The hotel is located in the heart of the Liébana Valley, at the feet of The Picos de Europa. It consists of two buildings constructed, in the local architectural style, from wood and crafted blocks of stone framing windows and balconies.
There was originally a single building that operated as a small hotel until the opening in spring 1980 of the present Hotel del Oso, which is made up of two buildings, the main one and the annex. This expansion allowed an increase in the number of bedrooms, communal rooms and dining areas.
Ever since it opened, the Rivas family, owners of the hotel, have worked assiduously to maintain the high quality of the establishment's services and the family atmosphere offered to guests.
