The road is the PMV 220-1. Driving along the road from Palma, as you reach Pollensa town on the left hand side, pass the first two entrances into Pollensa (opposite the second entrance there is a monument on the right hand side of the road). You will then come to where they are building a new roundabout (lots of cones at the moment). Here you take a right hand turn (signposted Alcudia) onto the PMV 220-1. Once the roundabout is finished this should be much clearer but at the moment very easy to miss (the PMV 220-2 will also exit this roundabout and is signposted Alcudia so be careful which turning you take). Drive along this old road for just over 1km and turn onto a bumpy track on the left just after the 5km stone marker. (5km marker here as the road is measured from the opposite/Alcudia end and 6km in total). C'an Vidalet is along this bumpy track. Sounds it but not too difficult to find. Good luck!!
