This past year 342,209 people visited Channel Islands National Park. Additional day visitors and overnight campers to Santa Rosa and Santa Cruz Islands increased island visitation by about 10 percent. There was a 20 percent increase in visitation to the mainland visitor center in the Ventura Harbor, due in part to the many fourth grade students that participated in the Every Kid in a Park program. The park had a corresponding 75 percent increase in the Junior Ranger program, with over 4,000 kids participating.
