We have camp sites for families or just groups of people to use for holidays. So have additional facilities but many are just a field and washing facilities and possibly a shop to buy food and a social club for evening entertainment.That sounds awfully like the RV/Tent campground I go to once a year in July, here in Montana, up in Glacier International Peace Park, which stretches from northwest Montana up into Canada at the province of Alberta. :)
I camp at a campground just a little drive south of the town of East Glacier, which is the eastern gateway into the park.
The tent facilities are in the pine trees, and the RV's and campers set up in two large open fields (which are also horse pastures). It also has a community center for social activities, a shower facility, and there is a small shop at the main office.
Very similar to our campsites except yours is obviously in much more beautiful settings.
Ours are often just an old field that sometime in the past a farmer did not have a use for anymore or some waste land near the coast which has been turned into a camp site.
Also popular are caravan campsites some that you can actual tow your small caravan to but others are permanent caravans all fully plumbed and have electricity TV etc. A friend of mine from work is going to one of those later this year with his wife and son and daughter in law and their 2 children for a week. As far as I know there will be an area for chilren, probably swimming pool and a social club.
