While the Maldives is a very relaxed country, it is also a Muslim country. When on the local islands, you should respect certain local customs. For instance:

• You should not wear clothes in public that are too revealing (like bikinis). Most local islands will have designated bikini beaches if you intend to wear revealing swimwear. You may still use the other public beaches, but you must wear swimwear that covers your body if you do. When it comes to public areas like towns, most locals are lenient towards tourists. However, you should not take it too far and wear clothes that are very revealing (i.e. short-skirts, clothes that reveal your bum or breasts, etc.).
• There is no alcohol on local islands. You will not find any alcoholic drinks on local islands, only on private resort islands. Do not try to bring your own alcohol either, as it will likely be taken away, and you may even be prosecuted.
• There is no pork. Muslim countries do not have pork due to Islamic rulings. You may find some on private resorts, but not on local island. Much like the alcohol, do not try to bring any pork into the country.
• Refrain from public indecency. Things like passionate kissing/making out/groping/sexual acts in public are not allowed. Of course, simple things such as holding hands and hugging are fine. Just be cautious when things get intimate.
• It is a Muslim belief that Men and Women should not touch each other, unless it is family/spouse. So dont be offended if someone from the opposite gender avoids touching you. And try to respect this belief when it comes to shaking hands or hugging. However, not all Maldivians are so strict.
