Would you like to stay in the only hotel on a remote, tropical
island? Well, you’d better take your mobile phone with you,
because there’s only one telephone too! Welcome to Wittmer
Lodge Hotel on Floreana Island. It’s a great place to stay
because it has amazing views of the ocean. It’s also located on a
black, sandy beach, which is quite unusual, and if you want to
see green sand, you can visit the beach at Cormorant Point. So
where is this island?
Floreana Island is part of the Galapagos Islands, which lie in the
Pacific Ocean 906 kilometres west of Ecuador. It was first called
Charles Island, after King Charles II of England. It was later
renamed Floreana Island after Juan José Flores, the first
president of Ecuador, and the island is now ruled by Ecuador.
Floreana Island has the most interesting human history of all of
the Galapagos Islands. It was the home to the first Galapagos
resident – a man from Ireland called Patrick Watkins. He lived
there from 1807 to 1809.
Floreana is only 67 square kilometres, and its highest point is
Cerro Pajas at 640 metres, which is the highest point of the
island’s only volcano. There are approximately a hundred people
living on the island. Around seventy people live in Puerto
Velasco Ibarra, which is the port town; everyone else lives in the
higher parts of the island.
Two of these islanders are the daughter and granddaughter of
Margret Wittmer. Wittmer was the second person ever to settle
on the island. She arrived in 1932 when she was pregnant, with

her husband Heinz and her stepson Harry. When her son Rolf
was born, he was the first person to be born in Galapagos.
Margret lived to the age of 95 and welcomed hundreds of
tourists to her hotel, including presidents. Today her daughter
runs the hotel.
What is daily life like on Floreana? It’s quiet! There is not much
transport to Floreana. There is only a boat that comes from Santa
Cruz island approximately every two weeks. There is just one
school with two teachers, and there aren’t any restaurants or
bars. But if you are interested in the animals, birds and sea life
then Floreana is the perfect destination for you!
