The Galapagos wildlife are completely unafraid of human visitors. And for this reason the number of visitors allowed each year is limited in an effort to protect the fragile environmental and ecological balance. The most practical method of visiting the Galapagos Islands is by cruise ship. The M/V Galapagos Explorer II offers 3, 4 and 7-night cruises to choose from and these cruises can be easily combined with visits to other South American destinations.
