Avenc del Grimp

Going along the BV-5207 road from l'Esquirol to Tavertet, when we reach kilometre 11.66 right at the height of the pont de Pla-sa-Riera that crosses the riera de Balà, we must go down to the river where we will find the mouth of the cavity about 20 metres further down from the bridge, in the river bed and next to a large block before the small waterfall on the right bank of the riera; this block on its lower part forms a curious and wide tunnel through which the riera also passes when it carries a good flow of water.
