Head out in the direction of La Pera and follow Route 4 almost until the Cinc Alzines hilltop is in sight. Then 50 metres before the main road heads off towards Cinc Alzines, take a left, where a small sign for the 'Variant Ocata' turning marks the way to the village of Olvan. The route then passes through a cattle gate, and the road continues westwards through the fields as far as an old youth camp, close to the river which is crossed by a footbridge alongside the shed.
The stream is known as La Riba, and supplies the village of Olvan with its water. There is a water spout nearby the road to Gironella, before crossing the bridge, at the Font del Rull. This is a popular spot to fill up on drinking water.
