We love the Caribbean as much as the next person, but here are a few more options for you to consider:
Mozambique is known for its paradisal golden beaches that are largely undisturbed by loud, sunburnt tourists. Tofo is probably most well known as it is a relatively popular spot for swimming with whale sharks. Alternatively, Vilanculos is home to many well-protected coral reefs which have great visibility- perfect for diving. Plus, the Bazaruto Archipelago is just off of the city. Aside from surfing and sandy beaches, Bazaruto is famous for its wildlife- it’s home to many endangered species like the dugong, humpback whale, and leatherback turtle. Santa Carolina is a rock island and considered the paradise island of the archipelago. The one thing to keep in mind when on the idyllic coast of Mozambique is to be a savvy traveler: be careful with valuables, don’t walk alone at night (especially women), and so forth. December to April is the summer season there- so you definitely have time to plan your trip before the word gets out about this hidden gem.
This Indian state is one of the biggest party cities in the world, and the attraction only multiplies in the winter especially around Christmas and New Years. Of course, you can expect great food, amazing beaches, flea markets, water sports, and the like, but Goa is also home to amazing cultural heritage sites. Be sure not to miss Basilica of Bom Jesus (UNESCO World Heritage site), Tomb of St. Francis Xavier, Mangeshi Temple, Shantadurga Temple, and a variety of ancient ruins, to name a few. Boasting insanely beautiful beaches and architecture in addition to being one of the worlds best party destinations- Goa has a lot to offer and there is no better time to go than in the winter.
Bora Bora is the most popular island in French Polynesia thanks to it’s luxury status, where you can stay in overwater bungalows. This is mainly a honeymoon destination, though. Tahiti is another big island in French Polynesia but it is primarily the stopover to get to other islands, rather than being the destination itself. Another popular island is Moorea, which is similar to Bora Bora in that it is also a honeymoon destination, but it has a little more of a mix, with hiking and archaeological sites. Even more discreet is the Tuamotu Archipelago which is great for scuba diving and snorkeling, although there's not much to do on shore, except visit a black pearl farm, if that's your thing. There are so many islands to choose from, it’s worth spending time researching which you want to go to as some islands are better for water sports, some are better for luxury resorts, and some are better for sunbathing and other outdoor activities. The weather is pretty consistent all year round, but “summer” there is from November to April.
Note: people often compare The Maldives to Bora Bora because both have the overwater bungalows, however, The Maldives receive over a million visitors per year while French Polynesia receives just a fraction. There is little privacy in The Maldives and many accounts of people disrespecting the marine life. If you want a secluded and romantic getaway, French Polynesia is for you, but if you want a busier and more budget friendly place look to The Maldives.
