There are a number of campsites surrounding Alta Lakes and there are also other lakes nearby. Gold King Basin is a popular alternative to the most trafficked Alta Lakes, although it can see more wind than Alta. Overall, the camping experience is serene. High-altitude lakes with nearby jagged peaks and far-off vistas... it's remote, but it's worth the trip. The road to Alta can get rough after heavy rain and at the end of the season. Usually seems like at least half of the sites are occupied. It's a come-and-go-as-you-please sort of site, although I think there's technically a 7 day limit. Free.
