Last night saw a restless sleep. The gentle rocking punctuated by a bump and the constant thrum of the engine was much the same as sleeping on a plane. We awoke to an orange sunrise against an island of red rock. Rabiba is red because of the iron content of the rock. It is the result of a volcanic explosion where the lava was exposed to oxygen in the seawater and the air, oxidising the iron.We went for a short walk along the cliff and looped back inland to the beach. The main plant was the cactus and the wildlife included lizards, sea lions, penguins, pelicans, frigate birds and finches. For what looks like a barren island there is a surprising amount of wildlife.

On leaving the island we saw dolphins and some large fish jumping out of the water. A pair of frigate birds accompanied the boat. The female was sitting on top of the boat and the male was hovering above and occasionally circling.

After lunch we anchored off the west coast of Isla Santiago, at a place called Puerto Egas. There were ruins of a house and some of the buildings which used to be used by salt miners. We did another inland-beach loop with enough marine iguanas to sink a ship. They are almost the same colour as the volcanic rock on which they bask and I almost trod on one on several occasions. There were also crabs, oyster catchers and sea lions.

Another two ships pulled into the same beach and one of the ships held about 80 passengers. It was a task keeping away from the big group, but we managed and finished the day with what will probably be a hundred pictures of iguanas. There must be at least one good one among them.
