They can go to camps they just cannot spend time on campus before or after.
When a prospective student-athlete being recruited in the sport of football or basketball participates in an athletics contest or event (including a noninstitutional, private camp or clinic) on a member institution's campus outside of a contact period, it is not permissible for an authorized institutional staff member to have contact with the prospect until the calendar day following his or her release from the competition. The subcommittee noted that NCAA Bylaw 13.1.7.2.2 is designed to prohibit contact in conjunction with campus events conducted outside a contact period and, thus, the prospect must depart the locale of the institution before returning the following day. Further, if a prospect is visiting an institution's campus immediately before participating in an athletics contest or event on the institution's campus, the prospect must depart the locale of the institution the calendar day before the contest or event.
