Then went back to the island for a walk. There were lots a sea-lions on the island, including a massive bull. Saw lots of great frigatebirds on their nests, some with half-grown chicks. Also saw a yellow warbler which was very conspicuous on the black lava rocks of the shoreline. Returned to the boat. After dinner we set sail for Santa Cruz. Slept badly.
Mon 30th: Took the dinghy to Puerto Ayora, then a bus into the 'highlands'. Had a walk through scrubby woodland looking for giant tortoises. Saw four of them, all huge.
