We took this tour for us to get near to inheon airport. And surprisingly, the places we visited was very pleasant. Although we were drained for the past 5 days of our stay in Korea we found ourselves enjoying our last day. The cave we visited was so cold inside that leaved the feeling that you are in aboard. hahaha. Visiting the sea at wolmi island, walking along with korean families, because it was saturday, we had seen crowd. The last visit was the Railbike. this is our 2nd railbike experience. We like the wind, cool and healthy. hehe
