　　For those traveling on a tight budget，hostels are the best accommodation option. Informal places usually with a friendly youthful vibe，they offer dormitory beds for rent. Bathrooms are usually down the hall.

　　Remember to check reviews by previous guests online before you book your hostel.

　　Couch Surfing

　　An unusual but interesting option，couch surfing is a growing trend among young internationals. The idea is that you become a member of the online couch­surfing community (www. couchsurfing. com) and then when you travel，look up other members in that country and ask to stay on their couch(沙发). Most hosts will suggest sightseeing trips and take you out in the evening，making it a great way to see things that aren't in your guidebook. And remember，it may be free but don't forget to offer to buy your host a drink or dinner.

　　Sleeping under the stars! For budget travelers staying at camping grounds is the cheapest way to travel. The drawback is that you have to carry a tent with you. Camping grounds can be found across Europe，America and Australia. However，if you intend on camping in busy cities，check first where the nearest campsite is. More often than not，they are on the outskirts，which can mean lengthy bus rides into town when you want to eat or see the sights.
