Reanascreena is about 6km walk north of Ross Carbery. You walk right past Bonohagh, but it's one I haven't been to and it's notoriously tricky to find.

I suggest you buy Discovery map 89 and plan a route yourself. Directions on those country lanes would be insane.

You are also passing pretty close to Templebryan stone circle on you way. Ballyvackey is also just 2km off the main road just off the R599 after Clonakilty.

If you still want directions for Reenascreana I can give them (but will throw in the usual disclaimers :-)
