A fairly tough 18 mile ride over Ratagan Pass to the village of Glenelg
From Shiel Bridge follow the minor road, first southwards then westwards, round the shore of Loch Duich. After a mile take the left fork which almost immediately starts climbing up through the forest towards Ratagan pass. As you get higher and the road starts to switchback the views open out and the are particularly good views to the Five sitsers of Kintail. The road briefly exits the forest before re-entering it as the descent to Glenelg begins. There's a good run down to the floor of Glen More which is then followed to the village of Glenelg.
For those with more time this route can be extended by following the road through Glenelg to the Glenelg Brochs (an extra 5 miles return) or even to the village of Arnisdale which nestles below steep mountains on the shores of Loch Hourn (an extra 20 miles return). Whether you go to Glenelg or do one of the extensions the only way back is to return by your outward route.
