Great stuff Mick, it's a tough climb up across the 'one mans pass' on Sliabh Liag,
they have built a car park and toilets etc at the bottom of the access road and you have to pay to go up, they have shuttle buses now for tourists,
they still let bikes up for free though if you get a friendly local on the gate, I hardly bother going up there now though, there are some fantastic roads not on the WAW at all in Donegal.
There's a road behind the mountain called the Pilgrim's path, it's unpaved and tough going but you can ride a bike right up to the back of the mountain and the one mans pass is just above you, suit something like a crf 300 better though.
