Isabu Cruise is a sightseeing boat operator in Yeosu that runs night trips on the sea and shows a fireworks display. On Friday, Saturday and Sunday evenings the fireworks last about five minutes, while on weekdays the trip is built around night views and performances. The 2 p.m. boarding course circles the area around Yeosu and takes about one hour, with a magic show on the first deck and busking on the third deck. Weekends draw a large number of passengers.
