From Drymen, the main line climbs Conic Hill, one significant ascent on the Drymen–Rowardennan stage. There’s a lower alternative, but the summit earns the climb with a view over Loch Lomond’s island chain, which follows the Highland Boundary Fault. It’s the best spot to frame the islands against the water. After Balmaha, the Way stays close to the loch through oakwood and past campsites to Rowardennan.
Rowardennan to Inverarnan is the slow day. The route starts on forestry track, then grows rougher north of Inversnaid: roots, boulders, rocky steps and repeated short climbs make the shore much slower than the mileage suggests. At Inversnaid a footbridge crosses Snaid Burn as it drops into the loch. Farther on, a small beach opens a view to Island I Vow; the path then reaches Blarstainge’s ruins and Beinglas Farm before Inverarnan. Don’t count the Rob Roy’s Cave spur as part of the Way; it’s a separate slippery scramble.
