Be careful when suntanning. Due to the nice breeze on the coast the person doesn´t feel the sun burning the skin. Even you are hidden from the sum, be sure to protect your body with a powerful sum block lotion. Clothig, shoes - Don´t forget confortable open sndals (leather or rubber), sun screen, t-shirts (avoid dark colours for they absort the heat).
Avoid walking alone at later of night in desert places which can be dangerous. Use can to use taxis wich security, but the driver usualuly don´t speak english. I recommend you bring a pocket dictionary English-Portuguese-English, you can to buy in the local airport.

Now I can!
