Most Westerly Point
The Point of Ardnamurchan is the most westerly point on the British mainland
Situated near the settlement of Kilchoan on the remote and rugged Ardnamurchan peninsula, the point is marked by the 36m high Ardnamurchan Lighthouse. The drive itself is considered extremely scenic, with the route becoming a rugged single track road at the end.
The lighthouse was built in 1849 using granite from the nearby Island of Mull. Although now completely automated, the tower remains fully operational and still plays a vital role in ensuring the safety of all passing ships.
More information about Ardnamurchan Lighthouse can be found at www.ardnamurchanlighthouse.com.
The main keeper’s buildings have now been converted into a visitor centre with various different exhibitions. One of which was provided by Lochaber Geopark with a series of interpretation panels explaining the formation of the local landscape aimed at young children. There are also a series of corresponding panels for adults.
You can also visit the tower on a guided tour and learn about the history and workings of lighthouses.
There’s a charming cafe and shop where you can sit back and enjoy the stunning views.

The lighthouse stands on a grey, coarsely crystalline rock called gabbro. It was formed from magma that had risen from deep within the Earth. It has the same composition as basalt, but because it cooled much more slowly within the Earth’s crust it developed bigger crystals. This gabbro makes up much of the coast around the western tip of Ardnamurchan, as well as the hills to the south of Achosnich. It was once part of the chamber of magma that fed the second volcano to erupt on Ardnamurchan.
When the volcano stopped erupting, the magma remaining in the magma chamber cooled and crystallised slowly to form gabbro. We only see the gabbro today because more than 2km of rock has been eroded from the original volcano.
