Fit for Life

the islands are certainly a paradise (天堂) for wildlife, as there are no natural killers on the islands and the number of boats and visitors is under government control. though you cannot walk freely as darwin did about 200 years ago, each day is as impressive as it could be.
the most well-known animal of the galapagos is the giant tortoise(巨型海龜), which can be seen moving slowly around the highlands of sanra cruz, the second largest island in the archipelago(群島). some of these creatures are so old that they might have been seen in their youth by darwin himself.
despite strict control over activities and timing, your stay on the galapagos will be remembered as a chain of incomparable pictures: diving with sea lions that swim and play within inches of you; feeling small sharks touch your feet as you swim; and, most magically, seeing a whale and her baby surface with a great breath of air.
travelling between the islands and observing the wildlife that so inspired darwin, you will feel as though you are getting a special view of an untouched world. at night you will sleep on board the ship, leaving the wildlife in complete occupation of the islands, which are as undisturbed now as they have been since the beginning of time.
