Beinn Dearg, the Red Hill, reaches 483m in the Knapdale hills behind Lochgilphead. Iron-rich rock gives the summit slopes their characteristic warm hue, especially after rain.

Standard route
heather moorland 60% · grass slopes 25% · schist outcrops 15%
A short approach from the B841 by the Crinan Canal climbs heathery slopes and small schist ribs to the summit. Around 2 to 3 hours suffices for a return trip when the line is well chosen.
Terrain
Open Knapdale moorland — heather, bracken in summer, and broken schist outcrops near the top. Drainage is poor in places after wet weather.
In winter
Too low for reliable snow cover but exposed to coastal winds. Frozen bog underfoot is the most likely winter hazard.
