Approaching on A55 (North Wales Expressway) take the A5 ramp tp Bangor/Bethesda. Follow the signs for Llanberis ( A4244) At the next round about take the second exit on to B4366. At the next cross roads turn left ( immediatly after Gors Bach pub) continue on for 1.1 miles. slight right at the fork and the farm is the white gate t in 0.1 mile on the right.
From Llanberis on the A4086 at the Glyntwyrog pub in Llanrug turn right. go down the hill, past Pen y Bont Pub, over two bridges, continue up the hill to a staggered junction. Look for lane slightly to the left, between two houses. You are essentially going straight on so do not go down the lane to the left. Go up the lane to top of hill, the white gate for Coch Hir farm is on the left, just past a large farm house.
The post code is LL55 3PR.
Google has just changed the post code position so it now shows as Glascoed Hall (see map below where there is a caravan park) please note that Coch Hir Farm is on the lane to the right where the blue circle is.
