On Friday, 27 October we visited Buila Vanturarita National Park. The park is comparatively small but it has vast diversity of plantation and forms of relief. We met the director of the park and the biologist who is working there. The main problem of the park is pollution with plastic. We should find a solution for this problem. There are no trash bins in national parks, so people should keep the trash until the end of their visit of the park. Also the smokers should keep the rests of the cigarettes. We visited a cave with bats. They make very high specific sound. In the cave the temperature was higher than outside. In summer time in the cave is cooler than outside, in winter time – warmer. This fact is very good for travelers, they can spend a night inside the cave. We used our mobile lanterns (thanks technology!) to go deeper in the cave. The way was becoming narrower and narrower and we have reached the point where we couldn’t continue. But it was not the end! The cave is really deep! After that we visited monastery where the believers can go under the table 3 times to implement their pray. Religion is everywhere in Romania. And in the mountains it is really strong!
