Isabela Island was my favorite island in the Galapagos. Less touristy than Santa Cruz, much more chilled, and I dare to say, more beautiful.
We went from sunbathing to trekking in the same afternoon, and I had my first snorkeling experience there. If we ever go back to the Galapagos Islands, Isabela will be my first choice. Those looking to travel to the islands should definitely consider going on galapagos tours and cruises.
