Hi Mary, St Johns is an area in the high street of Swansea, now it's known as St Mathews, That aside the info you seek is as follows........ Out of High street train station turn right St Mathews "St Johns" is around 100yards up the road on the left hand side. continue up high street to traffic lights turn right to next lights "10 Yards" turn left onto Llangefelach road travel around 1 mile to Pentrestyll this begins just after railway bridge with Maggie Dicks "pub" on the right As for Rhossilli this is in the Gower and is at the far end. which will take sometime to get to as you have to negotiate long narrow winding lanes. but is well worth the time as it is a beautiful part of the gower. Hope this helps Brian Davies Swansea
