Yes, as a tourist to Abu Dhabi, whether staying in the Abu Dhabi emirate, Dubai emirate or anywhere in the UAE, you will need a valid "Green Pass"on Al Hosn, or evidence of a recent PCR test in order to enter the Sheikh Zayed Grand Mosque in Abu Dhabi (in addition to meeting the Mosque's strict dress code requirements). The only exemption to this was introduced on 10 October 2022 for cruise ship passengers and crew. We can confirm this applies to those arriving in Port Zayed, Abu Dhabi. We are seeking clarity if cruise passengers arriving at Rashid Port in Dubai will have the same exemption if they take a shore excursion to Abu Dhabi emirate.
