Last weekend we backpacked to ribbon lake via the ribbon creek trail. There is a very clear intersection where left goes to ribbon falls and ribbon lake, and straight goes to memorial lake. Not knowing the area well at all we went straight and got to the 2nd lake before realizing our mistake. I think it took about 3 hrs to get to the 2nd lake no ropes need to that point. We had full backpacks on and didn't have any issues. So we had to backtrack to the intersection and then proceed on the correct trail. Our day was supposed to be about 11 kms and 4 hours but ended up being about 20 kms and 8 hours. The following morning we headed up over guinns pass and out galatea trail. Enjoy memorial lakes. Beautiful area!
