Glentrool

As you go, listen out for the high, piping call of tiny goldcrests as they flit through the conifer canopy. These busy insect-eaters are the smallest birds in the UK.

Winding through the woods you'll see the poignant Martyrs' Stone, where six Covenanters were murdered in 1665 because of their convictions to obey God rather than the King. Enjoy spectacular views down Loch Trool as you return through the forest, passing the pretty Spout Head Waterfall.

You can extend this trail to make a full day out by joining the Loch Trool Loop (green waymarkers) at the bridge over the Water of Trool. This will take you right round Loch Trool and past the historic Bruce's Stone.

Listen hard and perhaps, above the gentle lapping of the loch, you might also hear the ancient roar of combat. Here on the Steps of Trool, a bitter battle was fought between the English and the Scots during the Wars of Scottish Independence 700 years ago.

This trail starts at Caldons car park, at the western end of Loch Trool. From Glentrool Café, follow signs to Loch Trool and Bruce’s Stone. After about 1½ miles (2.5 km), turn right into the car park. You can extend this trail to make a full day out by joining it with the Water of Trool Trail (yellow waymarkers) at Caldons car park. This takes you through the forest to Glentrool Visitor Centre then back through the glen along the lovely Water of Trool.
