Recommended by locals and heavily marketed hotel in Okpo.

Being largely a resort island, large hotels are everywhere.

Budget
A jjimjilbang exists in Okpo roughly halfway between Geoje Museum and Okpo Port. Naturally, expect sauna access, cotton pyjamas and a bunch of blankets to sleep on the heated floor. Look for the neon sign. Price is 7000 won a night, and the sleeping facilities are larger than usual.

Midrange
The townships all contain the usual array of motels. Further to this, outside of the larger towns, minbak homestays for tourists are scattered around the coast, often attached to restaurants.
