The Maldives is a manageable destination for celiac travelers, but success depends almost entirely on advance communication with your resort rather than on any broader national infrastructure — there's no national celiac association, and no meaningful grocery or restaurant access outside the resort you're staying at. The upside is that resort staff are well-practiced at accommodating international dietary requests: at Anantara Veli, all four on-site restaurants worked with me once I gave advance notice. Traditional Dhivehi cuisine's reliance on rice, fish, and coconut also means naturally GF dishes are easy to find once you're eating local.
Country scores are not city averages. This 5/10 reflects the Maldives' overall infrastructure — no national celiac association, no supermarket backup, no dining outside the resort bubble — while South Malé Atoll itself scored much higher at 8/10 because Anantara Veli's kitchens handled my requests carefully once given advance notice. Expect your own experience to hinge on which resort you pick and how much notice you give them, more than on any national standard.
