"The summer heat is forgotten, but the winter travel is like spring. Although the origin is the same, innocence only hangs in the clouds." It is about a karst underground river located in Tonglu, Zhejiang, called the Tongtian River.

The heat is here and I want to find a beautiful, fun place to spend a day in the summer. Tonglu around Hangzhou has become a new choice.

We made a few friends and drove ourselves from Hangzhou to the scenic spot. It took about more than 2 hours, and driving was not tiring.

In a place with beautiful mountains and clear waters, there is always something to play with.

Due to factors such as crustal changes and volcanic eruptions hundreds of millions of years ago, a typical karst karst landform has been formed here, with bizarre shapes and colors, like the scene in "Tomb Robbing Notes" written by the Third Uncle of the Nanpai. This is the Chuiyun Tongtian River, known as the first underground river.

Get on a wooden boat and paddle on the green and clear lake. The black swan is swimming comfortably and joking.

Entering the underground river cave door, a coolness comes to your face. The constant temperature here is 18° C all year round, the water quality is clear, and the heat of the scorching heat suddenly disappears.

The karst landform in the river here is well developed, with abundant underground water sources, sweet water quality, fresh air, gurgling water all year round, and the river is winding and deep, forming pools, moors, or waterfalls, rapids and shoals. The changes are endless, making people linger.

Due to recent days of rainfall, the water level of underground rivers is high, and stalactite heads in many places are already within reach. You have to bow your head to enter, otherwise you can easily hit your head.

It is full of living stalactites, so some places still drip. It is said that these stalactites take about 100 years to grow by 1 cm. Our tour guide is an old employee who explains very carefully and controls the rhythm very well.

If you look carefully, these stalactites have really grown into various shapes, such as sharks, penguins, jellyfish, mushrooms, bergamot... lifelike.

The Tongtian River is a one-way line. Guests will not return after landing, but ships will return to their starting point. The entire river has a winding path and varies in width. The narrowest part is probably only one boat that can pass through, which is especially suitable for friends who want to explore.

The overall lighting in the river is particularly good, which is said to be the result of many renovations.

When you reach the middle area, there is a "Dongtian Buddhist Kingdom" where you can land. It is the only place you can visit ashore for a boat tour of the Chuiyun Tongtian River Scenic Area. There are three major natural landscapes, known as the "Three Wonders of Hanging Clouds", which is the biggest highlight of the underground Hanoi.

It is a unique "map of China". It is layered on top like terraces. It belongs to a type of karst landform and is formed by the erosion and deposition of calcium carbonate in limestone from top to bottom.

The second unique "Guanyin Stone Statue" is in a yurt formed by sheet water flow. Three unique "natural stone dragons", you can see the dragon head, dragon body and dragon tail here, which is very vivid.

People can walk through the stone pillars to a relatively empty area, and then the boatman will wait for you to board the boat at the dock here.

Back on the boat, we welcomed the most spectacular stalactite in the entire Tongtian River, heading straight into the sky.

There are also colorful jellyfish areas and realistic dynamic shark areas.

The last climax is at the end of the day, passing through a color-lit space-time tunnel, where the ship can be directly taken to a large disembarkation area and end the visit of the entire underground river.

The whole trip experience was great! The most important thing is that it was really cool inside. I was about to leave this comfortable and charming natural central air conditioner. I was really reluctant to part with it. As soon as I returned to the road, the 35° high temperature was welcoming us again, and my glasses and cameras were starting to fog. This was really my trip with the biggest contrast in temperature differences in summer.

At the end of the river, there is a forested area of nearly 30 square kilometers. Looking into the distance, you can see a silver necklace hanging in the air. This is the thrilling "Lingyun Bridge".

From the underground river to the Lingyun Overpass, you have to go through a long staircase, and you need to conserve your physical strength. When you see the sky, you will see the "Angel Corridor". Passing through the white arch full of flowers "Angel Corridor", it is the classic "Angel Wings" shooting point.

Behind the Angel Wings are transparent glass and green forest farms. From a distance, they look like a little fairy spreading her wings and flying in the mountains. So when you come here to take photos, you can dress up a little more and look better on the camera ~

After walking through several shooting spots, we arrived at the thrilling glass plank road "Lingkong Bridge".

This 300-meter-long glass "Lingyun Overpass" has an abyss hundreds of meters under its feet. It is suspended by a tie rod. The moment you step on it, it will make people scream

Put on shoe covers and try forward slowly. You will find that the trestle will shake after a few steps. Feeling the uncertainty at high altitude can really make people feel scary.

The moment I try it for the first time, I feel a little uncomfortable. My secret is to try to look forward and not look down, and it will be much better.

Those with weaker psychological construction may retreat, be a little bolder, and try to take a few steps. If you have friends who are afraid of heights, don't try it.

The glass here is very transparent, because everyone has to wear shoe covers to go up, which are very well protected. With a thin layer, you can see the world under your feet at a glance, and the abyss reaches the foot of the mountain.

Viewed from a distance, this silver-gray glass suspension bridge is light and clear, and looks particularly vivid in the sun. We set up the plane and looked at its attitude from the other side.

A person walks up alone, looking far into the distance, and seeing green everywhere, as if the entire sky and earth belong to you. Be more courageous, hum a song, run on the plank road, and enjoy the shuttle between the jungles. I am very decompressive.

After getting off the overpass, it is a very interesting "floating in the sky".

Playing in the water in summer is the happiest thing. This "floating in the sky" waterway is also made of transparent glass and looks as if it is suspended in the air. The two of them were in a boat, put on raincoats and rainpants, got on a kayak, and walked down the glass waterway.

Maybe we are afraid that the speed will cause danger, but we don't put much floating water now, so we are often stuck in the middle and can't get down. But fortunately, there were still friends coming down behind. When they hit us, we flew down like a fly ~

In the scorching summer, it's really enjoyable to have fun touching the water.

If you like to play in the water, in addition to the Chuiyun Tongtian River, there is also another scenic spot not far from the scenic spot,"Langshi Golden Beach", which is also a good place to play in the water.

Bamboo raft rafting, outdoor expansion, starry sky camping, wild barbecue, and farmhouse stove. When you are lucky, you can still see dragon boat races here ~

The heat has arrived, and children in the south want to find a cool place to escape the heat. So, what you can't miss is this impressive, playable and photographed cloud-covered Tongtian River.

So, do you think this scenic spot is suitable for visiting in summer? If you had the opportunity, would you come to Chuiyun Tongtian River to experience it? Everyone is welcome to leave comments!
