After 2 miles turn left at Jet Station, signposted to Veryan. Continue on this road to Veryan Green, (do not turn off as some sat. navs indicate!). As you enter the village you will see Veryan Galleries on the right and then the two Round Houses. The Right Roundhouse B&B is the one on the right!
From the centre of Veryan:
Take the road towards Tregony past the village pond on your right and continue uphill into Veran Green. Pass the green on the left and see the two Round Houses straight ahead. The Right Round House is now the one on the left.
