North entrance or south through the town?
from the north you go south following the A487, should be the only road there (assuming the roads are accurate) about halfway down it splits into two take the left option till you get to the town. then continue left around the A489 and onto the A470. Only drove it 3 or so times so might be wrong
Lol! I've only been the once by air (in a Jag - I posed, but there were no photographers there it seems!)...
