Huerta Cave

Highlight • Cave

A really nice stretch of road. It is not usually very busy with motor vehicles, even so, be alert at every curve: with such beauty it is easy to get lost and change lanes.

Senda del Oso: San Andrés - Entrago

Highlight (Segment) • Trail

Being the old route of a train, the slopes are not very steep and it is a very affordable route. Very beautiful area that is worth exploring even if you go off the path itself

Before renting a bike from the "Oso goloso" rental shop in Proaza, you should know the following: the gearshift on the mountain bikes (without mudguards, bell, or luggage rack) is absurdly intentionally locked so that, out of a hypothetical 18 gears, you can only use 4 in the middle range (so the chain doesn't come off, hahaha). After you pay and sign, they'll explain this to you. However, this is completely unsuitable for riding the Bear Trail, especially the rather steep eastern variant with its very poor surface. Even with good fitness, you'll often have to dismount. Apparently, there's another rental shop in Proaza...

In Santa Marina there are some steps that connect with the section of the Senda del Oso in the municipality of Quirós, perfectly conditioned in the valley of the river Trubia. In autumn the trees are colourful and the warm lights of the most suggestive season of the year envelop the landscapes in a very seductive luminous effervescence. Bárzana is the capital of the municipality of Quirós, it is on the other side of the river, like many villages along the route. The route of the old mining train runs solitary and hidden to the Valdemurio reservoir, a reserve for aquatic birds and an active leisure centre. The Senda crosses the Cuevafurada gorge through an illuminated tunnel and reaches the Caranga de Abajo detour. The Teverga branch deviates to the left, this is the path we will take later on the return from Tuñón. The route continues straight ahead through the tunnels of the Peñas Juntas and Peña Caranga Gorges to the Proaza valley, where the Bear Enclosure is located. At times you can see bears that live in semi-freedom and come to the Senda Enclosure to eat. The cycle route continues through Villanueva and ends at the Tuñón Recreational Area, set up at the Esgarrada bridge. There is a fountain, benches, a children's playground and a bear sculpture. The route returns along the same path to the Caranga de Abajo turn-off and continues through the Teverga valley. On the way back you can take advantage of the opportunity to visit the town of Proaza, connecting again with the Senda at the bridge of the Hydraulic Power Station. The Bear Enclosure is still beautiful, wooded and comfortable for cycling, small villages appear, well-lit tunnels and after several curves the canyon opens up and the houses of Entragu emerge between the trees. The stage continues for a couple of kilometres to San Martín de Teverga, an important crossroads and town with all services.
