Daphne Major Island is an example of a tuff crater jutting 394 ft /120 m out of the sea. This island is home to a variety of Galapagos birdlife including Blue Footed Boobies, Frigate and Tropic Birds, to name a few.
Land access on Daphne Major is prohibited so a stop at either Playa Borrero on Santa Cruz or Roca Hundida is included so you can get some snorkeling in this area.
