Dates are approximate. 

Day 1 plan is to drive to the Semaphore Lakes trailhead and car camp. 

Day 2 will be an early start to the lakes, and then traverse the peaks in a single push back to the car. Pace is expected to be relatively fast. 

There are lots of good trip reports out there. This one in particular has a good description of the route:
