|Gwern-Y-Cleppa is easily seen from the M4 when travelling from Newport to Cardiff (can't be seen in the opposite direction). Just after Junction 28 there is a footbridge over the motorway, just after going under the bridge you will see the back of a large road sign on your right (giving info for motorists heading towards Newport). As you come alongside the sign, look to your right and there it is. Be careful not to crash though!!!
