Out of the hundreds of campgrounds I've seen in my life, this one is the most beautiful to date. We camped here at the end of day one, of a two-day hike to the summit of Mt. Langley. It's about a 6.5 mile hike in and is above 10,000ft elevation. Took us about 3 hours to hike to Cottonwood Lake #5, going at a leisurely pace. Some people do the Mt. Langley hike in  a single day, but we wanted to give ourselves time to adjust to the altitude. I'm so glad we did, because the overnight camp at Cottonwood Lakes was an adventure in and of itself. We saw marmots and even a bighorn sheep! My brother caught multiple Golden Trout while fishing at Lake #3 and #5. We considered a few different spots for our tents, and ultimately decided to camp a few yards away from Lake 5. There was no wind there all night, whereas some spots closer to the main hiking trail were already getting windy. The ground near Lake #5 was pretty plush, not rocky, and somewhat level. We saw some even better spots near Lake #3, but those were already taken.

Hike to Mt. Langley: If you camp here, you've already hiked about 6 of a ~20 mile hike. Day two you hike ~4 miles to the summit, then 10 miles back to the trailhead parking lot.

Permits: you will need to get an overnight permit for Mt Langley hike at recreation.gov in advance. We grabbed three a couple weeks before our planned date. If you are planning to fish, you will also need a permit for that. All permits should be printed in advance.

Food: You are required to use a bear canister for overnight camping. Your toiletries, wrappers, trash, and food must fit in there, so plan accordingly. We used Bearvault bv450, for 3 people, and barely fit everything in there.

Water: You can refill your water from the streams along the first six miles of the hike or at the Cottonwood Lakes. There are no natural water sources between Cottonwood Lakes and the summit, so make sure to fill up before you depart the lakes. We boiled water for cooking dinner, and used iodine tablets for drinking water.
