Take your geographically required route to Jcn 42 on the M4 and then follow the A483 and then A4067 west to Swansea Bay.
To Swansea map
To the Scout Hut:
Follow the A4067 driving east to west around Swansea Bay turning right, just after the University, onto Sketty Lane (looks more like a dual carriage way) i.e. the A4216.
Please see the Killay map for the route from the A4216 (bottom right hand corner of said map) to the scout hut.
Nb the scout hut is available from 3pm Friday 12th November until whenever on Sunday 14th November.
To the Castle:
Again use the Killay map heading towards Derwen Fawr Road (bottom right hand corner of said map) Follow this road, turning right, back onto to the A4067 (Mumbles Road).
From the A 4067 turn right onto Newton Road (B4593), just before a pub called the White Rose, and you will see the castle up on your right at the 1st and 2nd turnings on your right. Now your mission is to find somewhere to park, interesting but possible.
Any problems give Kate a ring on
