Enter the Mars base in the hinterland of Tunisia's Sahara desert.

It takes three hours to drive from Douzel, pass through jared Great Salt Lake, the third largest salt lake in the world, and reach Duz, the gateway city of Tunisia's Sahara desert. When I changed into a jeep from Duz and started to enter the Sahara desert, my father said, is the desert here different from what I imagined? There are also many desert plants growing in the sand, which look like seabuckthorn or Salix from a distance and flourish. The first hour's drive was on the highway in the desert. Although the road is full of sand, it is only bumpy and the speed is not slow at all.

When I saw a building in the distance, the desert highway came to an end. When I remembered the cell phone signal, I saw that it was a national park. It turns out that this building is the gate of Jaber National Park.

Shuailong asked, this is a national park set up to protect desert animals. I vaguely feel that the desert surrounded by fences is greener. Our jeep turned right at the gate and began to drive into the vast desert, but it kept driving along the fence of the national park, because the ground here was more similar to the Gobi Desert where we used to run. There are no roads here, but there are roads everywhere. There is only one closed cafe on the roadside, and it is speculated that the cafe is closed because of the off-season.

After driving for nearly an hour, I saw a high hill in the distance. My father muttered, can't we drive up that hill?

But after 20 minutes, our second car was stuck in the sand dune many times, fully charged, refueled, stopped at half waist, backed up ... again ... repeated three times, but still failed.

Later, my mother-in-law said that their driver was sweating, and the whole car got off one after another. Later, the old driver of our car changed, surveyed the surrounding road conditions, diverted to other routes, and finally drove on the sand dunes. There is no danger, cross the sand dunes and walk all the way to the hinterland of the desert.

There is a big mountain in the distance. I think this should be the camp. Sure enough, after seeing another cafe, I turned a corner and the camp was low on the sand dunes.

So what about the Mars base in the desert, which is three hours away from the nearest city, Duz? Expect us to find out. On New Year's Eve, what do we do at the Mars base to celebrate the New Year?
