I reserved all 3 of the group sites for our family camping trip July 24-30. I reserved all 3 sites because Recreation .gov says that group site 14 will hold 5 trailers and 25 people, the same with 16. 15 is supposed to hold 10 trailers and 50 people. These are highly exaggerated estimates so I reserve all 3 so others don't come and be disappointed because there is not room for as many as they anticipate. I recommend that anyone anticipating reserving these group sites, visit the campground so you know what reality is. This year there was no potable water available and I was not notified of this until we were there and it was too late to change plans. I love the campground, especially group site 15, but it is expensive to reserve all 3 sites just to keep it a pleasant experience for our family without others coming in and overcrowding the area.
