Do people in a high school volleyball team usually go to volleyball summer camps?
Usually you practice via summer leagues held with the high schools/colleges in your area. Here you can adjust your play lines up from 6-1 to 5-2 setups, tune up your ability to work as a team, different sets from different places on the court, and practice libero exchanges. Otherwise without a team or a facility, you should practice underpass control, overpass hand positioning, and basic serving mechanics. In addition, yes, some teams do travel to colleges for week long camps. These camps give you valuable teaching tools for you and your players as they will be coached at the college level and criticized to the T.
