Reading the reviews, seems like you can't find a bad guide in the bunch. Our guide Clay took us out among the caves, passing by one or two that we hit on the way back as the tide had made room for the exit while we were out. Clay was personable, professional, always had a nice thing to say about every person on the trip. Got a bit of history and gelogy along the way. While we checked off visit Channel Islands from the bucket list, we added take the longer kayak tour. We are looking forward to our return visit, whenever that may be!
