To start the fourth day of our adventure, the students from both schools gathered in front of the station to catch a train to Szilvásvárad, a village near Eger. After a one-hour journey to the village, we boarded a small train that took us into Bukk National Park. There, we met an expert in ornithology and nature conservation. She told us about the different species of animals and plants we could encounter in the park.

We gathered in the teams that were formed on the first day, and for an activity, she gave us sheets with pictures of plants found in the park, with blank lines next to them. Our task was to write down the names of the plants in Hungarian, English, and Bulgarian while we walked around. After a long walk, all the teams gathered to see who had written down the most names.

When we finished, it was afternoon, and we had to return to Eger. We arrived back in the city and had some free time, during which we decided to go to the mall. As the time came, we returned to the school. There, our next activity was making sandwiches, followed by a karaoke evening, thus concluding the fourth day.
