I have just returned from a visit, where on local advice that the Conor Pass is not suitable for motorhomes, I based myself in Tralee and hired a car and having now done that I would say that was correct (my Motorhome is 2.77m). Tourist maps also show a clockwise circulation on the Slea Head Loop, this also turned out to be correct as we witnessed a confliction between a Tourist Coach going clockwise and a Motorhome coming anti-clockwise, between Ventry and Dunquin near the Shrine. The coach driver wasn't giving way and the result was the Motorhome was damaged as he attempted to squeeze through. Doing the SHL in a Motorhome circulating clockwise would be alright, but definitely wouldn't attempt the CP. All in all worth the effort and better than the ROK IMO? There is also Motorhome parking at Inch Beach at €10 per night payable at the Beach Store.
