Most likely if you are reading this review, Galapagos is on your bucket list. Silversea Origin is the way to do it. You will see what you are looking for: Sea Turtles, Sea Lions, Giant Tortoises, Marine Iguanas, Land Iguanas, Blue Footed Boobies (they really have blue feet), Penguins, Sharks, Seals, and all kinds of birds.
We simply cannot imagine that any other operator delivers better tours in as much comfort.
Silversea has a purpose-built ship for exploring the Galapagos. It is well designed for its purpose. Boarding the Zodiacs is well planned. I do not want to promise that it is easy, but it is nowhere close to as difficult as I had feared. And just in case you are wondering why I start with a comment on Zodiacs, Zodiacs are central to all Galapagos tours.
