this spot isnt as good as asking around the rest stop but after 10 minutes signing for dublin a lovely woman from belfast brought me to saggart so this spot works too in a pinch. i wouldnt sign from the onslip though it looks too sketchy to walk to. signed for dublin

Walk along Dungiven Road and there'll be enough space for cars to pull in. Good for rides towards Belfast.

Take bus B to Belfast and ask for the last stop in Belfast. Cars go fast here but their is hips of traffic. You could also walk back to the red light where people can have a better look at you.

For hitching Enniskillen/Belfast direction

It's a good place for hitchhiking to the Dublin city centre, but totally senseless for Belfast directions (even though motorway sings say differently). Three cars stopped us during an hour and told us to give it up, no chance to getting from here to Belfast. At the end we had to take a bus... Anyway, cars drive fast, but there's a plenty of space to stop. So make a big sign. Also a lot of taxi drivers drive around and they think and thumb up means we want taxi, so try to not hitchhike them :)

Stand at traffic lights and approach stopped cars. Great for Belfast and other places north of Dublin.
