We (family of 5) took the ferry to Santa Cruz Island & did the sea cave adventure kayak tour. It was such a great experience! Our guide, Zach, was so knowledgeable & worked hard all day to make sure each person was safe, comfortable & happy. We learned so much about the islands, from geology to geography to the native animals. I did not want to get on the ferry to leave at the end of the day. Highly recommend this trip!
