There is a coast path from Dunseverick west towards the Causeway.  I persuaded Sam (my 12 year old) to walk it yesterday afternoon.  Very windy – but dry and despite the cloud lots of hazy sunshine.  Needless to say we didn’t make it as far as the Causeway due to the “are we nearly there yet” thing.  However probably walked for nearly an hour and a half which isn’t bad and the views were stunning.
