This is a great campground; clean, easy access, with tons of shade even though it's close to the lake which I love. It's essentially split into 3 sections (Arapaho Bay Big Rock, Morraine, and Roaring Fork). They're all essentially the same campground but they are run by different hosts. Roaring Fork and Morraine are right on the lake but have NO shade. Arapaho Bay- Big Rock is fully shaded and still only <5 minute drive (probably a 20 minute walk) to the water. 

Also, we saw a baby moose and his mama while we were here! Camped here late July and it was great weather for hiking, kayaking, and sleeping under the stars!

Please be aware that CO weather (especially in the mountains) is very prone to quick changes. Come prepared with lots of layers, weather-proof clothing, and tents that can withstand a storm.
