We did a day trip with Naif.  It was an extraordinary experience and the best way to explore Saudi Arabia.  From the details of arrangement and communication, I could honestly say Naif is the most professional private tour guide I have ever met.  What makes this trip special is the Arabic hospitality that Naif has demonstrated, treating us as guest with kindness and genuineness.  His passion for his country and culture is reflected with his eager to share knowledge of the history and stories about every places we visit.  Naif would go above and beyond to create an unforgettable adventure for his guests.  I highly recommend Naif for an authentic and eye-opening experience of Saudi Arabia.
