Seahan is one of the four hills in the so called ‘Circuit of Kilbride’. Kilbride Rifle Range is an Army range on the Dublin/Wicklow border and it is nestled in a valley surrounded by Seahan, Corrig, Seefingan and Seefin. In fact these summits mark the boundary of the Rifle Range (Although strictly speaking the boundary passes within 150 metres of Seahan’s summit)
A minor road leads from Bohernabreena in Dublin past the entrance to the Range. Seahan can be reached from this road at O073200 A for example. At about 480 metres altitude this leaves a 160 metres climb to Seahan. There are remains of several megalithic tombs on Seahan. There are also good views towards Dublin and across to Seefingan and Seefin.
Because of the rather featureless nature of these hills it could be easy to become disoriented in poor weather which could mean an unintended descent into the Rifle Range. Seahan itself is generally ok underfoot, but the wider circuit includes some very wet and boggy cols. Also scramblers and quad bikes have churned up the bog in many places.
