It's a moderate hike that can easily done in a day.
Right at the start of the hike you will have to wade across a creek and will get your feet wet so bring a pair of dry socks or whatever.
Most of the elevation is on the way up to the Sunrise Lakes junction. Once you get there the trip to the last punch to the top of Clouds Rest is pretty easy. Once you get to the next junction at about 9100 feet the way to the crest is not too bad. The trip back is mostly down hill except for the middle part where the "flat" has some ups and downs of a couple hundred feet. There is one short stretch of trail at the very crest that may make you want to be on all fours. When you get near the crest the trail separates into a trail that goes to the south around the crest and the trail that goes over the crest.
Go back down the same way you went up as there isn't a good trail loop for a short day hike unless you want to go down to the John Muir trail and out past the Sunrise Lakes. This is doable in a day but it will be about a 20 mile day.
Take at lest two liters of water. There is water about one mile after the Sunrise Lakes junction.
If there is any weather brewing can the trip. Lightening likes the crest of Clouds Rest.
If it is a clear day you will want to spend some time up there so be ready to eat lunch there.
Do not forget a couple of cameras and a small tripod.
