Live Your Best Lives
Chuiyun Tongtian River is an underground karst river. Due to factors such as crustal movement and volcanic eruptions hundreds of millions of years ago, it formed a typical karst landform.
There is a kilometer-long underground river, which is just wide enough for boats to sail, and it also makes it a sightseeing way to drift in the cave.
Not far from Yaolin Wonderland, although they are all caves, it is more interesting to drift in the cave on a boat on the Chuiyun Tongtian River, which is a completely different sensory experience.
Attraction Location: "Tonglu County (桐庐县), Hangzhou City (杭州市), Zhejiang Province (浙江省)"
History: Chuiyun Tongtianhe is a famous karst cave scenic area in Tonglu, known as one of the largest and most magnificent underground river caves in East China. Its name “Tongtianhe” literally means “the river that connects to the sky,” reflecting the mystical feeling of its grand cave system and underground river. The site has been developed as a tourist attraction since the late 20th century but retains much of its natural geology.
Architecture: The cave features naturally formed stalactites, stalagmites, stone curtains, and an underground river with boat rides. The lighting design inside highlights the unique formations, creating a colorful and mysterious atmosphere. Outside, traditional pavilions and stone paths integrate the scenic site with the surrounding mountains and forests.
Cultural Value: The site is a key attraction in Tonglu, often associated with Chinese landscape poetry. Tonglu itself has long been praised as “a paradise on earth” by poets since the Tang dynasty. Chuiyun Tongtianhe embodies this poetic spirit by blending natural wonder with cultural heritage.
Other Information: The cave system includes underground waterfalls, echo chambers, and boat tours, making it both a geological spectacle and an adventure spot for families and nature lovers.

Tickets are 108, and children under 1.2 meters are free. Chuiyun Tongtian River is similar to Yaolin Wonderland, but it is not as popular and has relatively fewer people. 10 people share a small boat, and the staff paddled into the cave. The cave was very cool, 18 degrees Celsius all year round, and the water was even colder. Fortunately, we prepared sun protection clothes for the children in advance, which were both warm and waterproof in the cave. The stalactites were all kinds of strange, and the children had rich imaginations and could describe them in various ways. They were very excited. The elderly were also very happy and kept saying that they had seen the wonders of nature. It was much more beautiful than Zhanggong Cave in Yixing.
The underground cave, known as one of China's most unique attractions, must be a popular attraction. We waited in line for over an hour before boarding the boat. A celestial aura lingered at the cave entrance, allowing us to enter and experience the wonders of nature. After disembarking from the boat, a long, seemingly endless staircase awaited us. There was also a glass rafting ride on the mountain. The water slide didn't go straight down, but twisted and turned several times, so it wasn't as scary as we'd imagined. It was quite fun.
The scenic area is open from 8:00 AM to 4:30 PM. After purchasing a 108 RMB Chuiyun Tongtian River tour ticket, the ticket inspector will hand you a guide with your boat number. A staff member at the dock will call out your number, and you'll board the boat based on the number on your ticket to begin your Chuiyun Tongtian River tour, the first attraction of the river: Underground River Boating.
Once aboard, the boatman, who also serves as a guide, will lead the group into the underground river. In addition to the boatman's large oar, each boat also has two smaller oars for rowing and taking photos. (Giving a heart!) As the boat sailed forward for a while, a haze began to linger, creating a sense of immersion in a fairyland. Slowly, we entered the underground river. Warm in winter and cool in summer, the water is clear and maintains a constant temperature of 18°C. The vibrant colors of the cave gradually emerged before our eyes.
While taking photos, be mindful of your surroundings. Tall people, especially, keep your head down! The refreshing coolness contrasts with the scorching temperatures outside, making it a truly worthy summer retreat. Inside the cave, you'll find countless bizarre and mysterious sights. As the boatman steers, he explains them one by one: Dinghai Shenzhen, Dong Shi Xiou Pin, Hou Lianting Zheng, and Yixiantian Tian. Only by unleashing your imagination can you discover the allure of the cave's beautiful stalactites.
It is more cost-effective to buy tickets online in advance, but please note that tickets purchased on the same day can only be used four hours later. We were half an hour late and could not use them, so we had to wait.
There are two options: a boat tour of the caves and a cave exploration tour. We only chose the boat tour, as walking is generally not recommended with children. The boat hostess provided explanations while rowing, so there was no need to worry about missing anything. There's a drop in the cave, and the boat ride requires a water elevator, which feels like a time tunnel.
You need to climb high steps to get out of the cave. There is a water slide outside the cave entrance. It costs 68 per person, which seems expensive. The children think it is fun.
Drifting through the caves on the Chuiyun Tongtian River in a boat is even more interesting and offers a completely different sensory experience. The riverbed is well-developed with karst landforms, abundant groundwater, and fresh, ever-changing air, making it a truly captivating experience.
The regular price is 108, and the online price is 98 (including a boat ride). The cave is a great way to beat the summer heat. The cave is colorful and very cool. Most caves are accessed on foot, but this one is unique in that you need to row a boat to visit. You need to duck your head to get through low rocks. The water here is very green, like a flowing lake, and the scenery is beautiful. Weekends are busier, so if conditions permit, come on weekdays or early.
Taking photos at the entrance was such a rip-off. When I entered, she said it was free to take photos, and I had to come out to get them. When I came out to get them, she said it was 20 yuan, and gave me a very small photo. I didn't want the photo, so she took a large one. I asked for 20 yuan for the photo, but when I took it, she said it was free. What a rip-off.
The most worthless scenic spot, the fees are surprisingly high. A short 30-minute boat tour of the caves, and then a dark, damp and low cave, costs about 300 yuan, which is really disgusting.
What impressed me most about Chuiyun Tongtian River was the underground caves.
I went here for a trip with my girlfriend the day before yesterday. This place is very nice and the air is very fresh. I was not in a good mood that day, but I felt much better after the trip.
The environment is elegant and the scenery is pleasant. It is very suitable for relaxation.
The main thing is that there are many activities to play, one after another, which I think is a good way to cool off and escape the summer heat.
The boat trip to the cave is suitable for lazy people like me. I am generally satisfied with it. I recommend using the night scene mode to take pictures of the scenery inside the cave, which will definitely make you feel that the trip is worthwhile.
It’s my first time here, and I really didn’t choose the wrong place. The environment and air are really great. Next time I will bring my whole family here to play.

This place is very unique. There is a small boat floating in the river, and the scenery along the way is very unique. The wind in the cave is very strong, and it is a bit cold if you stay there for a long time. The stalactites are also very beautiful. It is worth a visit.
The scenery is particularly beautiful. It is very enjoyable to take a boat on the water. The scenery in the cave is also very beautiful. It is a good place to go out for fun.

I have traveled to many places, but the Tongtian River Scenic Area really left a deep impression on me. The gate of the Tongtian River is majestic and magnificent, and the stalactites are strange and colorful. I recommend everyone to visit it.

The cave is beautiful and spectacular. It’s fun to play there and it’s pleasing to the eyes. I will bring my parents here to play in a few days!
The roar of the water and the hum of the motors offer a unique sense of thrill and excitement. Family photos are available, but there's a fee. Visitors can join Chuiyun Tongtian River's pioneering underground river adventure tours. Under the guidance of dedicated adventure guides, visitors will change into their own gear and bring their own lighting equipment. Led by a dedicated guide, they'll wade through the river, climb cliffs, and explore canyons, offering endless fun.
Wow, what a beautiful scenery, the flowers, plants and trees on both sides of the river, the rows of big trees on the mountain, and the blue sky, I don’t want to leave here.
This place satisfies all my fantasies about the Kashgar landscape. The internet-famous fountains and the Grand Canyon are indeed well-deserved.
It is so beautiful. The underground river terrain is wide and unique. I love this sacred place.
It is so magical, the wonders of nature are amazing. The lights in the cave are so colorful and beautiful that people will never want to leave.
It is really fun to come here. The fountain is also unique. It was not until I went to the cave that I realized that there are such places in the world. It is really eye-opening and it is worth the trip.
A beautiful place has its own beautiful scenery, with clear lakes, shady trees, singing birds and fragrant flowers. Overall, it is a place worth visiting.
I saw rows of big willow trees on the high mountain with their branches hanging down. There were also many wild flowers on both sides, blooming one after another. Butterflies came and the flowers bloomed beautifully.
In the warm spring, the earth is full of vitality after being blown by the spring breeze and moistened by the spring rain. The grass has changed into a tender green spring dress, dancing gracefully to the singing of the wind. This is a beautiful place! It deserves praise.
Walking in this beautiful scenic area, you can see willows and flowers on both sides, which is very dazzling. The air is fresh in this season. I will bring my family here to play next time.
Entering the cave requires a boat operated by staff, equipped with two oars for the pleasure of rowing. As the boat reaches the cave's entrance, a chilling chill hits you, like a monster gaping open its bloody maw. As you enter, you're suddenly struck by the feeling of "sudden enlightenment" described by Tao Yuanming: an unknown and fantastical world, a joyous and unique adventure, awaits. Only once inside the cave can you truly experience the idiom: a world beyond imagination.
Here you can find the magical Tongtian River and the colorful caves, which are very beautiful. The caves are cool and refreshing, and I love it!
Walking in this beautiful scenic area, you can see willows and flowers on both sides, which is very dazzling. The air is fresh in this season. I will bring my family here to play next time.
The most novel thing is the cave behind the underground river. The scenery in the cave is naturally formed, and the stalactites under the illumination of lights are particularly unforgettable and unforgettable.
The scenery is beautiful, the air is particularly good in this season, and there is a sense of ease and joy. The flowers are red and the willows are green, it is really beautiful.
The waves were rippling, and it was quite relaxing to sail through the mountains. The boat ride took about a quarter of an hour. There were some bumps in the middle, which wet my shoes, but in return I had a lot of laughter.
There are Chinese-style buildings, shady trees, and Jiangnan garden-like attractions. The attractions are mainly Tongtian River and underground caves. The boating location is in the Tongtian River scenic area. Generally, the caves are visited on foot, but this one is special. You need to row a boat to visit it. You need to lower your head to pass through the low rocks.
There are two water surface systems in the cave, with a drop of several meters. You can take a boat to go up. The scenery is beautiful. Children like it very much. It is worth a visit.
It's very beautiful. Children especially like this place. It is colorful and very helpful for children to develop their imagination. They were also very curious about the spring on the way back. This trip was very successful.
The ancient underground river boat ride is very interesting. The cave is the Kanas terrain. There are many strange stalactites in different shapes. They are particularly attractive when illuminated by lights.
The air is fresh, the flying boat is very exciting, the underground river cave is also very good, and there is a cable car to ride down the mountain. Children especially like it. Give it a thumbs up
Waves, rocks and golden beach.
The Chuiyun Tongtian Lake, an underground river, and a grand underground canyon are all part of the tour. The first half of the tour involves a boat trip into the underground river. The water is very shallow, requiring you to duck your head in many places to navigate. It's a truly magical experience, reminiscent of the waterways in the "Cadaver Cave" from the novel "Grave Robbers' Chronicles." You'll also get a glimpse of the bat roosting on the cave ceiling, which is truly spectacular. The landscaping in the underground river is also beautiful, and there's an opportunity to disembark and explore the area midway. The second half of the tour involves exploring the underground canyon, requiring helmets (which proved very useful, as I'd hit my head several times). Compared to the Yaolin Wonderland, the Chuiyun Tongtian River cave is narrower, but still offers its own unique charm. Upon exiting the cave, we were met with a spectacular misty spectacle. This is likely due to the extreme temperature difference between inside and outside the cave, causing the hot air inside to quickly condense into water vapor as it exits the narrow opening. It's truly a magical experience. Overall, the tour was a pleasant one, with many new discoveries.
