Hello, I want to go to Anji to see the Bamboo Sea Forest. Is it easier to go from Shanghai or from Hangzhou? I want to learn more about visiting this place--I heard there may be a rollercoaster ride and a zipline ride and also a walk along a waterfall above the ground on a scaffold trail. Is this true? Also, I heard that people living at the forest may approach you and offer to let you stay in their homes for a cheap price. Is this true? Thank you!
