Last Saturday, Hai and his class went to Ba Be National Park. They arrived at 9:30 a.m. First, they went on a boat tour of Ba Be Lake. Hai thought the lake was very beautiful! He saw some fish in the water. Later, the pupils walked around the lake. They saw many birds and monkeys. They cooked their own food for lunch. In the afternoon, they went on a cave tour. The cave was dark and cool, with many bats. Hai thought the bats were very interesting. Then the pupils visited some waterfalls. They went for a bike ride before going home. It was a wonderful trip.
