I'm thinking climbing Ben Lui from Tyndrum next summer. I'm looking for a walkers route to the summit which doesn't involve scrambling. My proposed route is Tyndrum to River Cononish picking up the good track to Allt an Rund. Cross the river and head for Allt coire Laoigh but not crossing it. Walk beside the river to Coire Laoigh to the saddle Ben Lui shares with Ben Oss. Turn right for the summit of Ben Lui. Is that route manageable for a walker? I don't have a head for heights so narrow ridges I would have to avoid. Is crossing the allt an rund easy enough or does it depend on how much rain there is? Would appreciate any feedback on this route. Thanks, Henry
