More wealthy Chinese adventurers have scrambled to get to Antarctica during this Chinese New Year holiday season, with the country's biggest online travel agency reporting a sharp rise in bookings, which can cost more than 200,000 yuan ($29,150).

Du Jie, a 29-year-old Beijing traveler, took a trip to Antarctica for 10 days in November. In Antarctica, he tried a polar plunge, jumping into icy water, while hiking the snowy mountains with other cruise members.

"It's nice to see animals such as penguins, seals and orcas living in places where they truly belong," he said.

Meanwhile, with more travelers visiting Antarctica, there are concerns about environmental protection. The management teams of cruises usually require tourists to leave behind nothing and take away nothing from the continent, and they said tourists need to further understand the need for environmental protection.

The best period for traveling to Antarctica is between November and February, which is summer there, when temperatures in some areas can reach between 0 C and 10 C, according to travel agencies. The period, which covers China's Spring Festival break, has become a peak time for Chinese to travel there.
