If you're into outdoor adventure vacations, and want something slightly off your radar, here are a few thoughts:

Phu Quoc Island in Vietnam - Whether just enjoying the glorious beaches or taking advantage of the great scuba diving and snorkeling, Phu Quoc will surely take your breath away. You'll find waterfalls and rock pools, jungle walks and motorbike tours. And, it's not many places you can go on a night tour of squid fishing! Twenty percent of the island is national park, but there are still great accommodations to choose from, such as Saigon Phu Quoc Resort and Spa, which is a four-star hotel or the Mango Bay Resort at Ong Lang Beach with earthen bungalows. The prices of which range from inexpensive to moderately expensive. The island has a good all-year climate, but the best times of year are from November to May (west coast) or May to September (east coast). You may want to avoid going there during the October rainy season.

Jericoacoara in Brazil - Known as "Jeri," Jericoacoara can be found at the northern part of the Brazilian state of Ceará. A remote island, Jericoacoara can't be gotten to easily, and that, for some people, is half of the adventure. It's a 4-hour trip from the airport (6 hours by bus), which must be done with 4-wheel-drive vehicles, as many of the roads are rugged, dirt roads, with the final stretch along the sandy beach itself. You can either hire a transfer service, or rent a vehicle yourself. But, for those willing to take that adventure, you will be rewarded with stretches of beaches which seem to stretch into infinity, the best windsurfing in Brazil, and views you probably can't even imagine. Because of its location, visitors to Jeri are able to see the sun rise and set into the water. The best time to visit is between July and December. Avoid the rainy season of February to May.

The Kangaroo Island in Australia - It’s not very many places where you can walk through immense colonies of fairy penguins and sea lions, as well as spot kangaroos, koalas, wallabies, bats, and goannas (a type of big lizard). But, you can on Kangaroo Island, Australia's third-largest island, located southwest of Adelaide. With soaring cliffs, towering sand dunes, dense forest, and spectacular white beaches, it's no wonder Kangaroo Island is a popular adventure destination. While there do give sand boarding a shot at Little Sahara, where you can climb immense sand dunes and ride down on a sand board. ATV tours of the bushland trails are also popular, as well as guided caving tours. Go June through November for great wildlife.
