Idi Guest House is a guesthouse in Sehwa-ri, Jeju, close to Sehwa Beach. The owner prepares a Korean breakfast with a different menu each day, and at 8 p.m. runs an oreum starlight tour with photo shoots against the stars and the Milky Way. Guests can swim at Sehwa Beach and return right away, and the area around the guesthouse is quiet at night. When the weather is cloudy, stars are hard to see on the starlight tour.
