Hey, you can go, too! It's a wonderful, 9-day trip that goes every year out of San Diego. They stop at two offshore islands on the way to San Ignacio, anchor in the lagoon proper for 2 1/2 days, and then you stop at two different islands going back up the coast to San Diego. The last time I went, we had 102 bird species, I've forgotten how many species of cetacean and pinniped, and the best meals I've had outside of cruise lines (chefs on board, not cooks).
The cool thing about the trip is not just the gray whales that come up to your little pangas to be "petted" once you're inside the lagoon, but the side trips off into mangroves and salt flats and beaches, the hikes on the islands, all of which have different geographic, flora and fauna attributes, and the First Class accommodations really make it a once-in-a-lifetime experience. They always have experts on board for birds, astronomy, geology, botany and marine mammals. It's just a whole lot of fun all the way around!
Oh, I'm sorry. Was that too much information? :bounce:
