Time for an adventure?
Are you a bit bored with your ninetofive routine? Have a look at our exciting range of holidays and decide what type of adventure you'd like.
Activity holidays
Our activity holidays are for everyone, people who love danger or who just like sports. We have a huge variety of water, snow or desert holidays. We'll take you SCUBA diving in the Red Sea or kayaking and white water rafting in Canada. If you prefer snow, you can try skiing or snowboarding in the Alps or even igloobuilding. For those who like warmer weather, we also have sandboarding (the desert version of skateboarding) or camel safaris (游猎).
Polar expeditions (探险)
Take an expedition to Antarctica or the northern Arctic; explore a land of white natural beauty and wonderful wildlife. Our experts will explain everything about the two poles as you watch the penguins in Antarctica or whales and polar bears in the Arctic. There's no greater adventure than travelling to the ends of the earth, a onceinalifetime experience.
Cultural journeys
Our cultural journeys will help you discover ancient civilizations：India, Thailand, Egypt and many more. Visit temples, palaces and ancient ruins—just remember to bring your camera! Get to know local ways of life by exploring markets, trying exotic foods and meeting local people.
Wildlife holidays
We organize smallgroup tours to get closer to nature in Africa, Asia or South America. Go on safari in Africa and watch lions and giraffes. Meet the famous turtles off the Galapagos Islands.
