After lunch we took the dinghy accords to Santa Cruz Island (one of the biggest with the main town). On Baches Beach we saw piles of brightly coloured crabs, a brown pelican and a blue footed boobie on the rocks. Around in the next bay in shallow water a marine iguana was feasting on the algae on the rocks. Massive black frigate birds were flying over head and a little bird, yellow warbler was jumping around at our feet. In the distance we could see a sea lion playing in the surf. Around further in a lagoon we sat quietly as 5 flamingos in the far corner slowly made their way over to us, brighter than those we had seen in the zoo. While we were waiting two marine iguanas swam energetically across the lagoon - the tour guide said they use their tails like a crocodile. Along this beach is a common place for turtles to nest - the frigate birds were continually flying in low trying to spot baby turtles hatching in the late afternoon. Back on the main beach we headed into the refreshing water for snorkelling. We saw so many brightly coloured fish all around the rocks including massive parrot fish, Sophie swam amongst a massive school of sturgeon fish (grey with bright yellow tail) and saw a sting ray. An Australian guy on our boat had a pelican scoop a large fish out of the sea right next to him! Sophie braved the cold water the longest - both of us intending to hire wetsuits moving forward. So excited and surprised to see so many animals and fish when we were expecting a 'swimming beach'. Already we never want to leave Galápagos!
