"Ben Gullipen comprises a hike upwards from around 60m above sea level to 414m. A fascinating fact is that Ben Gullipen is classified as a “Tump”, which is a hill in the UK with at least a 30m drop from the summit to the nearest shoulder of land. It is also situated on an open parallel ridge. These type of ridges are a direct result of the geological activity along the Highland Boundary Fault, which makes the natural and cultural transition between the Highlands and Lowlands."

This walk is a good challenge for those starting out on the hills. The paths are very good with just a few mildly steep sections which makes this is a perfect beginner hill walk. No one will be left behind. On a good day, the views at the top are spectacular!
