Mirror Lake and China Meadows are good examples. There are countless others less crowded or with slightly different character. What are you looking for? Trial Lake is good for fishing. Wall Lake is a great fishing spot, in addition to spectacular scenery and a short hike.
Mirror Lake is good scenery and good car camping, right off the highway. Crowded, though.
Christmas and China Meadows host an incredible array of wildflowers in season. Wildlife in abundance. Birds flocking through. And always hoards of chipmunks and squirrels scurrying around. You might spot an elk or some deer, or even a moose!
