For anyone interested in visiting the area, here is the basic mileage breakdown from the Symmes trailhead:
TH->Shepherd pass 9.5 miles
Shepherd->Wales 9.5 miles via Rockwell pass & WLB
Rockwell pass is another 2.0 miles from Shepherd, and the first lakes in WLB are one more mile, so it's around 12.5 miles to WLB. I did it in one day after hiking 8:20 hours, or approx 1.5 mph.
If you stop @ WLB, then it's only 6.5 miles from there to Wales. While there is an old, partially maintained trail up Wallace creek, it's easy to traverse x-c up the watershed by simply staying between Wallace & Wales creeks, which are less than .5 mile apart. That's the way I proceeded, taking 4.1 hours or 1.6 mph.
To return, simply retrace your steps. I decided to hike the entire way back without stopping @ WLB, or 19 miles. It took me exactly 10 hrs (from 7am-5pm), for an avg of 1.9 mph.
To recap, 1/2 of the hike is via trail from the TH to Shepherd pass. Thereafter, it's all x-c to Rockwell, WLB & Wales. The x-c is very pleasant, with both the Wales/Wallace & WLB watersheds providing easy navigation by simply following the respective creeks up/down the meadows:
Wales creek - just follow the water (note Wallace creek right of shoulder):
Wright creek - just follow the water:
The entire area is really spectacular - thanx again to Mav for putting the trip together.
* Note - My base pack weight was 10lbs + 5lbs of food/water. So going in, my pack weighed 15 lbs, while leaving it was only 10lbs. As a result, trail times are essentially day hiking speeds.
