply and pay online, ea.gov.om); 1-day fee approx OMR 3 for foreign adults, OMR 1 for Omani nationals (children lower); multi-day/annual passes available; island landing closed May-October for turtle nesting, though boat-based diving trips around the islands continue year-round

Permits and operators change - confirm before booking.
