About 500 participants of the Beijing Olympic Youth Camp have climbed the Great Wall. Campers say the trip has helped them get close to Chinese history and they're having a great time in Beijing.

A cultural heritage like the Great Wall is an important part of these young people's camp experience.

Many say what they heard before coming to China didn't really prepare them for the reality of the Great Wall.

Johanna Bergdahl from Sweden said "It's very hard to walk all the way up. It's cool, as cool as watching sports, China has such great history." Joanna also says she likes the camp's arrangement of cultural activities.

And many other things have impressed these young people in the past week.

Emnet Negussie Aberra from Ethiopia said "The people, they are friendly, really nice."

Mduduzi Xaba from Swaziland said "The city is so great."

Planting trees may be a good way to leave a legacy of friendship.

Oyerinde Kemi from Nigeria has caught the spirit with her new friend from the Seychelles.

Oyerinde Kemi from Nigeria said "As we planting the tree, is like planting for the future. We contribute to the community."

A boy from Kenya is hanging a wish card on the tree he planted.

Stephen Okutu Wokila from Kenya said "I hope it will help keep Beijing green and clean."

These two girls are trying to mark their tree with the names of their countries.

Nancy Lama from Nepal said "Maybe in the future, we will come back to China, when we come to this place, we can remember all the beautiful memories in youth camp."

The youth camp ends on Sunday. Most campers say the camp has given them a good chance to learn not only about the Olympics, but also about China.
