Eildon Hill is just south of Melrose in the Scottish Borders and looks out over the town. People often call it "the Eildons" or "Eildon Hills" because it has three peaks.
This igneous rock formed from volcanic activity that occurred 350 million years ago.
Later, the Romans built a signalling station on the same site as the hill fort.
The hills are part of the Eildon and Leaderfoot National Scenic Area, one of forty such areas in Scotland. These areas are chosen for their outstanding scenery and are protected from unsuitable development.
People say Eildon is a "hollow hill," and it appears in the legend of Thomas the Rhymer. Some think Thomas actually went beneath the hill, and part of the ballad takes place nearby.
Charlie climbed one of the peaks. After he made us coffee, I climbed the other one.
