Given a rating of Challenge Level 3 (out of a maximum of 10), we consider CSVI to be a beginner service trip that any moderately fit, motivated student can successfully complete. While CSVI is not extremely demanding physically, many of our projects involve physical labor such as trail maintenance, invasive plant removal, or tree planting. Afternoon activities may include moderate hikes, a surf lesson, and snorkeling. Please note that all of Apogee's Challenge Levels are not scientific and are subjectively calculated by the Apogee staff.
