Today we visited S’Airde Beinn, commonly known as Crater Loch.

Contrary to popular belief it is not a volcano, but rather a volcanic plug – an intrusion of volcanic dolerite rock (similar to basalt) into the surrounding lava plateau. The crater is a glacial depression that has since filled with water.

Far from being the tallest mountain on the island, it does offer superb views all over the northern part of Mull and beyond – Glengorm (below), Ardnamurchan, Tobermory, Ben More and Caliach Point.

And there’s a geocache up there too: The Crater Loch 🙂
