I did this hike with my cousin just after the July 4th holiday, and most of the crowds were leaving as we were hiking in. After debating which route to take, we decided to hike the loop counter clock-wise. When all was said and done, we were glad we did.
The route up is tough but worth it since most of the elevation gain is done the first day. We spent two nights at Camp Lake and had good luck fishing at Upper Camp Lake. Leaving this, we hiked past Rawah 1, 2, and 3. This was some of the most spectacular scenery I've seen... until we hiked up to Grassy Pass. It was even better. From here, we could see Medicine Bow to the north and Rocky Mountain Nat'l Park to the south. Absolutely incredible views from this panoramic spot! We spent another night at Twin Crater Lakes, below timberline.
On our hike we saw plenty of wildlife including: deer, big horn, moose, and even a porcupine. The mosquitos were out but headnets mitigated their annoying buzz.
This is certainly a 5-Star hike for me and I'd do it again in a heartbeat.
