Most people will go to the Galapagos Islands for the fauna. The wildlife on the islands are unlike the rest of the world and are enough to make the visit worth it. The first major animal is the Galapagos tortoise which can only be found on these islands, but sadly there are only 200 have them still alive. These are the tortoises that Darwin studied when he was on the islands. Another unique animal only found here is the Galapagos land iguanas. There is also the only marine iguana that eats out of the ocean. One of the most popular animals with the tourists are the Blue-footed Booby. These are seagull type birds with large blue feet that they show off during mating season. Another popular species is the Galapagos Penguin which is the only tropical penguin still in existance.
Besides the animals that are unlike the rest of the world, there is also weather that will attract many tourists. The islands are scattered about the Equator, however they are located in a current that tends to bring light rains and cooler water during the colder months (June to November). Then during the summer months (December to May) the temperatures increase and the water temperature rises. The amount of rains varies A LOT between the different altitudes and the different islands. On the beaches, the usual hangout spot, there tends to not be much rain.
The views at the islands are some that could be gawked over for a long time. Within the islands, there are 13 main islands and six smaller islands. Each island is slightly different and are used for different reasons. There are just four islands that people live on. The biggest of these is Isabela Island. This is where you will be able to find the airport and other ammenities of civilization. Many of the smaller islands are used for SCUBA diving. One highlights for most people is going snorkeling with penguins at these islands. There are tons of fish and coral around these islands making for some great diving. The sea lions on the islands are also unlike those of other places. They tend to be very curious and are not afraid of people. It is not uncommon to have a sea lion come up to you to see what you are doing.
The Galapagos Islands are not the typical vacation for most, but they can offer much to it's visitors. Because of all the different species, the islands are commonly used for educational purposes. The beaches or the SCUBA diving seem to be the main attractions to the rest of the visitors.
