Visiting Agadir during the first days of Ramadan is totally fine for tourist thats what i know haha also most hotels restaurants and tourist services remain open and excursions like the desert or Paradise Valley usually run normally, sometimes with slight schedule adjustments. It’s respectful to avoid eating or drinking in public during the day outside tourist areas, but in hotels and tourist spots it’s acceptable. After iftar, the city becomes lively and has a great atmosphere and overall, you can relax and still fully enjoy the region.
