This Time Tunnel is a combined ticket with the Qiandao Lake Botanical Garden ticket, and parking is convenient. Buying tickets separately would be too expensive. Inside, there are three long tunnels, each showcasing a different theme using light and shadow. The tour takes about half an hour. Because of the hot weather, we went to the Time Tunnel in the morning and visited the Qiandao Lake Botanical Garden in the evening. Inside the botanical garden, you can feed small animals, mainly alpacas, deer, and rabbits. Families with young children can bring some fruits and vegetables. The little red house with the beautiful light and shadow is the marriage registration office. From the parking area to the Qiandao Lake Botanical Garden, it's about a 1-kilometer walk. If you don't want to walk, you can buy a ticket for an electric vehicle. The tour of the Qiandao Lake Botanical Garden takes about two hours.
