National Geographic Sea Bird began the day in Bahia Almejas, the southern part of Magdalena Bay. The morning brought a rare treat for the desert—rain. But the clouds and drizzle didn’t last long and our boats headed out for a round of whale watching. Adult gray whales surrounded us at the mouth of the bay. On the way back to the ship, we stopped to watch frigatebirds dance around in the sky. In the afternoon, the ship headed north and we enjoyed a sunset hike through the beautiful sand dunes to Sand Dollar Beach.
