Tried to go Grizzly to Ladybird the other day. Ground was frozen with a cm of new snow and that was enough to turn us around. We went the other direction earlier this summer and it's a great loop for you kootenay folks. A week too late to give this one a try. It's a bit steep and technical getting to the ridge from the Grizzly side which is why we wanted to give it a try to see how ridable it is. Think it should go ok for 400's or smaller with experienced riders. It is a fairly easy ride going from Ladybird to Grizzly on quad trails. Another great loop in the Norans range. Give it a go.
