     Is there something that you've always wanted to try but just never had the time? Well, make plans to

try it now since you are on summer vacation. Not all vacations call for taking a tour bus to take photos

of famous landmarks. Some vacations allow you plenty of opportunities to learn.

     The most difficult aspect of a learning vacation may be choosing one because the possibilities are

endless. If you enjoy cooking, various companies can take you to Italy, France, Spain, Mexico or even

Peru. Once there, you can learn to prepare the local cuisine(烹饪). Trips are often planned to fit in with

local food festivals or special events.

     The term “learning vacation” often brings language to mind.The best way to learn a language is in an

environment where it's spoken. Study Spanish, French or English. Or attempt a more unusual language

like Polish, Estonian or Thai. You'll be able to learn about the country and absorb the culture at the

same time.

     If you are fond of sports, you can polish your skills or learn new ones. Golf and tennis schools

welcome players of all levels. If you want a bigger thrill, you can learn to surf, go climbing or race cars.

     It's even possible to learn the art and techniques of bull fighting while on vacation!

     You can also discover our inner artist. Many places offer painting classes in different mediums. The

scenic locations of the schools offer plenty of subjects that provide inspiration for practice.

     If you prefer capturing the world on film, take a photography vacation. Travel with a small group to

photograph beautiful animals or scenery. You can also practise your technique on people or at historical

sights.

     Once you decide on a vacation, choose a company carefully. Request names of recent customers

you can contact, and then ask them for an evaluation. The more you know before you go, the better

prepared you'll be. Then go out and learn something!
