Seabank Villa on the lochside at Kilfinichen Bay is the type locality for the mineral mullite.

The A849 to Bunessan and Fionnphort runs along the southern shore of the loch and there is a turn off in Pennyghael to Carsaig Bay.

The orange colour represents the top surfaces of the flow, weathered by the tropical climate of 60 million years ago.

There is a fossil tree, with a cave to its right, a large boulder on the shore just below, and a small area of columnar basalt on its left.

Just beyond the tree, there is a black sand beach, and there are in the basalt shoreline slab some older boulders overwhelmed by the lava flow of 60 million years ago.
