I've climbed Colldejou twice, well almost! Last March I went to the top in clear, very cold and windy weather, stayed for fifteen minutes then retired chilled but thrilled. Looking West from Salou, Colldejou is the big roundish mountain above the Port. The name refers to the town of Colldejou which means "The Pass of the Ox Yoke", "Jou" being Catalan for Yoke, and Coll as in Scotland meaning a pass. The two adjacent passes look like a Yoke from afar.
Colldejou, and the road, from the top.
You can drive up to the town and park then take the well signposted track which leads to Llaberia and then Coll de Guix. (2kms) From Coll de Guix take the right turn through the woods which then leads steeply up the hill, through the treeline and out onto scree slopes to the flat top. It's a fairly steep 400 m climb but not bad if you take it slowly. In fact, the top of the hill is a long oval lying East West and is of weathered limestone. There are many strange features, the most notable of which is an old fort structure at the East end. There is a shallow pond in the centre of the hill, and what appear to be ruins of a chapel or lookout at the western end. More investigation needed.
On a clear day the views to the coast and the windmill farms to the North are magnificent, but be aware of sudden temperature changes. I quit short of the summit yesterday as it looked like a temperature inversion hanging over the top and I was ill prepared for that. It's also quite a demanding climb so wear good fell boots and avoid fog as there are some very narrow ledges to negotiate with scary drops.
How to get there: Check out the instructions on www.gencat/palaurobert . Head for Montroig del Camp, avoid the centre and take the C322 towards Falset. About 14 kms on you come to Colldejou. (it's lovely road. If you just want a nice drive, carry on to Falset and come back via Mora) In Colldejou, park by the bus stop at the foot of the town and walk up past the church, always upwards then out past a wooden chalet where the signpost points you to Llaberia, then Coll de Guix. At Coll de Guix watch for the signs to the right (faded paint) which point you to a level trail through the woods. Take a litre of water, some sandwiches and binoculars. Plenty of eagles and red kites around on mild days. You might just see a mountain goat too.
