Things to do in Igari anchor observatory

Since it was Monday, there were no bus tours from Busan to Pohang. So, we took a taxi. It didn't rain, the cherry blossoms were in bloom, and we were able to visit all the places we wanted to, which was great. However, it was a bit expensive since there were only two of us. I think a taxi would be more comfortable if there were 4-5 people.
