Not just group and horse camps
These sites are first come, first serve which is good and bad. Doesn't fill up like some of the year round sites right by half dome and it's really not that far if you want to get some awesome views.
Good space for tents and you're semi secluded from other campers and not as many RVs/Trailers as some of the other campgrounds.
Decent access to drinking water and each site has tables and fire rings, no RV hookups (another reason you have more "campers" and it's less noisy at night).
