Three day trip to Tank Lakes via Necklace Valley. Started on a Tuesday and only encountered one group of three, on the way out. Bug free!
First five miles are a scenic forest stroll. The next few to Necklace Valley, however, are not pretty - rooty, rocky, muddy, wet, and steep. Not for the faint of heart, and, unfortunately, the lakes in the Necklace Valley are not worth the work - some are pretty (turquoise Ilswoot in particular) but the others are shallow and swampy.
Press on to Tank Lakes, however, and you'll be in a pristine wonderland of granite, lakes, and tarns. A very special place.
To get there, just follow the trail south to the end of the valley and keep an eye out for cairns, eventually ascending a medial moraine. It's a lot of boulder scrambling, but not too difficult if you take your time.
There is no official trail, so have good route finding skills, appropriate gear, and be in good physical condition. This area is still in good shape - if you do go, follow Leave No Trace and help keep it that way!
