It sounds like you have all of the right directions.... just past the 16km marker on the road past Silver Lake look to your left & there's a brown & white sign for Eaton Lake. Turn into it & there is a little bumpy road that leads off and to the right (parallel to the main road) . Follow this to a small parking area. Once parked look towards the mt. to see a atv type track heading up, but not too steeply. There is another brown wooden sign, can't remember what it says but there was a private sign tacked on it about someone's lost cell phone. Carry on past this, track gradually narrows then swings left & up, away from the creek before eventually returning for your first log crossing. The logs are obvious, have been crosshatched & have a railing of sorts. There is one crossing that is poorly marked, the log has been washed away and you kind of have to hop & skip across debris but the trail is quite obvious on the other side. This more obscure crossing in quite a bit further up and goes to your left as you're heading up the hill. I hope you try again, it's a great trail, one of my favourites. I live quite close by so message me if you're trying again and maybe I could show you the way.
If I don't try, I've already failed.
