If you like Nature and more specifically, the sea, there is a place that I would like to recommend you to visit, it is called Cofete, in the south west coast of Fuerteventura. What make Cofete so special is the abrupt of its atmosphere that overwhelm you when you just arrive there. You suddenly feel that we are not the center of the Earth, that the power of Nature is greater and a feeling of peace and quiet invades your soul. It is like this place has the power of healing everything....
To go there, you´d better take the bus from the Morro Jable Bus Station, on the top of the town. There are only two departures a day, at ten o'clock in the morning and at two o'clock in the aftenoon, and the last return trip is at a quarter to five. A return ticket will cost you about seventeen euros, not cheap, but the road condition is not suitable for all vehicles. You can also rent a quad, or a 4x4, in Morro Jable Rent a car and spend a day there.
Remenber to take some food and drinks with you, there is only a restaurant in the small village above. And forget a cup and the sun cream.
