The Monterey Bay Aquarium is an amazing place all by itself. When we went, we were wowed and impressed by all of the exhibits and the staff. We loved it so much we decided to do the insider's tour to check out more of the aquarium. As part of the tour we each got headsets so we could clearly hear the tour guide as she talked about each of the exhibits and what was special and bits of information about the creatures. Also very interesting was being able to see the "behind the scenes" of the exhibits. The tour guide was very knowledgeable and professional and I highly recommend doing this extra tour. It was about $15 per person and the tour was about an hour.
