The River Lednock cascades out from a rocky gorge in the atmospheric tree-clad amphitheatre known as the Deil's Cauldron. This excellent circular walk from the attractive village of Comrie, just outside Crieff, visits the Cauldron as well as having an optional ascent to the Melville Monument, an obelisk on Dun More hill that is a fine viewpoint.  The Deil’s Cauldron trail is a low-level walk, so you don’t need any special gear. However, you’re reasonably far away from the village of Comrie - so waterproofs are a must (just in case). Also this is a forest walk with exposed tree roots, rocks and muddy sections in the rain, so make sure to wear sturdy walking shoes or hiking boots.
