Directions: From Port Ellen drive up the Oa and follow the road all the way to the end. At the T-junction keep left and follow the signposted track (RSPB Nature Reserve) to the parking place.
Walk: Follow the track heading down to Upper Killeyan, but keep right before the bend and follow the well-marked signs for the American Monument. Just before you reach it there are dramatic views of the cliffs on your left. Around the monument are stunning views over the North Channel, the sea between Ireland and Islay. Return either by following the track where you came from, or by heading east to complete the circular walk. This part of the route is also waymarked. As you walk along the top of the cliffs you have more stunning views of the Oa, before heading back to the parking place while passing Upper Killeyan Farm.
