     Welcome to Ontario Parks, a new body set up to manage Ontario's most treasured special places, the parks

in our area.

     We are entering a very exciting year for Ontario Parks. Last season we asked some 15,000 visitors in 45

parks how we could improve our programs and services. We also looked at the thousands of comment cards

we received. As a result, new comfort stations have been added, the number of campsites has been increased,

and we've made other facility (设施) improvements. In addition, we'll be providing more educational programs.

This year, for example, more than 40 parks will offer special day and evening activities to excite your curiosity

about nature and history.

     Through the Internet, you'll be happy to know that you can now explore all 270 parks on line. Let your

family plan your park vacation, study a map of canoe routes, listen to the call of a loon or find up-to-date

information about programs, services and facilities.

     So come and discover what Ontario Parks has to offer. Our parks are places to go with families and friends,

for relaxation and fun, or simply to get away from it all. They are places where we can enrich our souls and

"recharge our internal (内部的) batteries". They provide chances to explore nature, see wildlife, swim, canoe,

camp, hike, picnic, ride a bike… You'll enjoy some of the best outdoor experiences available anywhere in the

world.

     We urge you to make 2006 the year that you come out and have an Ontario Parks experience!
