The Royal Scottish Arboricultural Society made a visit in July 1925, and described Puck's Glen as a striking example of how man, working hand in hand with nature, has made what was once a bare hillside ravine into one of the most lovely walks imaginable. Starting near the sixth milestone from Dunoon on the old main road to Arrochar, the bridle-path by the stream which the Ordnance Survey map calls the Eas Mor, but which is better known as Puck's Burn was soon hemmed in by steep banks, while growing on their slopes are conifers of a dozen or more varieties, rhododendrons, and many of the rarer species of ferns. The path follows the stream through the whole course of the ravine.
