Stage 4 of the West Highland Way covers 22.0 km from Rowardennan to Inverarnan, with 512 m of ascent and 511 m of descent. The highest point is 146 m. Allow about 6.5 hours of walking, plus breaks.
Distance, climb and elevation come from the Outest route data. Difficulty and time are estimates from distance and climb; your pace will vary with heat, pack weight and photo stops.
Campsite on the trail at Inverarnan with tent pitches, hiking huts, bell tents and chalet rooms, a bar-restaurant and a camping shop. Closed for the season from 12 October 2026; 2027 bookings are open.
Historic inn from 1705 on the A82 at Inverarnan, about 300 m across the river from the trail, with rooms in the inn and a newer lodge across the road. Food every day; book well ahead for summer.
Bunkhouse about 800 m uphill from the trail at Inversnaid, with seven basic rooms, camping, a bistro and a bar. Check opening dates before you go.
Large hotel on the trail beside the Inversnaid waterfall on east Loch Lomond, used mostly by coach holidays; a limited number of rooms are sold for bed and breakfast. Walkers often stop at its bar.
Checked online in October 2026. Places marked "listed by a tourism directory" are on OpenStreetMap or a local tourism listing but could not be fully confirmed on their own website. Many hostels and campsites open only from about April to October, and small villages have few beds: book ahead for May to September.
Emergency: call 999 or 112 (ask for Police, then Mountain Rescue). Non-urgent medical help: NHS 24 on 111. Emergency & health guide
