Take the A30 from Penzance to Lands End and after 4kms turn left on to the B3283 through St.Buryan. Follow the road for a further 3kms and at the hamlet of Treen turn left and continue to the end of the road which ends in a large field which is used for car parking. Then just follow the track past the campsite to join the SW Coastpath - go straight down for Pedn Vounder.
An alternative way to get to Treen from Penzance is to take the B3315 from Newlyn and Mousehole which joins the road from St.Buryan.
