It's a beautiful place and a dreamlike landscape. What a shame the shelter isn't working. These politicians we have don't do a single thing right.

The current town of Tarna was built after the Civil War since the original town was destroyed in the war. The distribution of the houses today is curious, with two large streets that divide the town into three. Some of the most beautiful routes in the Redes Natural Park start from Tarna.

Beautiful waterfall to see. "Tabayón" is synonymous with "waterfall" in Bable. To go up to the waterfall there is a slightly steep slope of loose stones, so especially to go down you have to be careful not to slip.

Caleao is a small village of houses perched on the mountainside, steep and cobbled paths, and intense green. Above the town, the landscape is made up of high mountain valleys, beautiful beech forests and animals such as wolves, deer, wild boars and wild cats. Higher up, huge stony and snow-capped peaks rise.

The tunnel was carved by hand through which in the past the animals had to be unloaded so that they could pass through. Now, it is somewhat wider and allows tractors etc. to pass. Without a doubt, it is the most spectacular area of the route, with impressive vertical precipices.
