M5 to Exeter, then A30 towards Bodmin. Just after Launceston take A395 for 11 miles, turn left onto A39 for 1.4 miles then turn right onto B3314. After a further 1.4 miles go right and immediately left still on the B3314. Continue on through Delabole, past St Endellion and turn right signposted Polzeath, then right to New Polzeath.
Entering New Polzeath turn left into Tinners Way (opposite the first buildings on the right hand side) then IMMEDIATELY right between stone pillars into the private road called Cliff Lane. Follow this down around a sharp bend to the left and Rosanagh will be found on the left hand side coloured pink about 5 properties from the bend.
