Senda del Oso

The Senda del Oso (Path of the Bear) is a popular cycling and walking track along the course of a former mine railway, southwest of Oviedo. The most popular stretch runs 20km between the villages of Tuñón and Entrago. With easy gradients, it runs through increasingly spectacular valley scenery into deep, narrow canyons, with several bridges and more than 30 tunnels. It also offers the high probability of seeing Cantabrian brown bears in a large enclosure at Cercado Osero (which is probably as close as you’ll ever get to them), and it’s a fun outing with (or without) the kids.
