Wudalianchi is primarily about volcanoes, springs, lakes, and caves. We visited Yaoquan Mountain, the most spectacular of which was closed to the public. We also visited Beiyaoquan, Wenbo, and Erlongyan Spring. The lakes are located in the Wenbo Scenic Area. We visited Lianhua Lake and Yaoquan Lake in the Beiyaoquan Scenic Area. We didn't visit Sanchi and Longmen Stone Fortress, which seemed similar to the previously mentioned sub-scenic spots. The caves were also closed.
I was disappointed that Laohei Mountain was closed, but Wenbo, the most beautiful of the scenic areas, was indeed the most beautiful sub-scenic area in the Wudalianchi area. The Beiyaoquan Spring has a unique flavor, and Yaoquan Lake behind the Beiyaoquan Scenic Area is also beautiful in autumn. Although Yaoquan Mountain is a shorter volcano, a five-minute climb to the top, it's also beautiful in autumn, and the temples on the mountain are worth visiting. The Erlongyan Spring at the foot of Yaoquan Mountain tastes similar to regular mineral water, but it's said to improve eyesight and is quite refreshing.
Overall, it's well worth a visit and worth a visit when you're in Harbin.
