Buggy Drive at the dunes is a great fun for one day. Hire a buggydriver and load up to 3-4 persons into a buggy and have day that you will remember.
While driving with "motion" at sand-dunes you will be natures own made rollercoster and you will come to one of these places where you can jump into one of these aerial cableways from the top of the dune, all the way down to a sweet water lake - SPLASH.
There will be waiting a "boat" on which you climb or you can swim back to the shore.
From here there will be waiting a carriage on rails. WV Beatle driven engine will then tow you back to the top of the dune.
If this is too frightening for you, there is also similar high dunes from which you will have a sledride down to a lake.
Lacking a bridge (or just providing extra thrill for the touristic buggy tours): manual ferry
8 Real tour retour
2,5 h tour "com emocao" (100 R$): 3 beaches (Gracandu, Pitangui, Jacuma), 2 extraordinary pretty lagunas, dunes...
It's not difficult to find buggy tour provider - THEY will find YOU. Just walk/drive into the village (also suitable for a day trip e.g. from Natal).
Tip: Order "com emocao" (with emotion) only if you are prepared to invest some adrenaline!
